Environmental degredation of materials


Coalesence if silicon dioxide islands below a chromium oxide scale during high temperature oxidation of a fine grained stainless steel alloy.

Hot corrosion of SiC exposed to molten sodium sulfate at 1100C for 300 hours.

Although stainless steels rely on the formation of a protective chromium oxide scale, additional oxidation resistance can be achieved if silicon is added to the alloy to form a continuous silicon dioxide scale. Typically, the concentration of silicon required for this to occur is high enough to form brittle, low melting temperature phases that are detrimental to its mechanical properties. Our research involves investigation of processes by which a silica scale can be formed rapidly without degradation of alloy mechanical properties, leading to the development of highly corrosion resistant alloys with lower concentrations of chromium, which is both expensive and strategic.

Another area of interest is the study of diffusion mechanisms in thermally grown protective oxide scales by the 'tracer oxidation' process. Our research involves modeling the diffusion process such that the grain boundary and bulk diffusivities of cations and anions can be estimated from the tracer concentration profile in the oxide.
