通过电位探头曲线扫描方法及电化学测量技术,探讨了碳钢及低合金钢的焊接接头在海水中耐蚀性能,低合金钢的局部腐蚀倾向比碳钢严重,而耐均匀腐蚀性能则优于碳钢低合金钢的焊接接头选择性腐蚀主要集中于焊缝区,其原因是由于该区出现了铁素体带,加速了局部腐蚀
The corrosion resistance welded joints of a low-alloy steel and carbon steels in sea water has been investigated by means of the micro-probe potential-scanning method and electrochemical techniques.The results show that the localized corrosion of the low-
