以前実用に供されたガスタービンブレードの表面を選択的に保護する方法
Document Type and Number:
Japanese Patent JP4279105
Kind Code:
B2
Abstract:
A method for selectively protecting a gas turbine blade (20) which has previously been in service comprises the step of cleaning the gas turbine blade (20), and then first depositing a platinum first layer on the airfoil (22) and the platform (28) of the gas turbine blade (20). Thereafter, a platinum second layer is deposited over the platform (28) but not the airfoil (22). A platinum-aluminide protective coating is formed by depositing an aluminum-containing layer overlying both the platform (28) and the airfoil (22) and interdiffusing the platinum and the aluminum.
