摘要
采用酒精法测量扩散氢 ,研究了焊条熔敷金属扩散氢含量以及在测氢过程中扩散氢逸出量与逸出时间的关系 (逸出特性 )。研究结果表明 ,熔敷金属扩散氢逸出特性受扩散氢含量、焊道数、熔敷金属化学成分和表面状态等多种因素的影响。熔敷金属扩散氢 (HDo)可以分为快速逸出扩散氢 (HDq)和慢速逸出扩散氢(HDs)
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).
