本文用Ａｕｇｅｒ电子能谱（ＡＥＳ）、Ｘ射线光电子能谱（ＸＰＳ）、二次离子质谱（ＳＩＭＳ）及耐腐蚀磨损性能试验（ＣＷＴ）等方法，对５４５４铝镁合金管与工业纯铝管在碳化液介质中形成的表面膜进行了研究．结果表明：两种合金管表面膜的主要成分均是铝的水化氧化物；表面膜愈薄，耐蚀性愈好；５４５４铝镁合金管的耐腐蚀磨损性能较工业纯铝管有很大提高，这是由于合金元素Ｍｇ的强化作用所致；其表面膜中Ｍｇ￣＋计数比基体高两个数量级以上．
In this paper, 5454 aluminum-magnesium alloy tube and industrial pure aluminum tube were used in the test of Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS), secondary ion mass spectrometry (SIMS) and corrosion resistance wear test (CWT) The surface films formed in the carbide medium were studied. The results show that the main components of the surface films of the two alloy tubes are all hydrated oxides of aluminum. The thinner the surface film is, the better the corrosion resistance. The corrosion resistance of 5454 aluminum-magnesium alloy tube is much higher than that of pure aluminum tube Increase, which is due to the strengthening effect of the alloying element Mg; the Mg ~ + count in the surface film is more than two orders of magnitude higher than that of the substrate.
