Study on the Residual Stress of SiCp/Cu Gradient Coating by Laser Deposited
The residual stresses of SiCp/Cu gradient coating by laser deposited are simulated using finite element software ANSYS. The finite element analysis model of the gradient coating is established. The residual stresses of SiCp/Cu gradient coating are discussed based on the gradient distribution factor and the single layer thickness. The results show that the larger residual stresses are mainly distributed on the interface edge between the gradient coating and substrate. When the layer number is 4, the gradient distribution factor is 1, and the single layer thickness is 0.6 mm, the residual stress relaxation of SiCp/Cu gradient coating is excellent. SiCp/Cu gradient coating with clear interfaces and excellent combination between the different gradient layers is prepared by laser deposited based on the optimization results. Compared with the homogeneous coating, the hardness and wear resistance are increased by 23.2% and 5.2%, respectively.
