Abstract
The strength of the Al2O3 powder coating formed by a cumulative detonation method on a steel St3 substrate is determined, and its structure is studied. The optimum conditions for deposition are chosen. They make it possible to form a dense high-strength coating with good adhesion to the substrate.
