| 摘要 |
A method of forming a thermal barrier coating on a turbine component is disclosed. The method comprises first depositing a bond coat on the turbine component. A dispersion strengthened ceramic layer containing boride particles as dispersoids is formed on the bond coat layer by plasma deposition. Ceramic coated boride particles comprise the plasma deposition feedstock in order to disperse the boride particles in the ceramic layer. The dispersion strengthened ceramic layer includes at least one of yttria-stabilized zirconia, rare earth stabilized zirconia, rare earth stabilized hafnia, and rare earth stabilized titanate.
