摘　　要：选取框架结构使用的螺纹钢作为试样,采用传统高温锰系磷化工艺和改进的中温锌系磷化工艺分别进行锰系磷化处理、锌系磷化处理,并比较了不同工艺磷化处理后螺纹钢的形貌、成分和耐蚀性。结果表明:锰系磷化处理和锌系磷化处理后螺纹钢的外观不同,但锰系磷化膜和锌系磷化膜都较致密。锰系磷化膜的成分Mn、P、O、Fe和C元素,锌系磷化膜的成分为Zn、P、O和C元素。锰系磷化处理和锌系磷化处理都能明显提高螺纹钢的耐蚀性,锰系磷化膜和锌系磷化膜都具有较好的防护作用。改进的中温锌系磷化工艺与传统高温锰系磷化工艺的防腐蚀效果相差不大,表明改进的中温锌系磷化工艺替代传统高温锰系磷化工艺具有可行性,可以用于框架结构用螺纹钢表面处理,在满足节能减排要求的同时,有效提高螺纹钢的耐蚀性。The screw-thread steel used in frame structure was selected as the sample,and it was treated by the traditional high-temperature manganese phosphating process and the improved medium-tempera‐ture zinc phosphating process respectively.The morphology,components and corrosion resistance of screw-thread steel treated by different phosphating process were investigated.The results showed that manganese phosphating film was composed of Mn,P,O,Fe and C elements,while zinc phosphating film was composed of Zn,P,O and C elements.Both manganese phosphating treatment and zinc phosphating treatment can obviously improve the corrosion resistance of rebar,manganese series phosphating film and zinc series phosphating film had a better protective effect on screw-thread steel,and both manganese phosphating film and zinc phosphating film had good protective effect.The anti corrosion effect of the improved medium-temperature zinc phosphating process was equivalent to that of the traditional high-temperature manganese phosphating process,which indicated that the improved medium-temperature zinc phosphating process was feasible to replace the traditional high-temperature manganese phosphating process.The improved medium-temperature zinc phosphating process can be used for surface treatment of the screw-thread steel used in frame structure to improve its corrosion resistance while meeting the requirements of energy saving and emission reduction.
