Study of grinding process and strength for ceramic heat

Jun 01, 1991 Steps are described for the successful development of a ceramic thermally insulated turbine engine. The strength of the ceramic engine parts can be effectively increased depending on the grinding methods used. Because many microcracks have been observed after the grinding of engine parts with low strength, grinding processes are, therefore, studied.
