摘　　要：对Ｎｉ－ ９Ｃｒ－１Ａｌ 铸态合金及其溅射纳米晶涂层进行了９００ ℃为时２００ ｈ 恒温氧化实验，结果表明：铸态合金及溅射涂层都生成了由Ｃｒ２Ｏ３ 和Ａｌ２Ｏ３ 组成的外氧化物．通过断面观察发现两者都发生了内氧化现象．讨论了溅射涂层内氧化发生的机制．The investigation of the isothermal oxidation behavior of cast and sputtered Ni-9Cr-1Al coating in air at 900 ℃ for up to 200 h indicates that Cr 2O 3 and Al 2O 3 external oxide scale were formed on cast Ni-9Cr-1Al alloy and sputtered Ni-9Cr-1Al coating after 200 h oxidation. The internal oxidation are observed in both of them. The internal oxidation of sputtered Ni-9Cr-1Al was evaluated.
