By analyzing the governing factors of residual stress in Plasma Spray process, the calculating model of residual stress was suggested based on an adding/removal model. Based on this model, we draw two conclusions: (1) The maximum residual stress is located mainly near the coating-substrate interface (2)Added coating layers can effectively reduce the residual stress.
