钢在熔铸、热处理、焊接、电镀过程中会有氢渗入,氢能诱发裂纹,使塑性降低,致使材料提前断裂。确定材料氢脆方法有物理检测法、化学检测法和力学检测法三类,物理检测法利用氢渗入材料加热后氢能释放的原理来确定材料渗氢的程度和速率,有压力氢探测仪、真空氢探测仪和劳伦斯测氢仪等,真空氢探测仪和劳伦斯测氢仪由于价格昂贵应用受到限制,后者在航空工业中已得到应用。
Steel in the casting, heat treatment, welding, electroplating process will have hydrogen infiltration, hydrogen can induce cracks, so that plasticity, resulting in premature fracture of the material. Hydrogen embrittlement method to determine the physical detection method, chemical detection method and mechanical detection of three types of physical detection method using hydrogen permeation of hydrogen heating material after the release of the principle to determine the extent and rate of hydrogen permeation material, there are pressure hydrogen detector, Vacuum hydrogen detector and Lawrence hydrogen detector, vacuum hydrogen detector and Lawrence Hydrogen instrument due to expensive applications are limited, the latter has been in the aviation industry has been applied.
