| 英文摘要: |
| A structure of gradient hard coatings (Ti, TiN, TiCN and TiAlN) is designed, and residual stress is simulated by a finite element method with ANSYS. The influence of the realistic situation including load and temperature on the residual stress of the coatings is investigated. Simulated results show that the realistic situation strongly affects the residual stress. To be specific, i) The main residual stress concentrates on the coatings prepared on YG8 substrate, and the residual stress and its gradient of the coatings are bigger than that of the substrate； ii) TiAlN and TiCN coatings have better resistance compression than that of TiN coatings in the same condition; iii) The improved multilayer structure of the gradient hard coatings produces weaker residual stress but higher anti-pressure of the substrate. |
