Abstract: This work presents and discusses the antiwear behaviour of nanoparticle suspensions in a polyalphaolefin (PAO 6). CuO, ZnO and ZrO 2 nanoparticles were separately dispersed at 0.5%, 1.0% and 2.0%wt. in PAO 6 using an ultrasonic probe for 2 min. AW properties were obtained using a TE53SLIM tribometer with a block-on-ring configuration. Tests were made under a load of 165 N, sliding speed of 2 m/s and a total distance of 3.066 m. Wear surfaces were analysed by scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS) after wear tests. The study led to the following conclusions: all nanoparticle suspensions exhibited reductions in friction and wear compared to the base oil; the suspensions with 0.5% of ZnO and ZrO 2 had the best general tribological behaviour, exhibiting high friction and wear reduction values even at low deposition levels on the wear surface; CuO suspensions showed the highest friction coefficient and lowest wear per nanoparticle content of 2%; and the antiwear mechanism of nanoparticulate additive was produced by tribo-sintering.

Abstract: A solid lubricant composite material was made by compression molding PTFE and 40 nm alumina particles. Prior to compression molding the constituent powders were blended using a jet milling apparatus. Composites from 0 to 20 wt.% were prepared. These composites were tested against a polished stainless steel counterface on a reciprocating tribometer. The experimental conditions were a contact pressure of 6.4 MPa, a stroke length of 50 mm, and a sliding speed of 50 mm/s. The friction coefficient of the composite increased over unfilled samples from roughly μ =0.15 to μ =0.2. At filler concentrations of 20 wt.%, the wear resistance improved 600×. The wear resistance of this composite increased monotonically with increasing filler concentration and no optimum filler fraction was found.

Abstract: The wear behaviour of thermal oxidation (TO)-treated as well as untreated Ti6Al4V alloy has been investigated using an Amsler tribometer in rolling–sliding motion under boundary lubrication conditions. The results show that the TO treatment can significantly enhance the wear resistance of Ti6Al4V alloy. Based on the experimental results, in conjunction with systematic analyses, the wear-reduction mechanisms involved in the TO-treated material are discussed. It was found that the significantly reduced tendency to adhesive wear and the improved wettability, which increases the effectiveness of lubrication, have contributed to the enhanced wear resistance of the TO-treated material.
