| 摘 要： | Zn2+对304L不锈钢钝化膜半导体性能的影响目前鲜见报道.利用电容测量法研究了304L不锈钢在一系列ZnSO4浓度溶液中所形成的钝化膜的半导体性能,同时对影响钝化膜半导体性能的因素进行了讨论.考虑SO24-对不锈钢钝化膜的影响,在相同温度和浓度的条件下进行了Na2SO4中的浸泡对比试验.结果表明:在电位小于-0.4 V内,膜呈p型半导体特性,电位处于-0.4～0.3 V内,膜呈n型半导体特性;随着测试温度的升高及Zn2+浓度的增加,Mott-Sclaottky曲线的斜率有增大的趋势,膜内的杂质浓度减小.

| Abstract: | The semiconducting performance of the passivation films on 304 stainless steel,prepared from a series of ZnSO4 solution with different concentrations,was investigated by measuring the electric capacity.At the same time,by taking into account the effect of SO42-on the passivation films on stainless steel,comparative im-mersion tests in Na2SO4 solution were conducted at the same tem-perature and concentration.This aims at revealing the factors af-fecting the semiconducting performance of the passivation films... |
