This paper describes fabrication of silicon nitride radial turbine wheels 90 mm in diameter. The wheels were hot spin tested without failure at turbine tip speeds up to 600 m/s.The reliability of shrink fit of metal shaft and ceramic wheel was demonstrated in a turbocharger test.Results of the hot spin test are discussed in relation to the nature of defects and compared with the analytic prediction using Weibull statistics and finite element analysis.
