Abstract
A method for forming a thermal barrier coating system on a turbine engine component includes forming a bondcoat on the turbine engine component and depositing a thermal barrier coating so as to overlie the bondcoat. The bondcoat is formed by thermally co-spraying first and second distinct alloy powders on the turbine engine component forming an oxidation-resistant region, and thermally spraying a third alloy powder on the oxidation-resistant region to form a bonding region. The oxidation-resistant region is more resistant to oxidation than the bonding region
