The goal of this research is to determine the mechanisms of hot corrosion in metals. Electrochemical measurements will be employed to provide needed data on the corrosion reactions taking place. The role of chromium in retarding sulfidation will be analyzed in fused sodium sulfate at 1200 degrees Kelvin. Effects of vanadate solutes, which accelerate hot corrosion will be determined. Shifts in melt chemistry which affect sulfidation kinetics will be determined. Improved theoretical understanding of the mechanisms of hot corrosion should result from the research.

这项研究的目的是确定金属热腐蚀的机理。将使用电化学测量来提供所需的发生腐蚀反应的数据。在1200开尔文的熔融硫酸钠中，将分析铬在延缓硫化方面的作用。将确定加速热腐蚀的钒酸盐溶质的影响。将确定影响硫化动力学的熔体化学变化。这项研究应该会从理论上提高对热腐蚀机理的理解。
