摘要: 本文作者应用自行研制的激光过滤式测氢仪,测量了钢中的氢分布。结果表明:ⅰ)钢中的本底氢为常数。相对氢指数D_H可以表征微区氢浓集程度:ⅱ)钢中氢分布随渗氢时间和表面距离而改变:ⅲ)焊接接头中氢分布状态,受基体组织和应力的影响。本仪器激光轰击点直径为20μm。上述结果表明该方法可以较为满意地用来测量钢中微区的含氢量.

Abstract：The hydrogen distribution in metals can be measured by means of laser hydrogeh detector set up in the authors' laboratory. The results show: 1. Relative hydrogen index D_H may be used to indicate relative content of hydrogen, with consfant background hydrogen in steel 2. The hydrogen content is related to the time of hydrogen penetration and the distance between the surface and the point measured; 3. The measurement of the hydrogen distribution in various welded joints shows that such distribution varies with time. Our practice proves that the hgdrogen detector set up in our laboratory can be used to measure local hydrogen distribution in metals.
