| Abstract: | 7Cr13-Zn composite coating has advantages such as high strength and hardness and small shrinkage that is suitable for rapid arc spraying tooling technology.The effect of arc spray parameters on the performance index like the coating strength,porosity and wearability were studied through orthogonal test and an optimal combination was obtained.The application of the optimized 7Cr13-Zn composite coating to rapid tooling improves the performance of the moulds. |
