电化学阻抗谱研究三种涂层体系的耐蚀性
Corrosion Resistance of Three Coating Systems Studied by Electrochemical Impedance Spectroscopy
摘 要
为选择某型特种装备的表面防腐蚀涂层,利用电化学阻抗谱对H06-4环氧富锌/H53-13环氧云铁/丙烯酸聚氨脂、环氧富锌/厚膜灰云铁环氧/TB06-42丙烯酸聚氨脂和环氧防锈平整底漆/CE-46环氧/丙烯酸聚氨脂三种涂层体系进行了耐蚀性评价测试.结果表明,随着浸泡时间的延长,三种涂层体系的保护作用都降低.对比涂层的阻抗谱变化特征得知,H06-4环氧富锌/H53-13环氧云铁/丙烯酸聚氨脂涂层体系耐蚀性较佳,因此被选为某型装备用防腐蚀涂层.

Abstract
The corrosion resistance of three anti-corrosion coating systems including H06-4 zinc rich epoxy/H53-13 micaceous iron epoxy/acrylic polyurethane coating system,zinc rich epoxy/thick film gray micaceous iron epoxy/TB06-42 acrylic polyurethane coating system and epoxy anti-rust level priming/CE-46 epoxy/ acrylic polyurethane coating system was tested by the method of electrochemical impedance spectroscopy(EIS) for the corrosion protection of some special equipment.The results indicated that the protective effect of all three coating systems was reduced with increasing immersion time.H06-4 zinc rich epoxy/H53-13 micaceous iron epoxy/acrylic polyurethane coating system had the best corrosion resistance and was selected as the anti-corrosion coating system for the equipment.
