运用材料学方法确定阴极保护下限电位值

ASCERTAINMENT OF LOWER LIMIT POTENTIAL VALUE OF CATHODIC PROTECTION WITH MATERIAL SCIENCE METHOD

运用材料学方法，结合电化学测量，确定１６Ｍｎ钢－３％ＮａＣｌ水溶液体系在受力作用时阴极保护下限电位值为－９００ｍＶ（ｖｓ．ＳＣＥ）。若阴极保护电位比该值更负时，将会产生氢脆的危险。

Using the method of material science, the lower limit potential value of cathodic protection of 16 Mn steel in 3% NaCl aqueous solution under stress is found to be 900mV(vs.SCE). Hydrogen brittleness will occur if the potential is lower than this value.
