| 摘 要： | 用电化学方法(EPR 法)研究了不同材料和各种敏化条件对奥氏体不锈钢敏化程度的影响,并采用摸拟贫铬区的 Fe-11%Ni-Cr(6～18%)钢,研究了 EPR 法的特性.发现对不含 Mo 的钢而言,贫铬区的铬含量在16%以下时,就发生再活化溶解,因此,EPR 法比 Strauss 法更灵敏。试验后试样表面的金相观察发现:在晶界或夹杂物周围,首先发生方向性侵蚀点,然后,连结成腐蚀沟.

| Abstract: | By means of electrochemical method (EPR method),the effects of various materials and different sensitizing conditions on sensitization degree of Austenic stainless steels are investigated,using the Fe-11% Ni-Cr(6～18%)stainless steels as simulated chromium depleted region.For stainless steels containing no molybdenum it was found that active dissolution occurs at chromuim depleted regions with less than 16% Cr.Thus EPR method is more sensitive than Stra- uss method.After the test,the surfaces of samples were examined by optical microscope.The results are as follows:as the grain boundaries or the vicini- ties of inclusions,pits are first observed with certain directions,then they join with each other to form corrosion grooves. |
