Comparative investigation of structure, mechanical properties, and oxidation resistance of Mo-Si-B and Mo-Al-Si-B coatings

[Display omitted] •Hard Mo-Si-B and Mo-Al-Si-B coatings with h-MoSi2 phase as a main component.•Mo-Si-B possess higher hardness, improved oxidation resistance and better thermal stability.•Coatings withstand short-term oxidation at 1600 (Mo-Al-Si-B) and 1700°C (Mo-Si-B).•Oxidation is accompanied by...
