摘要
用动电位扫描、X-射线衍射和扫描电镜研究了高硅奥氏体不锈钢在 93% H2 SO4、95 % H2 SO4和 10 % Fe Cl3介质中的腐蚀行为。结果表明 ,含有高硅的奥氏体不锈钢其耐蚀性能均得到提高 ,主要是因为硅的加入改善了不锈钢的钝化性能 ,加快了不锈钢在介质中由活化状态到钝化状态的转变。
This paper studied on the corrosion behaviers of high silicon austenitic stainless steel in 93% H2SO4, 95% H2SO4 and 10% FeCl3 solutions by using XRD and SEM. The results showed that the austoritic stainless steel with silicion higher corrosion resistance. It was attrituted to the silicon additives could quicken stainless steel from active state to passive state, there fore improved the corrosion resistance of stainless steel.
