摘要

The high temperature oxidation behavior of TiAl alloys coated with Ti-Al-Cr alloys using magnetron sputtering method was studied. The results showed that Ti-Al-Cr coatings improved the oxidation resistance of TiAl alloys. The weight gains at 950°C for Ti-Al-Cr coatings are more than those at 1000°C. Oxide formed on the surface of Ti-50Al-15Cr coating after oxidation consisted of A1₂O₃, whereas oxide formed on the surface of Ti-50Al-10Cr coating after oxidation is composed of a mixture of a large portion of A1₂O₃ and a small portion of TiO₂. The effect of Ti-Al-Cr coatings on the improvement of oxidation resistance of TiAl alloys results from thermodynamic and kinetics factors contributing to Cr effect.
