研究了用于热障涂层(TBC)系统的多层铂/Ru改性铝化物涂层。采用电沉积法在DZ12 5镍基高温合金表面沉积2μm Pt+2μm Ru+2μm Pt，然后对镀层进行热处理和常规的渗铝处理。在1423K的空气中进行了循环氧化试验。结果表明，PtRu改性铝化物涂层的抗热循环氧化性能与Pt型铝化物涂层相当，远优于单纯渗铝的DZ125涂层。在铂改性铝化物涂层中添加Ru，提高了涂层的抗皱性。研究了涂层氧化前后的组织和物相组成。
Multilayered Pt/Ru modified aluminide coating for thermal barrier coating (TBC) systems has been investigated. 2 μm Pt+2 μm 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.
