MoS2 reinforced PEEK composite for improved aqueous boundary lubrication

Abstract Polyether-etherketone (PEEK) is a corrosion-resistant material that has been widely used in aqueous lubrication. However, its anti-wear performance must be improved for application the industry. In this study, to improve of PEEK boundary lubrication, PEEK/MoS 2 composites were prepared by ball-milling and spark plasma sintering processes. A competitive MoS mechanism between low shear strength property role promoting wear debris generation influences composites. Experiments demonstrated coefficients friction (COF) rate composite with 0.25 wt% significantly reduced 68% 94%, respectively. Furthermore, was first time could achieve COF less than 0.05 Its verified better PEEK/carbon fiber (CF) Thordon The may potential underwater equipment because outstanding
