Abstract In aero gas turbine engine, copper nickel indium (CuNiIn) and molybdenum loaded disulphide (MoS2) duplex coating is applied on Ti6Al4V blades in bladed disk configuration of low pressure and high pressure compressor. Coating between blade and disk is provided to prevent fretting wear due to direct metal to metal contact of Ti6Al4V. Generally, grit blasting will be done for preparation of the surface before the application of coating. Laser surface texturing (LST) process can be explored by aero engine industry as a new surface preparation process for compressor blades. To compare two different surface preparation methods, Ti6Al4V surface is prepared by two different processes, conventional grit blasting as well as laser surface texturing (LST). LST with different elliptical and square patterns are created on Ti6Al4V. Surface topography is analyzed by SEM and WLI. CuNiIn is sprayed by atmospheric plasma spray (APS) and MoS2 on top of CuNiIn by painting and curing. Effects of surface preparation on coating adherence as well as on tribological properties are studied. The results showed that geometry and dimensions of LST pattern influences the coating adherence and wear performance. LST process can be optimized for better performance and explored as an alternative surface preparation process in industry for thermal spray coatings.
