Research Abstract |
γ-TiAl is hopeful as structural material of advanced gas turbines and jet engines, because of its low density and mechanical properties at high temperature. However, oxidation resistance is relatively poor and so the material temperature should be below 750℃. In this study, oxidation-resistant coating was developed for this material to solve this problem. Oxidation resistance of high-strength Ti-Al-Ag was evaluated and the coating compositions were investigated using EQ coating theory.
