| Abstract: | This paper deals with diffusible hydrogen content (H Do) of electrode deposited metal and the relationship between H D and diffusible time (H D escape characteristic). It is manifested that H D escape characteristic is influenced by many factors including diffusible hydrogen content, chemical composition, surface state. Diffusible hydrogen content (H Do) of the deposited metal can be divided into quick diffusible hydrogen(H Dq) and slow diffusible hydrogen(H Ds). |
