碳钢及环氧清漆在不同溶液中的半导体导电行为
Semiconducting Behavior of Carbon Steel and Epoxyresin Varnish in Different Solutions
摘 要
采用电位-电容法结合Mott-Schottky分析技术研究了自腐蚀电位条件下20号碳钢及涂层体系在酸、碱和盐溶液中的半导体导电行为.结果表明,在不同的腐蚀溶液中,随着时间和扫描电位的增加,20号钢空间电荷层电容(Capacitance of space charge layer,Csc)变化规律不同.20号碳钢在5%硫酸溶液和5%硫酸钠溶液中呈现p型半导体导电特征,而在5%氢氧化钠溶液中,20号钢表面形成了两个空间电荷层结构,呈n型半导体特征.环氧清漆在不同电解质溶液中也表现出半导体导电特征,出现由绝缘态向半导体态转变的现象.

Abstract
The semiconducting behavior of 20 carbon steel in acid,alkali and salt solutions was studied by utilizing potential-capacitance and Mott-Schottky analysis methods.The results showed that the capacitance variation of space charge layer of 20 carbon steel in different solutions methods was different.The carbon steel showed p-type semiconducting behavior in 5% sulfuric acid and 5% sodium sulfate solution.However,the carbon steel showed n-type semiconducting behavior in 5% sodium hydroxide and formed two space charge layers.The epoxy resin varnish showed semiconducting behavior in different electrolyte solutions and exhibitea transformation from insulating state to semiconducting state.
