中文摘要:
      目的 研究沿海地区输电铁塔防护涂层体系的腐蚀失效行为, 评估涂层的防护性能, 为铁塔防护涂层寿命体系评定和修复提供试验依据。方法 分别采用热镀锌、 热镀锌/冷涂锌复合涂层、热镀锌/带锈环氧涂层三种技术方案, 对铁塔角钢材料进行防腐保护, 采用中性盐雾方法模拟沿海环境对试样进行耐蚀性测试, 通过试样表面形貌观察、 极化曲线、 以及阻抗谱等电化学手段对保护效果进行评价。结果 热镀锌、 热镀锌/冷涂锌复合涂层在盐雾150 h出现大面积腐蚀, 热镀锌/带锈环氧涂层在盐雾2000 h未发生明显腐蚀。结论 热镀锌/带锈环氧涂层的耐蚀性能优于热镀锌/冷涂锌漆和热镀锌涂层。
英文摘要:
      Objective To study the corrosion failure behavior and evaluate the protection property of the coating for the corrosion critical component on transmission line iron tower, and to provide test proofs for determining the calendar life of coatings and formulating maintenance compendium. Methods The anti-corrosion properties of Zn coating, zinc rich paint/Zn, and rust coating/Zn for the transmission line iron tower were investigated by neutral salt spray test to simulate the environment of coastal area. The morphology and electrochemical properties of the coatings were evaluated by microscope, polarization curve and EIS. Results The corrosion occurred in large area of the Zn coating and zinc rich paint/Zn coating after 150 h of salt spray treatment, while no obvious corrosion was observed with rust coating/Zn after 2000 h of salt spray treatment. Conclusion The anti-corrosion performance of rust coating/Zn was superior to the other two coatings.
