Summary:An important part of the process of parts hardening by the induction surfacing method is the heating of hard alloy particles and flux in charge mixture. The article describes comprehensive studies on measurement and simulation of temperatures at phase boundaries in complex melting and heat-sensitive powder mixtures. To record the temperature in the induction surfacing process, it is proposed to apply CA micro-thermocouple method and the thermal indication method using SHS compositions. The developed methods for complex temperature recording in the process of induction surfacing allow to determine the melting temperature of the charge mixture and its single components.
