The relevance of the stated topic of scientific research is conditioned by the need to obtain qualitative substantiation of the optimal powder mixture with a large number of components, to get the best effect when solving practical problems using methods of laser restoration of working surfaces of parts. This research work aims to justify the optimal structure of a multi-component pulverulent composition for laser restoration of damaged working surfaces of parts. The methodological approach in this scientific research is based on a combination of systematic research of main peculiarities of the process of obtaining high-quality working coating of the part with practical research of possibilities to increase the quality of part coating using pulverulent compositions of many components, which supposes the practical application of a range of research methods to determine real quality parameters of the final coating. In the course of research operations, the results were obtained, that show the possibility of reducing to a minimum the changes in the configuration of the part and the value of its internal stresses, as well as the transfer of necessary characteristics, especially hardness and wear resistance, through the implementation of developed multi-component pulverulent compositions. The results obtained during the investigation of prospects of justification of optimal mix of multi-component pulverulent compositions for laser restoration as well as conclusions formulated on their basis have essential practical importance for workers of chemical and metallurgical industries.
