| Research Abstract |
To improve mechanical property and oxidation resistance of machined TiAl based alloys, Al diffusion treatment using Two-step process of an aluminum coating and a diffusion treatment was performed. The formation process of intermetallic layer during the diffusion treatment was investigated, and an optimum condition to resolve the machined defects was evaluated. In addition, the coating stability in high temperature oxidation was invesitigated.
