| Abstract: | A new chromate-free passivation solution consisting of K2TiF6, HNO3, H3BO3, C6H11 O7Na, NaNO3 was used to treat the galvanized surface. Being poisonless, low-cost, and simple in handling, the solution can generate a bluish-white, corrosion -resistant passive film on the galvanized surface. The NSS time of the film reaches 43 hours. |
