Abstract:
A method for preparing a nickel-base superalloy article protected by a thermal barrier coating, comprising the steps offurnishing a substrate made of a nickel-base superalloy; thereafter depositing a bond coat layer overlying and contacting the substrate; thereafter removing any oxide formed on the bond coat layer; thereafter depositing a ceramic layer overlying and contacting the bond coat layer, thereby forming a coated substrate; thereafter placing the coated substrate into a heating apparatus operating with an oxidizing atmosphere and an oxygen partial pressure; and thereafter heating the coated substrate in the heating apparatus to a temperature of from about 1850Â° F. to about 2100Â° F., for a time of at least about 30 minutes to form a final article; and thereafter placing the final article into service in a jet engine.
