模拟４００４／３００３／４００４热轧复合工艺，对４００４合金在３５０～５２５℃分别加热保温所制备的试样表面氧化情况、氧化层厚度进行了宏观分析．用电子能谱仪（ＸＰＳ）对４００４合金４７５℃下各保温时间的试样表面氧化层进行Ａｒ＋逐层溅射剥离，对剥离面进行ＸＰＳ分析．对ＸＰＳ图谱进行了计算，结果表明：４００４合金在４７５℃×３ｈ试样表面已呈深灰色，氧化已较严重；在４７５℃恒温下，４００４合金保温１～２ｈ表面氧化层增厚遵循对数曲线变化；在２～６ｈ内，表面氧化层按一定比例增长，超过６ｈ后，表面氧化层增厚有所减缓．适当降低热轧复合时的加热温度，控制４００４铝合金表面氧化层的厚度，能提高复合成功率．
The 4004/3003/4004 hot-rolled composite process was simulated to analyze the surface oxidation and the thickness of oxide layer of 4004 alloy prepared by heating and heat preservation respectively at 350-525 ℃. The oxide layer of the sample surface of the 4004 alloy at each holding time at 475 ° C was stripped by Ar + layer-by-layer sputtering using an electron spectrometer (XPS), and the XPS analysis was performed on the release surface. The XPS spectra were calculated and the results showed that the surface of 4004 alloy was dark gray and had a serious oxidation at 475 ℃ for 3h. At 400 ℃ for 4h, Curve changes; in 2 ~ 6h, the surface oxide layer according to a certain percentage of growth, more than 6h, the surface oxide layer thickening has slowed down. Appropriate to reduce the heating temperature of hot-rolled composite, control the thickness of the oxide layer on the surface of 4004 aluminum alloy, can improve the composite success rate.
