摘　　要：用电沉积 -烧结方法在渗铝耐热钢表面制得均匀致密的Y2 O3 薄膜 ,研究其对渗铝HK4 0钢分别在 85 0℃、10 0 0℃等温氧化行为的影响 .结果表明 ,在渗铝层表面施加Y2 O3 薄膜能降低其氧化速率 .A uniform,dense and defect-free Y 2O 3 thin film was applied on the surface of aluminized HK40 steel by electrodeposition pyrolysis method.The influence of this film on the isothermal oxidation behavior of the aluminized HK40 steel,which was exposed to ambient atmosphere at 850℃,1000℃ respectively,was investigated.The results show that,by surface-applied Y 2O 3 thin film,the oxidation resistance of the aluminized HK40 steel is increased.The effects of the Y 2O 3 film on the oxidation are discussed.
