Keywords： Pt/Ru-modified

Multilayered Pt/Ru modified aluminide coating for thermal barrier coating (TBC) systems has been investigated. 2 μm Pt+2μm Ru+2 μm Pt was first deposited on nickel-base superalloy DZ125 by electrodeposition,and then the coating was treated by annealing and a conventional pack-cementation aluminizing process.The cyclic oxidation tests were carried out at 1423 K in air. It was found that the thermal cyclic oxidation resistance of Pt/Ru-modified aluminide coating was comparable to that of Pt-modified aluminide coating,which was much better than simply aluminized DZ125. The addition of Ru to Pt-modified aluminide coating increased the resistance to rumpling. The microstructures and phase constitutions of the coating before and after oxidation were investigated.
