Silicon Nitride for Automotive Applications

Kyocera silicon nitride SN220M has been developed for automotive applications. Its charactaristics have been well established and examined. This paper presents the static fatigue behavior, along with physical properties and a review of automotive applications of the SN220M. Also, high performance silicon nitride materials, SN251 for gas turbine and SN235 for automotive applications, are discussed for further increase of engine performance.
