鋼中水素のモニタリングへの電気化学的水素透過法の適用

抄録

There are several degradation phenomena when hydrogen enters into steels, i.e., hydrogen induced cracking, hydrogen embrittlement and hydogen attack, whick are occurred depending on the strength of steel and temperature of environment. The hydrogen monitoring methods proposed by Prof. Yamakawa using an electrochemical hydrogen permeation technique to predict the degredation of steel and actual monitoring results are reported here.
