摘要
生产现场发现水基乳化液润滑冷轧铝及铝合金板,沿着轧制方向板材边缘的上、下表面几乎对应地出现明显的白色腐蚀条纹。试验以冷轧1100纯铝板为研究对象,采用SEM,XPS等测试分析手段对其表面腐蚀成分及腐蚀机理进行研究。试验研究结果表明,铝材腐蚀面的成分是AlOOH。
The water-base emulsion is used on aluminum cold rolling mill. White corrosion stripes have been found by cold-rolled aluminum strip edges both on the upper and under surfaces. The stripes are along the roiling direction. The surface corrosion composition and corrosion mechanics of 1100 aluminum cold roiled strip have been analyzed by scanning electron microscope and X-ray photoelectron spectroscope. The results show that the corro- sion substance of the aluminum strip is A100H.
