车辆装备有机涂层腐蚀的EN参数分析

Analysis of EN Parameters in Vehicle Equipment Organic Coating Corrosion

模拟沿海自然环境设计了军绿有机涂层在紫外线、盐雾交替环境下的腐蚀实验,用EN技术对结果进行了分析。选择电位噪声信号极差为研究对象,对比了不同周期极差与初始状态极差的变化情况。结果表明,军绿有机涂层在40天之后进入快速腐蚀阶段,64天之后极差变小。极差作为衡量噪声振幅的参数之一,可以在一定程度上反映出军绿有机涂层的腐蚀状况。

Designing the corrosion experiment of the military green organic coating in the environment of ultraviolet and salt spray,and analyzing the results by electrochemical noise technique. The potential noise signal was chosen as the object of study,and the variation between the different period and the initial state was compared. The results showed that the military green organic coating came into the rapid corrosion stage after 40 days,and 64 days later,the range became very small. As one of the parameters to measure the amplitude of the noise,to a certain extent,range can reflects the corrosion of military green organic coating.
