Intersplat Friction Force and Splat Sliding in a Plasma-Sprayed Aluminum Alloy Coating during Nanoindentation and Microindentation
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 of the increase in the applied load, which accounts for the ∼26% loss of the elastic modulus.
