The Oxidation kinetics of Ti-48Al-2Nb-2Cr composites (TANC) with addition of different weight contents of CaF2 solid lubricant was evaluated. It is indicated that oxidation dynamic curve follow quasi-parabolic rate law under 800 °C. Once the temperature exceed 1100 °C, the oxidation dynamic curve seems to do not follow quasi-parabolic rate law. The contents of solid lubricant in TANC matrix occur an important influence for oxidation resistance
