In this study, the effects of addition of boron nitride nanoplatelets (BNNPs) upon friction and wear behavior of epoxy resin have been investigated by using pin-on-disk test. It has been reported in the literature that certain amounts of BNNP addition can be useful for enhancement of mechanical properties. Therefore, it is very important to obtain the effect of such addition upon friction and wear performance of epoxy resin. BNNPs have been incorporated at 0.3–0.5–0.7–1 wt %. It is shown that BNNP addition results in decrease in friction coefficient and wear. It is also shown that the best results are obtained with 0.5% nanoplatelet addition. It is also observed that heat conduction of epoxy resin is enhanced by the nanoplatelet addition.

Grind Hardening

The grind-hardening technology utilizes the grinding heat to harden the surface of the workpiece. The friction and wear performance of the grind-hardened layer is one of the important parameters. In this paper, the friction and wear performance of the grind-hardened layer was studied by the friction and wear experiment. The wear rate and the friction coefficient of the grind-hardened steel were studied by comparing with conventional hardened steel and non-hardened steel. The surface worn morphology and the collected wear debris of the grind-hardened steel were observed during the experiment. The wear mechanism of the grind-hardened steel was analyzed under different friction conditions.

ABSTRACTPin-on-disk tests were performed for comparative friction and wear behavior on flat and graded profile boron implanted beryllium samples. Peak, intended boron concentrations of 10, 20, 30 and 40 atom percent were investigated. Auger Electron Spectroscopy was used to determine the boron concentration as a function of depth. Preliminary work was performed to study the effects of (1) a low temperature (450°C, 1–1/2 hours) heat treatment of the implanted specimens and (2) a change in the pin material. All of the boron implanted beryllium samples showed significant improvement versus unimplanted beryllium and an anodized beryllium surface. Graded samples showed comparable friction coefficients but inferior wear resistance with respect to the flat profile samples.

Pin On Disk

Variation in friction and wear properties with relative humidity was obtained with an Sn pin sample on a Cu disk at a constant speed (0.4 m/s), load (6.4 N), and sliding distance (5 km), using a pin-on-disk apparatus. The influence of atmosphere on the tribological properties was investigated, including moisture ranging from 4% to 95 percent relative humidity (RH). It was found that the wear loss of the pin sample is very large at low humidity of around 5 percent RH, but it decreases and reaches saturation at about 50 percent RH. Factors characterizing the friction and wear at 50 percent RH were examined along with surface analysis of the disk. The results showed that the extensive transfer of Sn from pin to disk occurs during sliding and that the friction and wear behavior is determined by the friction and wear of an Sn sliding on Sn. An examination was carried out with an Sn pin sample on a stainless steel disk in comparison with an Sn-Cu couple. It was concluded that the friction and wear behavior is determined by the properties of the film transferred to the disk surface.

Main Factor

Al-matrix self-lubricating which added MoS2 as solid lubricant was prepared by casting under variation in content of Si、Fe、Mn、MoS2、Cr3C2. Friction and wear behavior were investigated on MPX-2000 friction and abrasion machine. The microscopic structure and phases were analyzed by metallographic microscopic and XRD. The results show that the main factor influencing friction coefficient is Si, it can reduce the wear rate. Addition of MoS2 can reduce friction coefficient, Fe is used to improve the mechanical properties. Cr3C2 enhances the wear resistance.

Improvement Effect

Although much has been learned and investigated about environmentally friendly lubricants in recent years, several issues remain critical to their use in specific applications. A key point that could be limiting their utilization is that the effect of green lubricants on the tribological and mechanical properties of the elements has not been thoroughly studied since such attributes determine their performance in industrial applications. For this reason, in this research, the effect of green lubrication on the tribological and hardness properties of AISI 4140 steel was studied. The performance of three bio-based lubricants was studied and compared to that of five of the most representative lubricants. First, the lubricants were chemically and physically characterized. Then, the effect of each lubricant on the friction and wear behavior of the system was analyzed by kinetic friction coefficient, wear rate calculations, and microhardness measurements. In general, the bio-based lubricants exhibited the lowest values of friction and wear. Further the mechanical properties of the systems lubricated by these lubricants were not affected or were affected to a lesser degree.
