摘要:

采用双电解槽氢渗透法研究了表面镀镍与否、试样厚度、充氢溶液中硫脲含量和充氢电流密度等各种因素对扩散系数的倒数TH值的影响。结果表明，表面粗磨、不镀镍，也能测出稳定的TH值。当试样厚度d从0.25 mm增至0.6 mm，TH值线性下降；d≥0.6 mm 后，TH值保持不变。升高电流密度、增加硫脲含量均使TH值下降。

关键词 ：搪瓷钢, 鳞爆, 氢渗透, TH值

Abstract：

Hydrogen-induced fish-scaling resistance got better as hydrogen diffusion coefficient of enamelled steel sheet D decreased, which is inversely proportional with the TH value. The main objective of this work was to study the effects of certain variables such as nickel-plating or not, sample thickness, promoter concentration and charging current on TH value. The results showed that no-nickel-plating for sample surface did not influence the stability of TH value. If sample thickness d increased from 0.25 mm to 0.6 mm, TH value decreased linearly. TH value kept invariant when d ≥ 0.6 mm. TH value decreased with the increase of charging current density and promoter concentration.

Key words：
enamelled steel sheet fish-scaling hydrogen permeation TH value
