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。
By means of material science and electrochemical measurements, the lower limit of cathodic protection potential of 16Mn steel-3% NaCl aqueous solution was determined to be -900mV (vs.SCE). If the cathodic protection potential is more negative than this value, there is a danger of hydrogen embrittlement.
