Laser Metal Deposition (LMD) process and some other modifications of additive manufacturing such as DED, DMD, LENS®, etc. are related for LC processes. These processes can be used for producing blisks and blings, i.e. in hybrid processes. Recent trends in the development of new-generations gas turbines are associated with an increase turbine outlet temperature. One of the ways to respond to the technological challenges arising from this is the development of new alloys resistant to high temperatures. The use of Ni-based superalloys with admixture of rhenium, rare-earth and other elements provides the necessary resistance at high temperatures. However, in the process of laser restoration of blades from these materials, it is important to form a certain microstructure, to avoid the formation of undesirable phases, to reduce the heat-affected zone and residual stresses, to prevent cracking and improve the characteristics of the blades. The article describes the developed mathematical model of heat exchange during laser restoration of turbine blades. The model allows one to calculate the distribution of temperature fields in a material depending on changes in the radiation power and the scanning speed of the laser beam. Various exposure options for reducing of the heat affected zones on the basis of changes in the laser cladding parameters are discussed. The heat exchanger was modeled as a special tool for cooling in the LMD/LC processes
