Stannate conversion coating

Stannate conversion solution typically consists of K4Sn04, NaOH, C2tt3Na02 and Na4P207 with alkaline pH such as pH=l 1.6 and processing temperature at around 80°C [20,21]. Stannate coatings on Mg and its alloys are formed by initial dissolution of substrate Mg followed by deposition of coatings after concentrations of Mg and stannate ions reach critical concentrations... [Pg.547]
