The article deals with the distribution of temperature fields in the coating of iron-based cermet in the process of laser cladding on a titanium alloy. The statement is substantiated that it is possible to apply a coating with a thickness of more than 0.3 mm on titanium in order to impart good antifriction properties to the friction surfaces, while maintaining the bulk strength properties of the titanium alloy by minimizing the thermal effect. The temperature distributions in the coating are determined by numerical modeling of the coating heating process during laser surfacing. Particular attention is paid to achieving the temperature of the titanium alloy melt. On the basis of the study, it is argued that the deposited coating will have high adhesion to the base and is efficient under friction conditions at high temperatures. The hardening technology created on the basis of the obtained technological parameters of laser surfacing will protect friction units containing titanium alloys from wear working in dry friction and high temperatures.
