Tóm tắt

Induction plasma spraying was used to produce freestanding parts of Mo5Si3‐boron (Mo5Si3‐B) composite materials. Four different Mo5Si3‐B compositions were prepared and oxidized isothermally at 1210°C in air at atmospheric pressure. The high‐temperature oxidation performance of these materials was dependent strongly on the boron content in the specimens. The composite that contained 2.0 wt% boron exhibited excellent resistance to oxidation, as indicated by the almost‐zero change in specimen mass after oxidation for 24 h.
