摘要
研制了一种新型低温锌系磷化液。通过耐蚀性、电化学测试及扫描电镜观察,表明碳钢经磷化后改善了阳极溶解性能,具有良好的耐蚀性能。磷化膜结晶组织呈网片状结构,均匀、密集,弥散分布,属结晶型磷化膜。该工艺成本低、成膜快、耐蚀性好、性能稳定,具有工业推广价值。
A new type phosphating solution of zinc series at low temperature was prepared. Electrochemical test and scanning electron microscope method were investigated to analyse the phosphating film. The results indicated that the anodic dissolution performance of the carbon steel was improved after phosphating. According to the surface analysis, the phosphating film was crystal type, which appeared net and slices structure. Since this film was compact and uniform, it possessed good corrosion resistance. The phosphating process has advantages such as low cost, fast film-forming rate, stable performance and wide application value in industry.
