Development and oxidation resistance of air plasma sprayed Mo–Si–Al coating on an Nbss/Nb5Si3 in situ composite

Mo?Si?Al coating, which is mainly composed of Mo(Si,Al)2 and Mo5(Si,Al)3, was developed to protect a Nbss/Nb5Si3 in situ composite by air plasma spraying. After oxidation at 1250?C, the oxidation curve followed parabolic law and even after oxidation for 100h, the weight gain of Mo?Si?
