摘　　要：针对有机涂层在大气环境中失效过程较长的特点,利用Corrosion Master腐蚀仿真平台对Q235碳钢/有机涂层体系分别在海洋大气、工业大气和海洋工业大气3种腐蚀环境条件下的服役寿命进行预测,并结合腐蚀电化学相关测试与涂层的失效行为研究结果对仿真计算结果进行了分析和验证。结果表明,相同环境条件下仿真模拟计算结果与实验结果具有较好的一致性,仿真技术可以用于金属/有机涂层在大气环境下的失效行为研究,并可实现寿命预测。The degradation and service life prediction for the corrosion of organic coatings/Q235 carbon steel system in three typical environments,i.e.marine atmospheric-,industrial atmospheric-,and marine industrial atmospheric-environments,respectively were estimated by means of the corrosion master simulation platform,in terms of the characteristics of longtime failure of organic coatings in atmosphere.The simulation results were compared and verified with the corrosion electrochemical test results and failure behavior of the coating in solutions,which aim to simulate the above three environments.The results showed that the simulation results are in good agreement with the experimental results in the same environmental conditions.It follows that the simulation technology can be used to study the failure behavior of organic coating/metal systems in the atmosphere,and the life prediction can be realized.
