Tribological behavior of MoS2–Sb2O3-annealed nanodiamond coating on PEO-LST treated Ti6Al4V
MoS2–Sb2O3 coating is commonly used as solid lubricant for titanium alloys, but the wear-resistance performance is still limited. Core-shell annealed nanodiamond (AND) particle is used as reinforcement for MoS2–Sb2O3 coating on Ti6Al4V substrate treated by plasma electrolytic oxidation (PEO) and laser surface texturing (LST). The incorporation of AND particles into the MoS2–Sb2O3 coating results in a 39 % decrease in friction and significantly reduces wear on the composite coating. Structural transformation of AND particles to amorphous carbon and graphitic structure promotes the densification of top-layer coating, enhancing lubrication and wear-resistance. Change of contact stress by PEO-LST promotes the formation of dense tribofilm and re-orientation of MoS2. This study has implications for the development of solid lubrication coatings for aerospace applications through functional nanomaterials and targeted designed surfaces.
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
