Silicon Carbide Radial Turbine Investigation.
Abstract
The report describes the experimental and theoretical efforts to fabricate a small radial ceramic turbine wheel by the chemical vapor deposition (CVD) of silicon carbide (SiC). The CVD process and the fabrication of SiC wheels in tungsten mold is described. A lower cost process for producing graphite molds is also presented. Although certain aspects of the SiC wheel fabrication were shown to be feasible, a complete intact structure was not successfully made. Design aspects of the ceramic wheel including stress and thermal analysis are presented along with suggested mounting procedures. Recommendations for future work are also made. (Author)
