Oxidation resistant coatings for ultrahigh temperature refractory mo-base alloys

Abstract

The use of Mo base alloys is limited by severe oxidation above about 650 °C. While MoSi2 coatings offer protection at high temperature, they are ineffective at low temperature. An integrated coating design has been developed based upon (B + Si) co-deposition and an in-situ diffusion barrier that offers robust, long term oxidation protection and self-healing for Mo alloys over a wide temperature range to over 1600 °C.
