Abstract:The molybdenum sulfide/lanthanum fluoride/ polyimide (MoS 2 /LaF 3 /PI) coating was synthesized and irradiated by ultraviolet (UV) or atomic oxygen (AO). The friction and wear behavior were evaluated sliding against GCr15 steel balls (ASTM A295:1998) using a ball-on-disk tribology test rig. This paper aims to discuss these issues. The chemical structure of the irradiated surface was examined by Fourier transform infrared (FTIR) spectroscopy. The worn morphologies of the coatings and counterpart were observed b… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
