日本佐贺县工业技术中心对成为金属材料脆性破坏原因的金属中的扩散性氢进行分离和分析取得了成功,有了解释清楚防止氢脆的希望。 氢脆是螺栓、弹簧等在洗净、电镀过程中因导入氢而使材料强度大大降低的现象,该中心注目于金属中含有的两种氢中与脆性破坏有关的扩散性氢,仅将这种扩散性氢 Japan’s Saga Prefecture Industrial Technology Center succeeded in separating and analyzing diffusible hydrogen in metals that are responsible for the brittle failure of metallic materials, with the hope of explaining hydrogen embrittlement prevention. Hydrogen embrittlement is the phenomenon that materials such as bolts and springs are drastically reduced due to the introduction of hydrogen during the cleaning and electroplating process. The center focuses on diffusible hydrogen related to brittle fracture in two kinds of hydrogen contained in the metal, Diffusion of hydrogen
