Summary:Metal matrix composite type layers produced by concentrated energy beam processing show a series of features influenced by the manner of application and the thermal properties of the added materials. This paper discusses the laboratory research results regarding the production SiC-Cu alloy and WC-steel type composite layers under the conditions of electrochemical codepositing of the added materials (SiC-Cu, WC-Co) prior to laserbeam processing. Composite layers possess load carrying capacity and wear resistance greater than the base materials prior to implantation, thus leading to increased lifetime in friction applications.
