摘要

In this study, a finite element simulation of sliding on a diamond coating deposited on arncarbide substrate was applied to investigate dominant factors to coating delamination. Differentrnparameters including coating thickness, elastic modulus of the coating, fracture energy of therninterface, and indentation depth have been arranged for a 2-level factorial design with a constantrnload during sliding process. Minitab was employed to analyze the individual and interactionrneffects of the parameters from the simulation results. The results show that the fracture energyrnhas the most significant effect on the crack width and length. In addition, the crack width is morernsensitive to other parameters at a lower fracture-energy value. The coating elastic modulus hasrnlittle effect on the crack length and crack width. The interaction between the coating thicknessrnand the indentation depth has a dominant effect on the crack width and crack length.
