俄罗斯国家科学中心库尔恰托夫研究所最近研究出一种新方法 ,可准确有效地检测出金属材料表面存在的微小裂纹。这种新方法的特点是通过检测金属表面氢的含量来发现微小裂纹。由于氢具有容易穿入金属缝隙的特性 ,通过测量金属材料表面附近氢的含量 ,即可判断出金属表面是否存在 The Kurchatov Institute of Russia’s National Science Center has recently developed a new method that accurately and effectively detects the presence of tiny cracks on the surface of metallic materials. The new method is characterized by the detection of metal surface hydrogen content to detect micro-cracks. Because hydrogen has the property of easily penetrating the metal gap, the presence of the metal surface can be judged by measuring the content of hydrogen in the vicinity of the surface of the metal material
