This specification covers the engineering requirements for applying aluminum oxide to metal parts by detonation deposition and the properties of such coatings.This process has been used typically to provide a hard, wear-resistant surface on metal parts, particularly those used under corrosive or elevated-temperature oxidizing conditions, but usage is not limited to such applications. This coating is not recommended for surfaces with deep vee-shaped grooves, blind cavities, narrow holes, or sharp corners, or where deformation of the basis metal may be expected.
