在资料[1]中,作者探讨了药皮某些组成物(如云母、萤石、大理石等)对焊缝金属扩散氢的影响作用。本文则着重探讨某些稀土金属合金及其氧化物对钢焊缝金属扩散氢含量的影响作用。我国有丰富的稀土资源,而且,储量居世界首位。稀土的一个重要化学性质,在室温下都能吸氢,温度升高时则更快,并生成稀土氢化物RH_x(x=2,3,
In [1], the author explored the effect of some components of the coating (eg mica, fluorite, marble, etc.) on the diffusion of hydrogen to the weld metal. This article focuses on the effects of certain rare earth metal alloys and their oxides on the hydrogen content of steel weld metal diffusion. Our country is rich in rare earth resources, and reserves the highest in the world. An important chemical property of rare earth, hydrogen can be absorbed at room temperature, faster when the temperature increases, and generate rare earth hydride RH_x (x = 2,3,
