一、概 述 电镀时零件上总是或多或少伴随有氢的析出。其中,大部分被还原的氢原子会复合成氢分子从零件表面以气泡逸出,但也有一部分会渗入金属内部。正是这一部分氢会引起材料的氢脆破坏。 关于氢脆试验方法的研究已有大量文献报导,但大都是各种机械试验方法(如缺口拉伸,弯曲条,C形环,O形环等)。人们希望有一种快速的简单的试验方法。关于氢含量的分
First, an overview of parts of the plating is always more or less accompanied by hydrogen precipitation. Among them, most of the reduced hydrogen atoms will be combined into hydrogen molecules from the surface of the bubble to escape, but also some will infiltrate the metal inside. It is this part of the hydrogen can cause hydrogen embrittlement destruction of the material. A great deal of literature has been reported on the research of hydrogen embrittlement test methods, but most of them are all kinds of mechanical test methods (such as notched tensile, curved strip, C-ring, O-ring, etc.). People want a quick and easy test method. About hydrogen content of the points
