| 目的 探究球磨前处理对钢件表面残留锈蚀度及其对热浸镀锌漏镀的影响，以期开发一种环境友好型的热浸镀锌工艺。方法 采用自主设计的高温双筒球磨机，对热浸镀锌钢件进行前处理。采用光学与电子显微镜分析球磨参数对钢件表面残留锈蚀度的影响。对球磨后的钢件进行热浸镀锌，采用扫描电镜(SEM)、X-射线衍射仪(XRD)以及高温悬滴式接触角测定仪研究钢件表面残留锈蚀产物及其对热浸镀锌漏镀的影响。结果 随着磨球粒径的增大，钢件表面残留锈蚀度a先减小后增加，磨球粒径为5 mm时达到最小值;随着滚筒转速和球磨时间的增加，钢件表面残留锈蚀度不断减少;当磨球粒径为5 mm、滚筒转速为140 r/min和球磨时间为40 min时，钢件表面残留锈蚀度a可减少到0。随着钢件表面残留锈蚀度的减小，锌液滴与基体间的接触角减小。当残留锈蚀度达到0时，接触角q =84°，锌液在基体表面均匀铺展，可避免漏镀的发生。结论 球磨除锈可以代替酸洗除锈，以减少热浸镀锌工艺对环境的污染。 |
| 英文摘要: |
| Batch hot-dip galvanizing is a mature corrosion protection method. However, the waste acid and gas generated in the pretreatment seriously pollute the environment, which urgently requires the development of an environmentally friendly hot-dip galvanizing. Ball-milling is a promising surface treatment method. The use of ball-milling instead of pickling in the traditional hot-dip galvanizing can avoid the generation of waste acid and meet the sustainable development requirements of green environmental protection. |
