Development of Self-Toughening Silicon Nitride Matrix Nanocomposite Ceramic Tools and Cutting Performance

Abstract:

A series of self-toughening silicon nitride matrix nanocomposite ceramic tool materials are fabricated by hot-press technology at different sintering processes. And their microstructure has been observed and analyzed by a scanning electron microscope (SEM). Finally, the tests of mechanical properties and the cutting performance of the new ceramics are presented. The research results showed that the nanocomposite ceramic tool materials GGW20T5 and GGW20TC25 have better mechanical properties and possess a stronger wear resistance in cutting 40Cr alloy steel.
