Research Abstract |
This project has focused on designing an effective coating system against carbon based high temperature structural materials. Platinum group metals were chosen as candidates for a diffusion barrier that prevents carbon outward and oxygen inward diffusion. Their applicability was examined on the basis of carbon diffusion behavior. Pt is found to possess quite low carbon diffusivity, suggesting that Pt is promising for this type of application.
