我国东南沿海车辆装备涂层环境试验设计

目的研究我国东南沿海环境对我军车辆装备涂层的影响。方法根据近海试验场所提供的温湿度、氯离子浓度、辐照总量等相关数据,当量转化为光照、温度、湿度、化学介质四种环境因子,依据GJB150A—2009《军用装备实验室环境试验方法》裁剪制定了依次进行湿热辐照试验、中性盐雾试验和酸性盐雾试验的实验室模拟方法。结果相同试片在实验室模拟环境与实际环境中表现出的电化学特征较为一致。结论该试验设计能较好模拟当地实际环境影响,为在该地区服役的车辆装备有机涂层的使用寿命预测、涂层防护与防腐蚀保养等技术研究提供了重要依据。

Environmental Test Design of Vehicle Equipment Coating in Southeast Coast of China

Objective To study impacts of southeast coastal environment of China on coating of military vehicles. Methods Relevant data such as temperature, humidity, chloride ion concentration, and total irradiation provided by offshore test sites were converted to specific values of light, temperature, humidity, and chemical medium. According to the GJB 150A-2009 Military Equipment Laboratory Environmental Test Method, the whole test was cropped to carry out wet heat radiation test, neutral salt spray test, and acid salt spray test. Results The result of the electrochemical characteristics in the laboratory simulation environment was consistent with the result in the actual environment. Conclusion The design simulates the actual environmental impact of the local area quite well and provides an important basis for life prediction of organic coatings, coating protection, and anti-erosion in the region.
