Induction plasma spraying was used to produce freestanding parts of Mo 5 Si 3 ‐boron (Mo 5 Si 3 ‐B) composite materials. Four different Mo 5 Si 3 ‐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.
