硫化锰夹杂溶解和微生物存在对不锈钢管的点蚀
Pitting Corrosion of Stainless Steel Pipes via MnS Dissolution and Microbial Corrosion
摘要
Abstract
The microstructure and composition of the stainless steel water tubes used for the condensers in power plants and the deposits near the corrosion holes were analyzed by SEM and EDS, respectively. The electrochemical reaction mechanism of MnS dissolution and microbial corrosion were explored, and a synergistic effect of both corrosions was found in the process of pitting corrosion. Based on the comprehensive analysis of various factors affecting the stainless-steel's corrosion, some preventive measures are put forward to help the stainless steel condensers function smoothly.关键词
