用ASTM-G48标准研究了氢对310不锈钢点蚀的影响。对于不充氢的样品,经过6天的时间也不发生点蚀,而对于预充氢的样品,几分钟后就有大量点蚀。点蚀的密度和大小均随着氢含量的增加而增加。点蚀坑的直径D与浸泡时间t的对数呈直线关系:D=αlnt+β。α值随氢含量增加而增大。
The effect of hydrogen on the pitting corrosion of 310 stainless steel was studied using the ASTM-G48 standard. Pitting corrosion did not occur for 6 days for non-hydrogenated samples, whereas for pre-hydrogenated samples a large number of pitting occurred after a few minutes. Pitting density and size increase with increasing hydrogen content. Pitting pit diameter D and soaking time t logarithm of a linear relationship: D = αlnt + β. Alpha value increases with increasing hydrogen content.
