中文摘要:
      采用阴极等离子电解沉积弥散Pt颗粒增韧YSZ-Pt/Al2O3-Pt双层复合涂层。涂层中弥散的Pt颗粒阻碍的氧在涂层中的扩散,提高了涂层的抗氧化性能。Pt颗粒的弥散增韧显著提高了涂层的断裂韧性,缓解了陶瓷层与合金基体在高温下产生的热应力,使得涂层在高温服役过程中具有良好的抗剥落性能。

英文摘要:
      In this study, Al2O3-Pt/YSZ-Pt double layer composite coatings were prepared by cathode plasma electrolytic deposition (CPED) on the high-temperature alloy with a NiCoCrAlY bond-coat. The composite coatings were consisted of a Al2O3-Pt film and a YSZ-Pt top-coat, and showed a good adhesion with the metallic bond-coat. It is demonstrated, from the cyclic oxidation test and mechanical properties test, that such coatings possess good oxidation and spallation resistances. These beneficial results can be attributed to the effects: such coatings can inhibit further oxidation of the bond-coat owing to the extremely low oxygen diffusion rate of Al2O3-Pt film; the mechanical properties of Al2O3-Pt/YSZ-Pt composite coating are improved by the toughening effects of Pt particles.
