Method of depositing a ceramic coating

摘要

A method for use with a coating process includes depositing a ceramic coating on a substrate (12) within a coating chamber (14). Prior to depositing the ceramic coating, an electron beam source (20) is used to heat a ceramic material (18). The ceramic material (18) radiates heat to heat a substrate (12) to an oxidation temperature to form an oxide layer on the substrate (12). A desired evaporation rate of the ceramic material (18) is established during the heating to thereby provide an improved ceramic coating.
