摘要

采用在碳钢表面复合沉积Ni-CeO2扩散渗铝的方法

得到了CeO2改性的复合渗层

在H2S溶液腐蚀条件下对渗层进行了耐腐蚀性能试验研究

并利用SEM对渗铝层的显微组织进行了分析。结果表明

经CeO2改性渗铝的方法获得了富集CeO2的细晶层

同时

渗层的耐H2S腐蚀性能明显提高

腐蚀质量增量为纯铝渗层的40%。

Abstract

A CeO2-modified aluminized coating has been fabricated by compound electro-deposition Ni-CeO2 and aluminization method on carbon steel. The corrosion resistance of the CeO2-modified aluminized coating in H2S solution was examined

and the microstructure of the coating was observed by SEM （scanning electron microscope）. The results indicate that the enriched CeO2 fine grain layer can be created in the CeO2-modified aluminized coating

obviously improving the corrosion resistance of the coating in H2S solution

which is 2.5 times higher than that of aluminized coating.
