本发明公开了一种汽车用高强钢表面锆化膜快速成膜的方法，其中的锆基转化液为水溶液，包含1～7g/L的锆化剂、2～8g/L的氧化剂、0.2～10g/L的络合剂和0.2～1.5g/L的促进剂，将预处理后的基体浸泡在调节PH值后的锆基转化液中进行锆化处理。本发明采用低成本的添加剂配制锆基转化液，可处理表面条件较差的高强钢基板，在表面形成耐蚀性，附着力性能优良的锆基转化膜，同时引入新型添加剂改善锆基转化液的成膜性能，做到加速锆化成膜的效果。

The present invention discloses a method for rapid formation of zirconium film on the surface of high-strength steel for automobiles. The Zr based conversion solution is an aqueous solution, which includes 1-7g/L of zirconium agent, 2-8g/L of oxidant, 0.2-10g/L of complexing agent, and 0.2-1.5g/L of promoter. The pretreated matrix is immersed in the Zr based conversion solution after adjusting the pH value for zirconium treatment. The present invention uses low-cost additives to prepare Zr based conversion solution, which can treat high-strength steel substrates with poor surface conditions, which form a Zr based conversion film with excellent corrosion resistance and adhesion performance on the surface. At the same time, new additives are introduced to improve the film-forming performance of Zr based conversion solution, achieving the effect of accelerating Zr film-forming.
