This abstract first appeared for US patent application 18467936 titled 'FUNCTIONALLY GRADED SiAlON COMPOSITECUTTING TOOL
Original Abstract Submitted
A functionally graded (FG) SiAlON composite cutting tool includes a cutting head having a cutting surface containing the FG SiAlON composite. The FG SiAlON composite is obtained by sintering one or more powder compositions containing SiOparticles having a particle size of 20 to 50 nanometers (nm), AlN particles having a particle size of up to 100 nm, SiNparticles having a particle size of 300 to 500 nm, AlOparticles having a particle size of up to 100 nm, YbOparticles having a particle size of up to 100 nm, and one or more reinforcement additives selected from the group consisting of cobalt (Co) particles, titanium carbonitride (TiCN) particles, cobalt alloy particles, and a boron nitride compound. The one or more reinforcement additives have an average particle size in a range of 50 nm to 35 micrometers (μm).
