Abstract
The high temperature properties of protective coatings, paricularly the oxidation resistance, is improved by the melting of a surface portion of the coating using a high intensity energy source. The surface melting refines and homogenizes the coating structure, thereby eliminating defects which would otherwise cause premature coating failure.
