| 中文摘要: |
| 目的 了解不同涂层体系及金属材料在新疆伊犁特克斯流域的腐蚀行为，为特克斯河流域水利开发提供设计依据。方法 通过实地投放金属涂层制品、涂层体系及金属材料，并按周期取样观察对比。结果 获得了8种金属涂层、14种金属与封闭涂层、5种富锌涂料体系、10种复合涂层体系、2种碳钢材料和5种不同不锈钢和碳钢面积比偶合件0.5，2 a的试验结果。结论 喷锌层是该水库中最适合的金属涂层；环氧封闭是表现最好的封闭涂层；环氧富锌是最好的富锌底漆；氯化橡胶、环氧沥青、环氧面漆、无溶剂耐磨环氧表面良好，适合用作面漆；脂肪族聚氨酯面漆、氟碳面漆不适合用于水下；可复涂聚氨酯用作面漆应视涂层体系谨慎使用；碳钢腐蚀速率和不锈钢与碳钢偶合件面积比之间存在显性的线性关系，不锈钢比例越大，碳钢腐蚀速度越快；镀锌层对钢丝绳有明显的保护作用，比未镀锌钢丝绳腐蚀较轻。 |

| Object To understand the corrosion characteristics of coating systems and metals in the Xinjiang Yili Tekes River to help design for water conservancy development of the Tekes River. Methods Samples of metal coating product, coating system and metal material were put at site to sample, observe and compare in different periods. Results Test results on eight metal coatings, fourteen metal coatings with sealing, five zinc rich coatings, ten composite coatings, two carbon steel and five couples of stainless steel and carbon steel in half year and two years were obtained. Conclusion Zinc coating is the best metal coating; epoxy sealer is the best sealer for metal coating; zinc rich epoxy is the best zinc rich coating; chlorinated rubber, epoxy asphalt, epoxy finish paint, solvent-free wear-resisting epoxy are suitable for using as top coatings; aliphatic polyurethane paint, fluorocarbon paint are not fit for using in water; recoatable polyurethane coating shall be used prudently according to the base coating; corrosion rate of carbon steel increases with the increase of stainless steel area, and typical linear relationship exists between corrosion rate of carbon and ratio of carbon area and stainless steel area; the larger the proportion of stainless steel, the faster the corrosion rate of carbon steel; the galvanized layer obviously protects wire rope. The corrosion of galvanized steel wire rope is less severe than that of ungalvanized steel wire rope. |
