In an effort to more accurately predict diffusion kinetics of oxygen into titanium during heat-treatment, the Wyman-Gordon Company commissioned this study to obtain an accurate rate of alpha case formation within titanium and to investigate the use of coatings to reduce alpha case formation. This project consisted of heat-treating Ti-6Al-4V and Ti-6Al-4V ELI samples that were uncoated, coated with an SJ, and SJ advanced coating over a period of time consistent with their heat-treatment cycle. These samples were analyzed through optical microscopy and microhardness to determine alpha case depth. The project concluded with a cost analysis, which aimed to find the most economic and optimal solution to reducing alpha case formation.
