通过高温氧化在建筑用不锈钢表面制备氧化铝膜,对其结构、形貌及硬度和抗腐蚀性能进行研究。结果表明:氧化铝层的抗腐蚀性能随着氧化时间的增加而提高。 Alumina film was prepared on the surface of stainless steel for construction by high temperature oxidation, and its structure, morphology, hardness and corrosion resistance were studied. The results show that the corrosion resistance of alumina layer increases with the increase of oxidation time.
