Abstract
Three different scratch modes were used to induce deformation in TiN coating deposited on D9 substrate. The consequent surface damage was analyzed using optical and scanning electron microscopy. Main deformation mechanisms found during Progressive Load Scratch Test and Constant Load Scratch Test were cohesive cracking, coating spallation and adhesive failure. However, ductile fracture was induced during Multi Pass Scratch Tests (MPSTs) performed at three different loads. The trend of evolving coefficient of friction was found to be different for three kinds of scratch modes and the evolution of coefficient of friction has been correlated with coating deformation.
