摘　　要：以C72D2钢丝为研究对象,研究了合金化热镀锌钢丝镀层结构,探讨合金化镀层对7×7-Φ2.3 mm钢丝绳耐腐蚀性能的影响。合金化镀层的相结构为从基体向外,由铁质量分数7.0%~11.5%的δ相到5.5%~6.2%的ζ相,铁质量分数由高到低变化,镀层主要成分为FeZn_(13)。钢丝绳热镀锌合金化处理后的耐腐蚀性能远远超过热镀锌的。Taking C72D2 steel as research object,the coating structure of alloying hot-dip galvanized steel wire was studied,and alloying coating influence on corrosion resistance of 7×7 diameter 2.3 mm wire rope was discussed.The phase structure of alloyed coating is from the matrix outward,and from 7.0%~11.5% iron mass fraction δ phase to 5.5%~6.2% ζ phase,iron mass fraction changes from high to low,and the main coating composition is FeZn_(13).Wire rope corrosion resistance after hot-dip galvanizing and alloying treatment is far superior to that of hot-dip galvanizing.
