Abstract
The theory of conductivity of the electrolyte in a microdischarge process of oxidising of the working surfaces of products from the aluminium-based alloys is considered. Technology and technological fixture for the formation of a porous oxide coating on the surface of piston combustion chamber and a compact coating of up to 150 mm thickness and hardness up to 8 GPa on the inner surface of the cylinder are developed. The technology makes it possible to form the composite coatings with introducing dispersed ceramic particles. The offered technological fixture provides the coating formation on the working surfaces of the products manufactured from the metals used for valves.
Keywords: microarc oxidising, oxide coatings, aluminium-based alloys, technology, equipment
