    Abstract: The duplex coating process comprises forming an aluminide layer on the surface of Ni-base superalloy by Al-diffusion method, and vapor-deposition yttrium on diffused aluminide layer under vacuum atmosphere by ion-plating method. The process increases corrosion resistance and heat resistance of Ni-base superalloy used as material for gas turbine engine blade.

    Abstract translation: 双相涂布方法包括通过Al-扩散法在Ni基超级合金的表面上形成铝化物层,并通过离子镀法在真空气氛下在扩散的铝化物层上形成气相沉积钇。 该工艺提高了用作燃气轮机发动机叶片材料的Ni基超合金的耐腐蚀性和耐热性。
