Process temperatures, alloys/coatings

The objective of surface modification by CVD is to develop additional corrosion protection for high-temperature alloys (e.g., Fe-25Cr-0.3Y) beyond that achieved by reactive-element additions which will be effective for a long period. Because CVD is a high temperature process, the following topics must be discussed before we can develop successful high-temperature corrosion-proteetion coatings. ... [Pg.422]

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]
