摘要
采用环氧煤沥青作为涂层材料,测定了涂敷不同厚度涂层的Q235钢的交流阻抗谱。结果表明,随着涂层厚度的增加,涂层电阻和极化电阻都得到提高,涂层抗电解质溶液侵蚀能力增强,从而减缓了金属基体的腐蚀进程。
EIS of Q235 steel with epoxy coal tar coating was determined. It is shown that the infiltrative electrolyte amount into coating decreases with increasing coating thickness. The electric resistance and polariziation resistance of the coating increase with increasing the thickness, which retards the corrosion of Q235 steel.
