| 目的 解决海军直升机表面涂层体系耐腐蚀性能较差，难以满足日历寿命要求的难题。方法 采用新研制的有机涂层和原陆军直升机涂层分别对设计的结构模拟件进行涂装，并进行8个周期、共计200天的加速腐蚀试验，利用光泽度测量、色差测量和电化学阻抗测量的方法对涂层的腐蚀情况进行表征，考核验证涂层体系的防腐蚀性能。结果 试验后新、原涂层外观基本完整，新涂层光泽度与色差无明显变化，原涂层光泽度下降较大。新涂层一直处于腐蚀初期的渗水阶段，其阻抗在108Ω.cm2范围内，原涂层已进入腐蚀中期，其阻抗在106Ω.cm2范围内。结论 新涂层耐蚀性能更为优良，更加适用于海洋环境下的使用。 |

| Objective To solve the problem that the poor corrosion resistance of the naval helicopter surface coating system does not meet the calendar life requirements. Methods The designed structure specimens were painted with the newly developed organic coating and the original army helicopter organic coating. The structural part was subjected to an accelerated corrosion test of 8 cycles for a total of 200 days. The corrosion of coating was characterized by gloss measurement, loss of light measurement and electrochemical impedance spectroscopy to verify the corrosion resistance of the coating system. Results The new and original coatings were basically intact after the test, and the gloss and chromatic aberration of the new coatings were not significantly changed; and the gloss of the original coatings was greatly reduced. The new coating was always in the initial stage of corrosion; and its impedance was in the range of 108Ω.cm2. The original coating entered the middle of corrosion and its impedance was in the range of 106Ω.cm2. Conclusion The new coating has better corrosion resistance and is more suitable for using in the marine environment. |
