Ceramic microbeads are increasingly being used for wear applications, especially for milling ultrafine powder. Research on friction and wear behavior of ceramics has become a more and more important subject in the area. In this paper, three kinds of ceramic microbeads ––mullite-zirconia, zirconium silicate and 95 alumina microbeads which were produced by Colloidal injection moulding technique were tested by SRV high temperature friction and wear test system, which the working condition of the ceramic microbeads as grinding media can be simulated to a certainty. The tests were done under dry friction and water lubrication respectively. Then their worn surfaces were observed using scanning electron microscopy. Through these experiments, the tribological properties and wear mechanisms of the self-wearing ceramic microbeads were investigated.

The tribological performance of Polyetherimide (PEI) composites filled with different Polytetrafluoroethylene (PTFE) content was comparatively evaluated on MM-200 test rig in block-on-ring configuration under dry friction condition. The microstructures of worn surfaces, fractured surfaces and wear mechanisms of the PEI composite were examined under scanning electron microscope (SEM). The variations of elastic modulus and surface hardness with variation in composition were also investigated. The results showed that under conditions of dry friction the PTFE can lower the friction coefficient and reduce wear of the PEI composites. When filled with 10 wt. % PTFE, the composite had the lowest wear rate. For PEI filled with 5wt. % PTFE the friction coefficient was about 0.3 and remained comparatively stable with increase of the PTFE content.

The aim of this study was to investigate the friction and wear behavior of GCr15/1045 steel under different nano-particle additive conditions using a reciprocating horizontal tribometer. The results indicate that the nano-particle additives could decrease friction coefficient of CGr15/1045 steel and reduce the wear of material compared with the dry condition. Nano-particles play an important role of polishing the micro-gibbosity of contact surfaces during the friction process. The nano-particles of Ca10(PO4)6, TiO2 and TiN can form the self-repairing film on the worn surface of 1045 steel. The analysis indicates that the self-repairing effect of nano-particle of TiN is best and the self-repairing effect of nano-particle of TiO2 is worst.

Tribology Performance

9Cr2Mo steel is widely used as measuring and cutting tool steel. The friction and wear behavior of 9Cr2Mo steel was investigated under dry friction and solid lubricant by wear tester. The experiment results show that the friction coefficient of 9Cr2Mo steel is 0.34~0.58 under dry friction and 0.035~0.06 under solid lubricant. With the increase of load , the friction coefficient decreases and the wearing capacity increases under two kinds of conditions. The wearing capacity of 9Cr2Mo steel under solid lubricant is great lower than it under dry friction. The friction process is smooth under solid lubricant. It indicated that the solid lubricant took effect in antifriction and antiwear of 9Cr2Mo steel.

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).

Application of powder boronizing to mechanical industry has been restricted because of the brittleness of boronized layer, which inevitably leads to decrease of service life of boronized parts. Therefore, attention should be paid to reducing the brittleness of boronized layer without decreasing its high hardness. In the present paper, a study on the effect of micro-addition rare earth and chrome on friction and wear behavior of boronized layer was carried out using an MM-200 wear test machine. Compared with that of pure single Fe2B phase, the brittleness of the boronized layer containing minim rare earth and chrome elements, obtained by powder RE-chrome-boronizing, is reduced, which results in increasing the bearing capacity and wear resistance of the boronized layer. The friction and wear mechanism is also briefly analyzed.

Ti(C,N)-based cermets were coated with a TiN/TiAlN coating using ion plating technology. The sliding wear test was performed for the coated cermets and the microstructure, composition and surface roughness of the coated cermets under different velocities and loads were characterized. The results showed that the friction coefficients of the coated cermets were lower than that of the neat cermets. Under the same load, the adhesion phenomenon of the counterpart materials on the specimens was improved and the mean friction coefficient increased with increasing sliding speed. Under the same sliding velocity, the average friction coefficient of the coated cermets was lower under higher load. The wear mechanisms were mainly adhesive wear and abrasive wear.
