Full textThis work presents a study on the behavior of different materials under the action of micro-abrasive wear. A micro-abrasive wear testing machine with fixed sphere was designed and constructed, presenting a mechanical configuration with differences with respect to those found in the literature (Gee et al., 2005). M2 tool steel and WC-Co P20 were used as testing specimen materials. Ball materials were cemented AISI 1010 steel and quenched and tempered AISI 52100 steel. During the tests, an abrasive slurry, prepared with black silicon carbide (SiC) particles (average particle size of 5 µm), was supplied to the contact between the specimen and the ball. Initially, preliminary tests were conducted to study the wear mode transitions that can occur during the micro-abrasive wear and to analyze the operational conditions of the equipment. The wear mode transitions were evaluated as a function of the applied normal load and of the materials used. The results indicated good reproducibility and qualitative agreement with those found in the litarature. Later, a new set of tests was conducted, which analyzed the evolution of the abrasive wear modes and the achievement of steady state wear as a function of sliding distance. The results indicated a continuous variation in the abrasive wear modes with sliding distance. Additionally, in some tests, the wear coefficient tended to stabilize in constant value, which characterizes the achievement of steady state regime. However, in other tests, the wear coefficient presented a non constant evolution of wear coefficient with the sliding distance, which denotes that the constant regime of wear was not obtained.

Full textThe micro-scale abrasive wear test by rotative ball has gained large acceptance in universities and research centers, being widely used in studies on the abrasive wear of materials. Two wear modes are usually observed in this type of test: rolling abrasion results when the abrasive particles roll on the surface of the tested specimen, while grooving abrasion is observed when the abrasive particles slide; the type of wear mode has a significant effect on the overall behaviour of a tribological system. Several works on the friction coefficient during abrasive wear tests are available in the literature, but only a few were dedicated to the friction coefficient in micro-abrasive wear tests conducted with rotating ball. Additionally, recent works have identified that results may also be affected by the change in contact pressure that occurs when tests are conducted with constant applied force. Thus, the purpose of this work is to study the relationship between friction coefficient and abrasive wear modes in ball-cratering wear tests conducted at constant normal force and constant pressure. Micro-scale abrasive wear tests were conducted with a ball of AISI 52100 steel and a specimen of AISI H10 tool steel. The abrasive slurry was prepared with black silicon carbide (SiC) particles (average particle size of 3 m) and distilled water. Two constant normal force values and two constant pressure values were selected for the tests. The tangential and normal loads were monitored throughout the tests and their ratio was calculated to provide an indication of the friction coefficient. In all cases, optical microscopy analysis of the worn craters revelated only the presence of grooving abrasion. However, a more detailed analysis conducted by SEM has indicated that different degrees of rolling abrasion have also occurred along the grooves. The results have also shown that: i) the sliding distance presents an important role on the wear mode transition, ii) for the selected values of constant normal force and constant pressure, the friction coefficient presented, approximately, the same range of values and ii) the friction coefficient was independent of the wear rate.

Full textThe objective of this work is the development of a monitoring system able to identify in process the grinding wheel wear mechanism. Thus, initially the physical quantities, sensors types and monitoring systems strategies, developing status and their applications were researched. To get a reliable and efficient system was necessary a detailed study of the grinding wheel wear mechanism phenomenology. This study allows to define parameters in order to identify which type of wear is occurring, using indication obtained by the monitoring variables whose behavior is known, such as grinding power, vibration or metrological measurement. Two grinding wheel surface optical mapping systems are presented, those systems were utilized as base to developing a new mapping system of Grinding Acoustic Energy Distribution (DEAR). Experiments have been done with the new system, monitoring simultaneously other physical quantities, looking for a way to link the mapping graphic patterns generates by the new system with the wear type which was occurring, based on information obtained from the wear mechanism study. The results and analysis have shown that the DEAR map can be used to identify the predominant wear mechanism type which is occurring on a grinding wheel, in process. This information is very useful in the corrective actions when facing a grinding problem.

Full textIn this research, the effect of abrasive size on the wear resistance of five metallic materials was investigated. Abrasive wear tests using a pin test on alumina paper were carried out using abrasive sizes between 16 µm and 192 µm. The wear surface of the specimens was examined by scanning electron microscopy for identifying the wear micromechanism and the type of microchips formed on the abrasive paper (wear debris). In a first series of experiments mottled cast iron samples with M 3 C carbides were tested. The samples were quenched and tempered in temperatures ranging from 300°C to 600°C. For small abrasive particles, the wear mass loss increased linearly with the increase of particle size. However, for higher abrasive sizes the wear mass loss increased much more slowly. For lower abrasive sizes the main wear mechanism was microcutting. For higher abrasive sizes, the main wear mechanism was microploughing. In a second series of experiments white cast iron with M 3 C carbide with austenitic and martensitic matrix were tested. The results show that the mass loss for cast irons with austenitic and martensitic matrices increases linearly with the increase of particle size until the critical particle size is reached. The cast iron with austenitic matrix presented a critical abrasive size of 36 µm and for the martensitic cast iron, the critical particle size was about 116 µm. After the critical particle size is reached, the rate of mass loss of the cast iron with austenitic matrix diminishes to a lower linear rate, and for cast irons with martensitic matrix the curve of mass loss is non-linear and flattens when the critical particle size is reached. It becomes, then, constant, independent of additional size increases. The abrasive paper in contact with the iron of both austenitic and martensitic matrices presents fine continuous microchips and the main wear mechanism was microcutting before reaching critical particle size, and after that it presents deformed discontinuous microchips and the main wear mechanism was microploughing. This behavior of change in rates after reaching a critical size happened not only for mass loss versus abrasive size, but it was also observed both in curves of friction coefficient and specific cutting energy versus abrasive size. In a third series of experiments aluminum and AISI 1045 steel were tested. The first (FCC structure) showed similar behavior to that observed in the white cast iron with austenitic matrix and the latter showed similar behavior to that observed in white cast iron with martensitic matrix. Both aluminum and AISI 1045 steel show similar changes in the microchips morphology and in the wear micromechanisms, something that had been observed before in materials with hard second phase. In a fourth series of experiments gray cast iron was tested in order to demonstrate the relationship between the abrasive wear micromechanisms and the type of microchips, before and after achieving critical abrasive size. The grey cast iron did not show a transition in the curve of abrasive size against mass loss. The morphology of the chips was similar for the different sizes of abrasive (discontinuous). However, smaller abrasive sizes some thin continuous microchips were formed. The main abrasive wear micromechanism was microcutting for the different abrasives sizes tested. Therefore, it was shown that the critical abrasive size is related to the wear micromechanisms and the microchips morphology.

Este trabalho tem por objetivo qualificar a resistência ao desgaste abrasivo de metais duros, compostos por carboneto de tungstênio e ligantes à base de níquel, endurecidos por elementos em solução sólida dissolvidos "in situ"(durante a sinterização). Esses ligantes foram desenvolvidos em trabalhos anteriores no LABMAT (Laboratório de Materiais - Eng Mecanica da UFSC). Devido aos empirismos das técnicas de medição de desgaste, as comparações dos resultados do novo metal duro foram feitas com o convencional (WC-Co) submetido ao mesmo ensaio. Com os resultados obtidos, vários gráficos foram traçados mostrando interessantes relações entre a propriedade da resistência ao desgaste abrasivo e outras propriedades e características.

A presente pesquisa teve como objetivo, investigar o efeito do teor de carbono e do tamanho do abrasivo na resistência ao desgaste e no fenômeno de encruamento superficial de quatro aços Hadfield. Para esse estudo, foi montado, o equipamento pino contra disco, e, como abrasivo utilizou-se lixas de ferro, com o tamanho médio entre 36 µm e 93 µm. Para o alcance do objetivo proposto foram delimitados materiais e métodos, a saber: (a) montagem do abrasômetro pino-disco a partir de um dispositivo desativado disponibilizado pelo LFS-USP; (b) confrontar resultados experimentais – dois materiais (Aço 1045 e alumínio 6351) foram submetidos a ensaios realizados na UFPE e USP para fins de estudos comparativos; (c) avaliação da influência de parâmetros do ensaio – três abrasivos com diferentes tamanhos de partículas e diferentes cargas foram submetidos e avaliados mediante o desgaste abrasivo; (d) avaliação do comportamento de diferentes composições do aço Hadfield perante ensaios de abrasividade – aços contendo quatro diferentes teores de carbono foram submetidos a ensaios com lixas #220 e #320; (e) análise das superfícies desgastadas – após os ensaios dos materiais, as superfícies foram realizadas análises por microscópio eletrônico de varredura (MEV) das superfícies desgastadas. Os resultados obtidos com o equipamento na metodologia empregada tiveram uma boa reprodutibilidade. Foram observadas diferenças nos resultados entre os equipamentos da UFPE e da USP. Quanto a este tópico, o desgaste abrasivo do aço Hadfield foi influenciado pelo teor de carbono apresentando uma relação em que maiores teores demonstraram menor efeito de desgaste, diferentes tamanhos de abrasivo ocasionam um efeito de encruamento significativo, onde se observou o ganho de dureza em aços com menores teores de carbono. Contudo, foi apresentada uma oscilação do efeito no abrasivo #320. As micrografias revelaram microssulcos e microcortes provenientes do ensaio e não foram observadas diferenças nas marcas de desgaste quando utilizados tamanhos diferentes de partícula abrasiva. Ao final, chegou-se a conclusão de que os resultados obtidos demonstram que o teor de carbono influência na resistência ao desgaste do aço e consequentemente no encruamento superficial do aço. Observa-se também a influência do tamanho do abrasivo e carga aplicada o ensaio.
This research aimed to investigate the effect of the carbon content and the size of the abrasive in the wear resistance and surface hardening phenomenon four Hadfield steel. For this study , has been assembled , the disc against pin device and abrasive was used iron sandpapers, with average size between 36 m and 93 micrometers. To achieve the proposed objectives were defined materials and methods, namely: (a) mounting the pindisk abrasômetro from a disabled device provided by the LFS-USP; (b) comparing experimental results - two materials (1045 steel and aluminum 6351) were submitted to tests performed at university and USP for purposes of comparative studies; (c) evaluation of the influence of the test parameters - Three abrasive particles with different sizes and different loads were submitted and evaluated by the abrasive wear; (d) assessment of the behavior of different steel compositions Hadfield before abrasiveness tests - steels containing four different carbon contents were subjected to tests with sandpaper # 220 and # 320; (e) analysis of the worn surfaces - after the tests of materials different analyzes were performed by scanning electron microscope (SEM) of worn surfaces. The results obtained with the equipment in the methodology employed had good reproducibility. There were differences in results between the equipment and the UFPE USP. On this topic, the abrasive wear Hadfield steel was influenced by carbon having a relationship in which higher levels showed less wear effect, different abrasive sizes cause a significant strain hardening effect, which was observed gain hardness steel with lower carbon content. However, an oscillation of the abrasive effect on the # 320 was presented. The micrographs revealed microssulcos and microcuts from test and differences were observed in wear marks when using different sizes of abrasive particle. In the end, came to the conclusion that the results show that the influence of carbon content in the wear resistance of steel and consequently the surface of the steel hardening. It is also observed the influence of abrasive size and load applied to the test.

Full textThis work presents an analysis of the welding conditions and its effects in the abrasive wear of hardfacings. The hardfacings were obtained by submerged arc surfacing. The welding variables were changed and the commercials fluxes were used. Two groups of welding variables were used (group 01: a traveI speed of 55 cm/min, an electrode extension of 35,0 mm, a voltage of 30V and an amperage of 450A; group 02: a traveI speed of 50 cm/min, an electrode extension of 25,0 mm, a voltage of 26V and an amperage of 440A) and four commercials fluxes (E, M, L e R designated) establishing eight welding conditions. Double-Iayered ot three beads were deposited (applied) on a SAE 1020 base metal plate. Direct current electrode negative polarity (CC-) were used in both groups of welding. The low stress abrasion resistance evaluation was carried out by dry sand/rubber wheel apparatus according to the ASTM G65-94. The microstructural analysis were done by optical microscopy and the worn surface analysis were done by scanning electronic microscopy. The abrasion resistance of the group 01 was superior as compared to the group 02, independent of the fluxe was used. The fluxes E and R presented the best results and the befter abrasion resistant microstructure was lath martensite.

Sand cores are widely used at automotive foundries. The impact of sand on the surface of the tooling caused by the injection pressure causes wear on internal geometry, that interferes in the assembly of sand cores and dimensional of casting, and the maintenance of tooling is a bigger concern of the automotive foundries. When a core box show wear, some procedures may be applied for re-use of tooling, but, however, a better understanding of the wear process that occurs on the surface of the inserts will improve the life time of the core box. The purpose of this study is to better understand the wear mechanism that suffers tooling and form a knowledge base of wear on foundry tooling. In this study was present a comparative study on wear resistance among 05 different types of steels used in the manufacture of foundry tooling. The wear resistance has studied by tests on steel specimens used in the manufacture of foundry tooling in the rubber wheel abrasometer, as the pattern set by the technical ASTM G65-04.
Núcleos de areia são largamente utilizados em fundições de peças automotivas. O impacto da areia sobre a superfície do ferramental causado pela injeção sob pressão provoca desgaste na sua geometria interna, o que interfere na montagem dos núcleos de areia e dimensional da peça fundida, sendo que, a manutenção dos ferramentais é uma das grandes preocupações da fundição de peças automotivas. Quando uma caixa de macho apresenta desgaste, certos procedimentos podem ser aplicados para reutilização do ferramental, mas, no entanto, o melhor conhecimento do processo de desgaste que ocorre na superfície dos insertos irá melhorar a vida útil da caixa de macho. O objetivo do trabalho é entender melhor o mecanismo de desgaste que o ferramental sofre e formar uma base de conhecimento sobre desgaste em ferramentais de fundição. Neste trabalho foi realizado um estudo comparativo na resistência ao desgaste entre 05 diferentes tipos de aços utilizados na confecção de ferramentais de macharia Cold Box. A resistência ao desgaste foi estudada através de testes em corpos de prova de aços utilizados na fabricação de ferramentais em abrasômetro do tipo roda de borracha, conforme o padrão estabelecido pela norma técnica ASTM G-65-04.

Full textThe wear in machines and equipments is one of the main sources of economic losses. Nowadays many studies have been conducted to develop new materials and coverages to produce wear resistance. The hardfacing is one of most common methods to produce a deposit having properties not intrinsic to that of the base material. The main objective of this work is to study the viability of using different alloys compositions to produce covered electrodes for shielded metal arc welding (SMAW) resistant to abrasive wear. The covered electrodes were produced adding chromiumcarbon and tungsten-carbon to rutile-calcium carbide-fluorite base. Comparison and evaluation of wear resistance of the developed electrodes was based in ASTM G65-91 wear tests, deposit chemical compositions and the resultant microstructures. The results shown that electrodes containing additions of C-W 7 % and C-Cr 1.5 % produced best performance of wear test deposits. These compositions produced deposits containing the higher amounts of carbides and exhibit higher hardness values.

O objetivo desse estudo, in vitro, foi avaliar a resistência ao desgaste abrasivo das resinas compostas universais Charisma/CH (Heraeus Kulzer), Esthet-X/EX (Dentsply Caulk), Fill Magic/FM (Vigodent), Filtek Supreme/SU (3M ESPE), Filtek Z100/ Z1 (3M ESPE), Filtek Z250/Z2 (3M ESPE), Herculite XRV/HE (Kerr Dental), Opallis/OP (FGM), Te-econom/TN (Ivoclar Vivadent) e Tetric Ceram/TC (Ivoclar Vivadent). Foram confeccionados 8 corpos-de-prova, na cor A2, com formatos cilíndricos (8,0 mm de diâmetro X 2,0 mm de espessura) de cada material. A resistência ao desgaste abrasivo foi avaliada através de análises das alterações na massa e na rugosidade superficial das amostras submetidas à escovação simulada. As mensurações iniciais (pré-escovação simulada) e finais (pós-escovação simulada) de massa foram obtidas através de balança eletrônica com precisão de 0,0001g. As aferições iniciais e finais da rugosidade superficial foram feitas com uma sonda mecânica de 5µm acoplada ao rugosímetro Perthometer S8P (Mahr), com velocidade constante de 0,15mm/s e força de 0,8mN, utilizando o parâmetro de medição Ra expresso em µm, com cut-off de 0,25mm e comprimento de avaliação de 1,25mm. O teste abrasivo foi realizado em uma máquina de escovação simulada, utilizando escovas dentais de cerdas macias e pontas arredondadas, sob 200g de carga, com velocidade de 374 ciclos/min e solução de dentifrício e água deionizada na proporção de 1:2. As amostras foram submetidas a 50.000 ciclos de escovação. As escovas foram substituídas a cada 25.000 ciclos e a solução foi constantemente reposta durante o teste. Para a avaliação das alterações decorrentes do teste abrasivo foram calculadas as diferenças entre as médias finais e iniciais de massa e de rugosidade superficial e os valores obtidos foram convertidos em porcentagem. Os dados foram analisados estatisticamente através dos testes t pareado, ANOVA, Scheffé e correlação de Pearson (p<0,05). Os resultados demonstraram que todos os materiais apresentaram redução estatisticamente significante da massa e aumento estatisticamente significante da rugosidade superficial após a escovação simulada (p < 0,0001). Considerando as alterações na massa, a ordem crescente de resistência à abrasão dos materiais avaliados foi (OP=Z2) > Z1 > TC > (HE=CH) > FM > TN > SU > EX. Com relação às alterações na rugosidade superficial, a ordem crescente de resistência à abrasão dos materiais avaliados foi EX > (HE = SU = TC = CH = FM) > (TC = CH = FM = OP) > (OP = Z2 = TN = Z1). Os métodos de avaliação de resistência ao desgaste não possuem correlação. Com base nos resultados concluiu-se que dentre as resinas compostas universais avaliadas existem diferenças na resistência à abrasão, entretanto, todas desgastam e ficam mais rugosas em conseqüência de forças abrasivas por escovação simulada. As alterações de massa e de rugosidade superficial das resinas compostas não estão correlacionadas.
