Intersplat Friction Force and Splat Sliding in a Plasma-Sprayed Aluminum Allo…

ABSTRACT This study computes the friction force during splat sliding in the plasma-sprayed Al-Si coating based on the instrumented depth-sensing nanoindentation and microindentation experiments. A small intersplat friction force (∼10-4 N) contributes to the occurrence of the splat sliding. As compared with nanoindentation, more and more splat sliding occurs during microindentation because o…
