摘要	用电弧离子镀方法在1Cr11Ni2W2MoV不锈钢表面制备Ti0．7Al0．3N涂层,研究了涂层在450℃空气中恒温氧化行为和在固态NaCl和水蒸气综合作用下的腐蚀行为．结果表明：Ti0．7Al0．3N涂层在空气中均具有优良的抗氧化能力,而不锈钢在固态NaCl和水蒸气综合作用下的腐蚀严重,施加Ti0．7Al0．3N涂层显著地提高了不锈钢基体的抗腐蚀性能．1Cr11Ni2W2MoV不锈钢由于生成内层富Cr,外层富Fe的疏松氧化物,其在固态NaCl和水蒸气综合作用下发生严重的腐蚀,而Ti0．7Al0．3N涂层生成致密的Al2O3和TiO2的混合物,使其具有良好的抗氧化和腐蚀性能．
其他摘要	A Ti0.7Al0.3N coating was deposited on 1Cr11Ni2W2MoV stainless steel by arc ion plating. The oxidation behavior in air and corrosion resistance under NaCI deposit in wet air at 450 ℃ of the coating were investigated. The results show that the Tio.T0.7Al0.3N coatings exhibited excellent oxidation resistance in air at 450℃, severe corrosion happened to the stainless steel, while a great enhancement in corrosion resistance occurred to the substrate with Ti0.7Al0.3N coatings. The porous oxides with inner layer rich in Cr and outer layer rich in Fe formed on the 1Cr11Ni2W2MoV stainless steel, while dense oxides mixture of Al2O3 and TiO2 appeared to the coatings after corrosion which greatly inhibited the inwards diffusion of O and HCI and enhanced the corrosion resistance. The mechanism of the effect of water vapor and NaCI on corrosion of Ti0.7Al0.3N coatings was proposed.
