E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.Abstract
Temperature fields of surface layers during the process of plasma-detonation treatment of parts were determined on the basis of solving the noil-stationary equation of thermal conductivity by the finite difference method. The resulting calculation dependencies were used to analyse kinetics of phase transformations in structure of steel U8 during PDT.
Keywords: plasma-detonation treatment, carbon steels, absorbing coatings, process parameters, metallography, X-ray phase analysis
