Abstract:
Aluminium-silicon alloy pins were dry slid in unidirectional and reciprocating sliding against steel counterfaces in a normal pressure range of 0.39–26 M Pa and a sliding speed range of 0.6–1.8 m/s. Changing the mode of sliding from unidirectional to reciprocating as well as an increase in reciprocating speed were found to affect wear and seizure resistances adversely. Alloying additions of copper and magnesium to the base metal, on the other hand, were found to improve both of these properties. The temperature rise of the pin during sliding and the mechanical behaviour of the test alloys in compression in a temperature range of 25 300 °C and a strain rate range of 0.1–100/s were recorded and the data incorporated into a qualitative model to account for the wear and seizure behaviour of the test materials.

Abstract:
Friction coefficient and linear wear rate of polyester-carbon nanotubes composites were investigated through ball-on-flat reciprocating test, under dry sliding contact. Three types of nanoscopic fillers were used: multiwall carbon nanotubes (MWCNT), functionalized multiwall carbon nanotubes (MWCNT-COOH) and singlewall carbon nanotubes (SWCNT), with three values of weight content 0.1, 0.15 and 0.2 wt%. Comparative analysis was done for polyester and its composites tested over 14 m sliding distance, under three values of load, 30 N, 40 N and 50 N. Composites containing MWCNT underwent a decrease in friction coefficient and linear wear rate only in case of 50N loading. An improvement of wear behavior under 50N loading was obtained for the composite with 0.10 wt% functionalized carbon nanotubes. Generally, better values of wear rate at 50 N loading were recorded in case of composites with 0.15 wt% and 0.20 wt% MWCNT and SWCNT, respectively. Optical and electronic investigation of the worn surfaces revealed the occurrence of abrasive, adhesive and fatigue wear. Abrasive wear is due to the hard particles detached from the counterpart which produce scratches and furrows on sliding track. Adhesive wear results when soft particle of polymer are caught and blocked among the asperities of counterpart, and it develops over a local area, being influenced by temperature rise. Fatigue and abrasive wear are responsible for the formation of the 3rd body between contacting parts which affects the friction and wear behavior. Morphological analysis of worn surface showed the rise of transfer film that induces instability of wear parameters.

Abstract:
This paper presents an experimental evaluation of friction and wear properties of WC-Cocemented carbides. A comparison is made between unlubricated rotating and linearly reciprocating pin-onplate sliding pairs. The plate specimens were WC-10wt%Co grades surface finished by polishing orsequential wire-EDM steps, whereas WC-6wt%Co pins were used as counter body. The tests were carriedout at room temperature using a sliding speed of 0.30m/s and mean Hertzain contact pressures of 1.76 and2.08 GPa, i.e., normal contact loads of 15N and 25N, respectively. The worn surfaces on plate sampleswere quantified in terms of 2–D wear profiles obtained by means of surface topography scanningequipment. Wear mechanisms such as polishing and abrasion were identified using optical microscopy.Inferior tribological characteristics for wire-EDM surface finish compared to polishing were found. Higherfriction coefficient and wear levels were measured in unidirectional rotating sliding experiments comparedto linearly reciprocating test conditions.

Abstract:
Wear and corrosion resistant multi-phase transition metal silicides coatings including W2Ni3Si/W5Si3, Ti5Si3/NiTi2, Ti2Ni3Si/NiTi, etc, were developed and fabricated by laser cladding process. Tribological properties were evaluated under dry sliding and reciprocating fretting wear test conditions and the responding wear mechanisms were discussed as functions of microstructure constitutions and test conditions. High temperature oxidation resistance of the coatings was investigated. The coatings exhibited excellent combination of room and high temperature metallic sliding wear resistance, fretting propertiy, metallic tribological compatibility, good oxidation resistance and abnormal wear-load dependence. Applications of the coatings were prospected for the aerospace, petrochemical and energy-processing industries.

Abstract:
This paper presents an experimental evaluation of friction and wear properties of a composite material-moglice - made by Diamant Metallplastic GmbH company, from Germany. This material is a polymeric matrix reinforced with particles of cristobalite (αSiO2) and molybdenum disulphide (MoS2). The material is recommended by the manufacturer for repairing metal parts. This material was tribologically tested in dry friction conditions, on a ball on flat configuration, using the reciprocating method, on a CETR UMT-2 tribometer (Bruker Corporation). The counterpart was a steel ball. The tests were performed at room temperature in normal conditions of relative humidity of 40-60% using an average sliding speed of 3.5 mm/s. The tests were carried out at normal loads of 20, 30, 40 and 50N over a sliding distance of 100 m. The wear traces obtained were optically examined with μSCAN laser profilometer (NANOFOCUS).

Abstract:
Tungsten carbide based hardmetals with cobalt binder phase are widely used in engineering industries for their excellent mechanical properties and outstanding wear performance. Reciprocative sliding wear behaviour of a number of WC-Co based hardmetal grades was investigated using a small-scale pin-on-plate tribometer. Test samples were manufactured by electro-discharge machining (EDM) with various surface finishing regimes. SEM topographies and cross-section views of the cemented carbides were obtained both before and after dry friction tests, revealing distinctive wear mechanisms. The generated wear loss was quantified topographically using surface scanning equipment. Wear debris particles were collected and examined by EDX and TEM analysis. Based on experimental results, the execution of consecutive gradually finer EDM cutting steps was found to considerably enhance wear performance. Furthermore, a significant influence of contact load, sliding movement duration, application of lubricant and wear debris formation on wear rate and friction was established.

Abstract:
Tribological properties of glass fiber-reinforced polymer (GFRP) composites used in reciprocating contact should be improved to secure the efficiency and safety because of risks of abrasion, adhesion, and fatigue deficiency amidst fiber, matrix, or interphase. This paper investigates the influence of graphene reinforcement on the wear resistance of a GFRP composite. Graphene was integrated into a typical GFRP composite as the surface coating using a modified resin film infusion method with the percolating paper assisted. Dry reciprocating sliding tests were performed against a stainless steel ball moving in a direction 45 degrees to the fiber orientation. The morphology of the worn surface was observed, and the corresponding wear mechanisms are discussed. Results suggest that the prepared graphene coating improves the wear resistance of the GFRP composite. The protected GFRP laminates remained intact during the first 20 min of the wear test and only a small fraction of fibers were broken after 60 min test. Furthermore, abrasive debris and fiber breaks originating from composite were markedly reduced, likely owing to the formation of a protective transfer film between the surface of the modified composite and the rubbing counterpart.

Abstract:
In this work, a study was carried out on the friction and wear behavior of flame thermal sprayed NiCrBSiFeC-WC(Co) composite and NiCrBSiFeC coatings subjected to severe wear conditions. For this purpose, flame remelted samples were tested in reciprocating wear conditions based on a cylinder-on-flat configuration. The wear assessment of the coatings was achieved using scanning electron microscopy (SEM) and 3D optical profilometry. The microstructure and the mechanical properties of the coatings were investigated using SEM, EDS and XRD techniques as along with indentation tests. The tribological behavior of the substrate and the coatings was successfully studied thanks to wear tests conducted on an adapted multi test apparatus. The results show that both NiCrBSiFeC and composite coatings induced a significant increase in the steel substrate hardness and wear resistance due to the formation of precipitates with high hardness well dispersed within an ultra-crystalline structure. Besides, adding WC(Co) to NiCrBSiFeC leads to a composite coating with hardness and wear resistance further improved. In return, it increases the coefficient of friction (COF) and the coatings’ roughness. Furthermore, improvements in the surface hardness, the roughness and the coating-substrate adhesion were attained after the remelting process for both NiCrBSiFeC and NiCrBSiFeC-WC(Co) coatings. Wear tracks investigations indicated that reciprocating dry sliding based on cylinder-on-flat test configuration promote several wear mechanisms that may occur simultaneously.

Abstract:
In the present paper, plasma surface alloying was implemented on powder metallurgy gears to improve its wear resistance based on double glow plasma surface metallurgy technology. A W-Mo alloy coating was obtained in the process. The morphology, microstructure and phase composition were investigated by SEM, EDS and XRD. The hardness was examined by Vickers hardness test and nanoindentation test. The tribological behavior of powder metallurgy gears before and after plasma surface alloying was evaluated on a ball-on-disc reciprocating sliding tribometer under dry sliding condition at room temperature. The results indicate that the W-Mo alloy coating is homogeneous without defects, which includes deposition layer and interdiffusion layer. The average microhardness of powder metallurgy gears before and after plasma surface alloying is 145.8 HV0.1 and 344.4 HV0.1, respectively; Nano hardness of deposition layer and interdiffusion layer is 5.76 GPa, 14.35 GPa, respectively. The specific wear rate of W-Mo alloy coating is lower than original PM gears. The wear mechanism of W-Mo alloy coating is slight adhesive wear. The W-Mo alloy coating prepared by double glow plasma surface alloying technology can effectively improve wear resistance of powder metallurgy gears.
