Abstract

Plasma-spray forming has been used to fabricate thick-wall tubes of MoSi2 and MoSi2 containing concentric layers of Al2O3 This process is being investigated as a potential fabrication method for producing tubular components of MoSi2 and MoSi2 composites for use in high temperature fuel-burner applications. Results will be reported on the spray forming method used to produce tubes of various sizes. The room temperature strength of pure MoSi2 tubes in the as-deposited condition,and after heat-treating at 1500 °C for 2 hours in vacuum, will also be reported. The strength of plasma sprayed MoSi2 tubes were measured via diametral compression of O-ring and C-ring sections in air at room temperature. Qualification of the strength distribution was based on Weibull statistical theory.
