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.

The wear behavior of different plant abrasive to 45# steel was studied by using an abrasive rubber wheel tester. The worn surface of the frictional samples morphology was observed by using Scanning Electron Microscopy, and the wearing mechanism of different abrasive to 45# steel was analyzed. The results show that: on the experiment conditions, the wear loss from big to small is alfalfa abrasive, corn abrasive and wheat abrasive, and the wear rules of corn abrasive and wheat abrasive are similar, but the wear loss of alfalfa abrasive is much higher than the former two. The wear dominant mechanism of the wheat abrasive to 45# steel is mechanical polishing, the wear dominant mechanism of the corn abrasive to 45# steel is mechanical polishing and adhesive wear, the wear dominant mechanism of the alfalfa abrasive to 45#steel is micro-cutting and adhesive wear.

The effect of load on the friction and wear behavior of NBR and FPM was investigated using a ring-on-block tester under dry sliding. The hardness and morphology of worn surface were measured using Shore Hardness and stereo microscope, respectively. The results showed that at the load of 50, 100 and 150N, the wear loss of NBR was lower than that of FPM and the frictional coefficient of NBR was the same as that of FPM. While at the load of 175, 200 and 225N, the wear loss and frictional coefficient of NBR were higher than that of FPM. The reason for the variation of friction and wear behavior of NBR and FPM under different load was discussed preliminarily.

Friction and wear behavior of Polyoxymethylene/Poly (lactic acid) blends (POM/PLA) was investigated to study effect of PLA content on friction and wear properties. The sliding experiments were carried out by Frictoron EFM-III machine. POM blends sliding against the carbon steel (AISI 1045) counterpart under 200 N of pressure load, 100 mm/s of sliding speed for 60 minutes. The wear weigh loss was measured after wear experiment. Wear profile and worn surface were observed by SEM. It was found that friction coefficient of neat POM is lower than neat PLA. However, the incorporation of PLA into POM led to an increment of friction coefficient of POM blends both of 40% and 60% PLA content that over than neat POM and PLA. While wear weigh loss resulted the increasing with increasing of PLA content, which were supported by wear prolife photographs. The deformation of neat PLA and blends on worn surface originated from adhesive due to the thermal softening and melting behavior, while neat POM reveals the plough action behavior.

Cutting Tool Materials

The friction and wear behavior of cutting tool materials keeps an issue. In this study, an high temperature tribometre (UMT-2) was used to investigated the tribology properties and mechanism of two kinds of typical cutting tool materials. Commonly used cemented carbide (ZU5) and ceramic (AT) were chosen. The characteristics as to wear rate, friction coefficient and worn surface were studied. From the results, we found that the ceramic had better wear resistance than the cemented carbide. The friction coefficient of cemented carbide decreased with the increase of ambient temperature while the ceramic exhibited an inverse tendency. Finally, the probable wear mechanism was discussed.

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.

In the present work, SiC was pressureless solid state sintered with 3 wt% C and 0.6 wt% B4C as sintering additives. The friction and wear behavior of the PSSS SiC ceramics was investigated by using a block-on-ring tribometer. The wear volume and friction coefficient was measured. It is as expected that the friction coefficient increased with the elevation of the normal load and sliding speed. The microstructure of the worn surface was observed, based on which the wear mechanism was analyzed. Different degrees of oxidation during the friction process was found and the degree of oxidation was related to the severity of wear. The normal load was found to exert great influence on the wear of the SSiC ceramics.

The characteristics of the 1045 steel pairs using serpentine particles as grease lubricant additive were investigated by an AMSLER friction and wear tester. The surface topographies and composition of the worn surface of 1045 steel rings were identified by SEM and XPS. The results show that the additives can form a self-repairing film on the worn metal surface. It can reduce the abrasion of the friction pairs significantly. The main elemental compositions of the film are Fe, O, Si, C and Mg, which indicates that the additives directly take part in the formation of the self-repairing film.
