摘　　要：采用静态质量损失法考察不同热浸镀锌温度对高锰钢在中性盐雾试验的防腐性能影响,利用扫描电镜观察高锰钢热浸镀锌层腐蚀前后镀锌层表面的微观形貌。试验结果表明,当热浸镀温度在540℃~560℃内,镀层厚度符合要求,且镀锌层腐蚀速率在该温度范围内随浸镀温度增加而减小,表明热镀锌法有助于增强高锰钢的防腐性能。The anti-corrosion performance effect of high Mn steel hot-dip galvanized coating during neutral salt spray test was researched by static weight-loss method.The microstructures of the coatings containinground corrosionwere analyzed by scanning electron microscope.The results show that the coating thickness will meet the requirement when the galvanized temperature is between 540~560℃.The corrosion rate decreases with the increase of immersion plating temperature,as proves that the method of hot-dip galvanized coating could enhance anti-corrosion performance of high Mn steel.
