为揭示有机物、钒盐作为添加剂研究了两种添加剂对Ti-Zr转化膜膜层生长与耐蚀性能的影响.通过涡流测厚仪、扫描电子显微镜、X射线能谱仪、点滴腐蚀法、Tafel极化曲线和交流阻抗等研究了转化膜的厚度、微观形貌、化学成分及耐蚀性能等.结果表明：同时添加钒盐和有机物，在30s内即可获得有色的钛锆转化膜；同时添加钒盐和有机物时形成的膜层致密、均匀，表面平整，膜层中氧化物含量明显增加；相较于无添加剂的Ti-Zr转化膜，膜厚增加了4倍以上，耐点滴腐蚀时间延长了3倍多，腐蚀电流密度降低至原来的1/6、极化电阻提高了3倍以上，耐蚀性能得到显著提高.

In this paper,two additives including vanadate and organic were added in the mixed Ti-Zr solution ,and the effects of these additives on the behaviors of Ti-Zr conversion coating were investigated.Then,the micrographic structure and thickness of the coating were analyzed by using an optical microscope and eddy current thickness meter,respectively,and the corrosion resistance of the coating was discussed by dropping corrosion test,Tafel polarization curves and electrochemical spectroscopy(EIS).The results indicate that,with the coordination effect of vanadate and organic,Ti-Zr conversion coating can be prepared at room temperature with a time consumption of only 30s,the thickness,anti-corrosion time,corrosion current density and impedance of the coating are respectively 4,3,1/6,and 3 times that of the coating without any additives.It is thus concluded that the optical corrosion resistance of conversion coating was prepared by added the two additives simultaneously into Ti-Zr solution.
