An important component of the process of hardening parts by induction surfacing is the heating of hard alloy and flux particles in the surfacing charge. The article describes complex studies on measuring and modeling temperatures at phase boundaries in complex melting and thermoreactive powder mixtures. To register the temperature in the process of induction surfacing, it is proposed to use the XA-microthermocouple method and the method of thermal indication using SHS compositions. The data of numerical modeling and solution of the non-stationary problem of heat conduction in the selected model of composite contact materials are presented. The developed methods of complex registration of temperature in the process of induction surfacing make it possible to determine the melting temperatures of the surfacing charge and its individual components, as well as the surface of the part.
