| 摘 要： | 目的研究不同破损程度下军绿有机涂层的腐蚀行为,确定破损率对其防护性能变化的影响。方法通过人工制作不同的破损率,并利用电化学阻抗谱技术,研究不同破损程度下军绿有机涂层的电化学特征。结果根据不同破损程度下的军绿有机涂层的电化学特征,确定了涂层从完好到失效的四个阶段,初始完好阶段(破损率K≤0.0004%)、破损增大阶段(0.0016%K≤0.04%)、破损过大阶段(0.16%K≤1%)和失效阶段(4%K≤16%)。结论破损率K为0.04%的点是该涂层防护性能急转直下的转折点,因此破损率K大于0.04%时,应及时对车辆表面涂层进行修补和防护。

| Abstract: | Objective To study corrosion behavior of military green organic coating with different damage degree, and to de-termine influences of damage degree on its protective performance changes.Methods Electrochemical impedance spectroscopy (EIS) technique was applied to study electrochemical characteristics of military green organic coating under different damage degree which were made manually.Results According to electrochemical characteristics of military green coatings under dif-ferent damage degree, four stages of the coating from good to bad were determined: initial intact stage (damage rate K≤0.0004%), increase damage stage (0.0016%
