“…We consider the fact that the deformation rate at the thermal field change during deposition is not so high to cause large thermal sources as a result of inner friction, which can change thermal field of the investigated system «coating-base». On the basis of nonlinear nature of the assigned task, search for solution is done by numerical methods [5,6], at that the thermal problem is solved by the finite differences method, and the structural problem -by the finite element method [7,8].…”

The method to determine thermal fields considering dependence of thermophysical and mechanical properties of coating materials and a base from the temperature, the running of plastic deformations and stresses relaxation at plasma spraying is suggested. The mathematical model of calculation of thermal field with moving boundary considering nonlinear feature of coating growth at layer-by-layer deposition and dependences from thermophysical properties of materials of the system «coating-base» is developed. The model application helps to estimate the effect of the parameters of plasma spraying process on the level of the residual stresses in the increased coatings.
