The analysis of the technology for obtaining deposited by melting wear-resistant layers is carried out and the main disadvantages that reduce the operational characteristics are noted. The possibility of scientific substantiation for the choice of the processing temperature and the required concentrations of the initial elements of multicomponent systems by calculating eutectic temperatures and concentrations, as well as by constructing schema of diagrams of multicomponent systems is shown. The choice of the optimal melting temperatures of continuous or discrete layers reduces energy costs and determines the phase composition of the layers and their operational properties.
