Reaction Steps
A bath containing ammonium vanadate (23.4 g in 5 liters water; 0.04M) sodium fluoride (1.42 g/l 0.34M) was acidified with phosphoric acid (900 ml; 2.7M) until the pH of the bath containing the ammonium vanadate and sodium fluoride reached 1.5. A strip of aluminium (53%)/zinc (45%) coated steel was then dipped into the bath for varying contact time at different passivation temperatures. The results of the resulting coating film are given in Tables 1 to 3.
