“…Tilbrook et al [4] reported micostructural effects on indentation failure mechanisms in TiN coatings by finite element simulations. Romankova et al [5] studied the effect of annealing treatment on the structure and properties of the nanograined TiN coatings produced by an ultrasonic coating process. With an increasing demand for industrial practice, further investigation of multilayer coatings in the feature of the improved wear resistance, hardness, and higher oxidation resistance with modulation of different phases has attracted much attention in the past few years [6][7][8].…”
