电镀玫瑰金拉丝不锈钢制品仓储腐蚀机理研究

该文对电镀玫瑰金拉丝不锈钢制品仓储腐蚀机理进行研究分析。结果表明,电镀玫瑰金拉丝不锈钢制品腐蚀原因是拉丝后不锈钢制品表面的富铬氧化膜致密性被破坏;裂纹缝隙的存在,使得水汽和空气(含有氧气)可藏于裂纹缝隙内,为不锈钢的缝隙腐蚀提供良好的基础,从而加速电镀玫瑰金拉丝不锈钢制品腐蚀生锈。

In this paper,the storage corrosion mechanism of electroplated rose gold brushed stainless steel products was studied and analyzed.The results show that the corrosion of electroplated rose gold drawing stainless steel products is caused by the destruction of the compactness of chromium-rich oxide film on stainless steel products surface after drawing,and the existence of cracks makes water vapor and air(containing oxygen)hidden in the cracks,which provides a good basis for the crevice corrosion of stainless steel,so as to accelerate electroplated rose gold brushed stainless steel products corrosion and rust.
