1.前言 我们把含Cr为12wt％以上的钢定义为不锈钢,它具有优良的耐均匀腐蚀性,这样不用说用它制造像餐具等接触淡水的家庭用品,而且也能广泛应用于化学工业中接触高腐蚀环境的结构材料或装置材料。但是有的报告指出,在氟及氟化物环境中应用不锈钢,由于与环境中含有的金属产生高反应而导致不锈钢腐蚀的事件发生。 本文结合实例概述由氟和氟化物造成的不锈钢腐
1. INTRODUCTION We define stainless steels containing 12% by weight or more of Cr as stainless steel, which has excellent resistance to uniform corrosiveness so that it can be used as household products such as tableware to contact with fresh water, but also widely used in the chemical industry Structural materials or device materials that come into contact with highly corrosive environments. However, some reports point out that the use of stainless steel in fluorides and fluoride environments causes corrosion of stainless steel due to high reaction with the metals contained in the environment. This article summarizes stainless steel rotors caused by fluorine and fluoride with examples
