摘要
Indentation technique was used to characterize the mechanical proper-ties (elastic modulus, hardness and toughness) both of PVD coatings and autocatalitic chemical deposition ones. TiN and TiCN films were respectively deposited on a duplex stainless steel substrate using PVD technique; moreover a NiP films (P content about 8%) and a NiP/B4C composite ones were used as comparison materials. The effect of different substrate surface finishing (polishing and shot peening) was evaluated.
