“…Considering the mentioned dependences the program of calculation of the thermal field of the system «part-coating» with the moving boundar is developed [16,17,18]. To characterize the points, the program uses an array of features, integers, depending on the value of which the choice of formulas for calculating the temperature in a particular point of the difference network is done.…”

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.
