Abstract
Operation in aggressive environmental conditions and the interaction of friction pairs impose increased demands on modern parts used in aircraft engine manufacturing and electrical power engineering. Often, working in such conditions leads to the premature failure of parts and equipment, as well as energy loss due to friction and wear processes. Advanced technologies for surface modification and coating deposition by various methods can enhance the performance characteristics of such parts. The technology of laser cladding for wear-resistant coatings, combined with preliminary surface modification, allows the creation of a protective layer on the surface and strengthens it. This paper provides an overview of modern methods for surface modification and deposition of protective coatings using various physical techniques, highlighting their advantages and disadvantages. The most promising method is the laser cladding of wear-resistant coatings with preliminary surface modification. An algorithm for the laser cladding process has been developed for this technology. The paper proposes the use of a new wear-resistant coating made from powder materials based on chromium and molybdenum carbides. The influence of the mixture composition on the properties of the synthesized coating has been determined. Adhesion strength and coating thickness have been evaluated.
