Abstract

Methods for obtaining aluminum materials modified with silicon carbide particles were studied. The oxidation resistance of silicon carbide in an aluminum matrix was examined under microarc oxidation in an electrolyte based on boric acid. A protective composite-based silicon-containing oxide coating was obtained with low porosity and microhardness of up to 9.0 GPa.
