摘　　要：热镀锌因其优秀的抗腐蚀性能、广泛的环境适应性和良好的经济性被广泛用于交通工程钢构件的防腐蚀处理,但该技术存在高能耗、高污染、镀件尺寸受限、工人劳动环境差等缺点。本研究采用理论分析、试验室测试及工程现场评测相结合的方法,对新型纳米锌合金防腐涂层材料的防腐性能进行评估、测试,并在外观质量、与金属基体附着性、耐盐雾性能方面与传统热镀锌涂层进行比较,结果表明:新型纳米锌合金涂层外观质量良好、成膜致密、涂层厚度均匀,具有优秀的抗腐蚀能力,在国家“双碳”政策背景下,有望成为替代热镀锌涂层最具潜力的新型防腐处理技术。Hot dip galvanizing is widely used for anticorrosion treatment of steel components in transportation engineering due to its excellent corrosion resistance,wide environmental adaptability,and good economy.However,this technology has disadvantages such as high energy consumption,high pollution,limited plating size,and poor working environment for workers.This study adopts a combination of theoretical analysis,laboratory testing,and on-site engineering evaluation to evaluate and test the anti-corrosion performance of a new type of nano zinc alloy anti-corrosion coating material.It is compared with traditional hot-dip galvanized coatings in terms of appearance quality,adhesion to metal substrate,and salt spray resistance.The results show that the new nano zinc alloy coating has good appearance quality,dense film formation,uniform coating thickness,and excellent corrosion resistance.In the context of the national"dual carbon"policy,it is expected to become the most promising new anti-corrosion treatment technology to replace hot-dip galvanized coatings.
