摘要
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.
