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?

Microstructure and oxidation of multi-layer MoSi2–CrSi2–Si coatings for SiC coated carbon/carbon composites

Multi-layer MoSi2?CrSi2?Si anti-oxidation coatings with different compositional ratios were prepared on the surface of SiC coated carbon/carbon (C/C) composites by a two-step pack cementation method. The microstructure and anti-oxidation performance of the coating were studied.

Oxidation of Ti2AlC bulk and spray deposited coatings

? Oxidation of bulk Ti2AlC and spray deposited Ti2AlC coatings in the temperature range 700?1200?C has been studied. ? It has been shown that bulk Ti2AlC forms a protective layer of ?-Al2O3 already at 700?C but this good oxidation properties for bulk are not easy to transfer to the coatings. ?
