Abstract:

In the context of a waste heat recovery application on a gasoline engine, tribological investigations have been mandatory in the design of a scroll expander. A new design has been proposed to reach higher temperature and investigations are made to ensure that the material of the parts in contact will provide good tribological performances, i.e. a low coefficient of friction and a low wear rate. This research will also prevent high mechanical losses in the machine and, therefore, increase its thermal efficiency. Some experiments have been conducted on six different materials for the tip seal of

Aim of this work is the development of a methodology for reliable tribological investigations when applying a micro tribometer.

Abstract:

Many attempts have been made in recent centuries to investigate friction, adhesion, lubrication, and wear. Most of the experimental approaches and theories were based on macroscopic experiments, such as tensile and indentation tests. For a long time, only the bulk properties of the materials were considered.Late in this century a new term was created combining all of the above-mentioned properties which deal with the science of interacting material interfaces in relative motion: tribology. The state of the art of science today reveals that processing in nature depends strongly on interfaces th

Abstract:

Dental or tooth wear is a physiological process in the life cycle of teeth. Loss of the occlusal surface may cause excessive tooth wear. Several factors may contribute to tooth wear with different intensities and duration in the oral cavity. The oral cavity is generally compared to a tribological system to determine the various types of wear between teeth and restorative materials and assess the amount of dental wear. However, it is challenging to investigate in vitro and in vivo wear owing to the complexity of tooth wear; thus, a clear correlation between in vitro and in vivo data could not b

Abstract:

Commonly used lubricants in sheet metal forming usually base on mineral or synthetic oils, water based emulsions, drawing films or hotmelts (waxes). However, these conventional lubricants often contain harmful substances to human health and the environment. For this reason, a novel tribological system for dry metal forming has been developed. Basic principle of this new tribological system comprises the use of volatile media such as CO2 (liquid) and N2 (gaseous), which are injected into the contact interface under high pressure via injectors integrated into the tool.

Nevertheless, a major disadvantage results in a poor resistance against wear and tear, e.g. erosion, which is attributed to weak hardness properties.

Abstract:

Present study was carried out for knowing how nanotechnology can be employed for improving the performances in tribology. A significant number of investigations have been reported on the effect of nanoparticles as oil additives. The wear and friction tests were carried on four ball oil tester using ZDDP, NiO and MoS2 nanoparticles in 1wt% combination with mineral oil to provides the reduction in friction and wear. Much of the research suggests that even up to 1% concentrations of such particles are instrumental in reducing wear and friction. Nanoparticle additives have proved to be promising f

Abstract:

Several challenges stand in the way of the production of metal matrix composites (MMCs) such as higher processing temperatures, particulate mixing, particulate–matrix interface bonding issues, and the ability to process into desired geometrical shapes. Although there are many studies showing composites with single particulate reinforcements, studies on composites with multiple reinforcing agents (hybrid composites) are found to be limited. Development of a hybrid particulate composite with optimized mechanical and tribological properties is very significant to suit modern engineering applicati

Abstract:

3D printing is one of the most portentous technologies for the time being. Recently, 3D printing has progressed remarkably and is expected to proceed in numerous applications, such as automotive, medical, wind turbine, and aerospace applications. 3D printing technology opens the door to enhancing and optimizing several applications. Although of such advancement, there is still a lack of the tribological research investigations in this area. This work is devoted to studying the tribological properties of 3D printed polymers (ABS, PLA, Co-polyester, and PCL) for utilization in a wide range of ap

Abstract:

The paper presents results of the investigation of the AlCrN and AlCrN + CrCN coatings, deposited by arc evaporation method on the austenitic steel substrate. Topography studies performed with the use of AFM showed that the roughness value was 24 nm for AlCrN and 14 nm for CrCN. Chemical analysis carried out with energy dispersive X-rays spectroscopy confirmed the chemical composition of the coatings. Transmission electron microscopy (TEM) investigations showed a column structure of AlCrN and CrCN layers with a width in the range of 10–200 nm. Tribological properties analyzed using a scratch t

Abstract:

The paper presents the results of examinations of tribological and corrosion properties of the layers produced on a C45 medium-carbon steel surface in the gas nitriding process combined with subsequent treatment – oxidation and impregnation of corrosion inhibitor. Investigations of the microstructure of these layers and their phase composition were carried out. Hardness of the layers was measured by Vickers method. Tribological properties (linear wear) of the layers were performed by means of the three-cylinder-cone method. Resistance to corrosion was determined by electrochemical methods. The

Abstract:

Friction plate with conical configuration is a novel application in automatic transmission. In order to investigate the tribological performances of novel friction pair with different conical configurations, a series of tests are conducted by using a variable-speed friction test rig. The lubrication regime is evaluated by the friction coefficient curves under different loads. Test results of the friction coefficient under different rotating speeds are analyzed. The difference in the frictional behavior is analyzed for different conical friction pairs. The effects of the cone height and cone an
