中文摘要:
      目的 考核评价高原环境下服役的直升机旋翼桨叶典型结构及其防护体系的耐腐蚀性能。方法 利用建立的模拟高原环境加速试验谱， 再现直升机旋翼桨叶结构防护体系实际服役过程中出现的腐蚀损伤， 采取电化学阻抗谱测试研究涂层阻抗的变化。结果 经历8个周期的户内加速试验后， 新修桨叶试验件表面有机涂层Bode曲线呈现小幅下降， 即有机涂层防护性能下降； 报废桨叶试验件表面有机涂层的特定频率电化学阻抗模值与原始情况相比仅下降了不到1个数量级。结论 报废桨叶试验件表面有机涂层电化学阻抗模值曲线在8个周期后仍然小幅高于未经历户内加速试验的新修桨叶试验件。
英文摘要:
      Objective To evaluate the anti-corrosion properties of typical helicopter rotor blade structure and its protection system that services in plateau environment. Methods Accelerated testing spectra for simulation of plateau environment was employed to reproduce the corrosion damage in service condition. Electrochemical impedance measurement was used to study the degradation of impedance of organic coatings. Results After 8 cycles of indoor accelerated testing, the EIS Bode diagram of the organic coatings on the repaired blade specimen decreased. The characteristic frequency electrochemical impedance modulus of discarded blade specimen was reduced by less than 1 magnitude compared to that of original specimen. Conclusion After 8 cycles, electrochemical impedance modulus diagram of the organic coatings on discarded blade specimen was still a little higher than that of repaired blade specimen.
