摘　　要：研究了一种可应用于汽车活塞环的新型常温锌镍锰系磷化液。考察了溶液组分及工艺参数对磷化膜耐蚀性能的影响,采用硫酸铜点滴试验方法对磷化膜耐蚀性能进行了测试和评价,确定了最佳磷化工艺。研究表明,该磷化液可降低生产成本,而且环保,具有良好的工业应用前景。A new Zn-Ni-Mn phosphating solution at room temperature was investigated to the application for piston rings. The corrosion resistance of phosphate coating was determined and evaluated by copper sulfate dropping test. The influence of solution components and process parameters on the corrosion resistance of coating was examined, and the optimum preparation conditions were obtained. The results show that this new phosphating solution not only could reduce the production costs, hut also has the environ- mental non-toxic chanracteristics and a good prospect for industrial applications.
