Abstract

The results on studies of the possibility of applying the technology of micro-arc oxidation as the repair and replacement technology for aluminum alloys are presented. The possibility of using technology MAO to repair and restore the geometry of the working surfaces of parts made of aluminum-silicon alloys operating at high temperatures and significant thermal deformations was displayed.
