基于多因子影响的东南沿海地区服役涂层环境试验设计

目的通过分析东南沿海地区车辆服役环境特点,提取了光照、温度、水、化学介质四种影响因素,分析四种影响因素的影响机理、影响方式、影响效果。方法对《GJB 150A—2009军用装备实验室环境试验方法》的基本运用方法及裁剪技术进行初步探讨,依据该标准制定东南沿海地区服役车辆涂层实验室试验的流程方法,并进行试验验证。结果实验室加速腐蚀试验结果与现役涂层腐蚀情况具有较好的相关性。结论为东南沿海地区涂层环境试验的设计、实施及测评,对涂层寿命预测、有效性检验和维修保养方案制定提供了重要的依据。

Design of Environmental Testing of Organic Coating Using in the Southeastern Coastal Areas Based on Multi-effects Factors

Objective To extract influencing factors of illumination, temperature, water, chemical medium and analyze the effects of the four factors from affecting mechanism, influence way and effect through analyzing characteristics of the vehicle service environment in the southeast coastal area. Methods Basic application methods and cutting techniques in GJB 150A-2009 Methods for Laboratory Test of Military Equipment were discussed preliminarily. Procedures for laboratory test on coating of vehicles serving in the southeast coastal area were determined and verified by testing. Results The results of laboratory accelerated corrosion test and corrosion of active coating had good correlation. Conclusion It provides an important basis for design and implementation of the environmental testing and evaluation of environment test for coating in the southeast coastal area, as well as prediction of service life, inspection of validity and preparation of maintenance scheme.
