本文首次应用多弧离子镀技术沉积Ａｌ２Ｏ３保护性氧化膜形成类型的ＮｉＣｏＣｒＡｌＳｉＹＨｆ涂层和 ＣｏＮｉＣｒＡｌＴａＹ涂层，探讨了涂层质量和沉积工艺的关系，对两涂层的高温氧化性能和热腐蚀性能进行了试验研究，分析了涂层的高温防护衰退机制．
In this paper, the first type of NiCoCrAlSiYHf and CoNiCrAlTaY coatings were deposited by multi-arc ion plating to form the protective oxide film. The relationship between the coating quality and the deposition process was discussed. The high temperature oxidation performance and hot corrosion resistance Experimental study, analysis of the coating of high temperature protection recession mechanism.
