紀要論文 大気腐食環境下における鉄鋼材料中の透過水素の 表面電位分布測定による可視化

勝村, 俊規

内容記述
It is important to evaluate behavior of hydrogen penetration and permeation caused by corrosion reaction. Some methods such as thermal desorption methods and electrochemical methods can give information for the amount of permeated hydrogen. However, it is difficult to obtain the distribution of hydrogen permeation.In this study, the possibility of the visualization by surface potential measurement was investigated. It was implied that hydrogen produced by corrosion reaction would affect surfacepotential and permeated hydrogen could be visualized as surface potential distribution.Key Words: steel, corrosion reaction, hydrogen permeation, surface potential
