Effect of Laser Surface Texturing on Coating Adherence and Tribological Properties of CuNiIn and MoS2 Coating

Copper nickel indium (CuNiIn) and Molybdenum disulphide (MoS2) duplex coating is used in aero engine compressor blades of Ti6Al4V to prevent fretting failure. Surface before roughened by grit blasting process for adhesion. In present study, place blasting, laser surface texturing (LST) preparation compared with blasted surface. Four different elliptical square patterns are created LST on Ti6Al4V. Difference topography between analyzed SEM white light interferometery. CuNiIn deposited atmospheric plasma spray. MoS2 lubricating top spray painting curing. Effect difference microstructure as well tribological properties studied. The results showed that geometry dimensions pattern influence the adherence wear performance. can be optimized better performance explored an alternative industry thermal coatings.
