ELECTROEXPLOSIVE SPUTTERING OF WEAR-RESISTANT COATINGS OF THE TiC – Mo SYSTEM AND STUDY OF THEIR STRUCTURE
Abstract
Composite coatings of the TiC-Mo system exhibit high wear resistance and microhardness. These coatings are currently formed using plasma spraying in air and vacuum. Composite coatings are used in mechanical engineering to protect components subject to increased loads when operating in aggressive environments and at high temperatures, particularly in piston systems of automotive internal combustion engines. However, the structure of these coatings has several drawbacks, such as porosity (which impairs the coating's thermal conductivity) and poor adhesion to the substrate.
