摘要: <正> 鳞爆是指搪瓷层自身产生的大小不等、深度不一的半月型剥落现象,是使搪瓷制品报废的主要原因之一。前人多认为鳞爆由氢引起。一般采用超低碳或合金化方法提高钢材储氢能力防止鳞爆。试片经电解抛光,单面镀Ni。电镀液为NiSO_4+NiCl_2,电流密度10mA/cm~2,时间1min。试片装在电解池中,池分两室。镀Ni面一侧注入0.2N NaOH溶液,施以+0.2V过电位(相对于Hg-HgO参比电极)。未镀Ni的面与一辅助电极构成电解析氢回路。生成的氢被试片吸收并向

Abstract：The tendency to fishscale on the enamel steel sheets of TC_1, 08F, 08Al, etc. has been investigated by the electrochemical H-permeation method. It showed that the fishscaling is closely related to the diffusion coefficient of hydrogen in steel. With the increase of the deformation and the Ti/C ratio of steel, the diffusion coefficient of hydrogen may be decreased and thus its tendency to fishscale may be also decreased.
