1. High hardness, titanium carbonitride-based cermet hardness is higher than WC-based cemented carbide, generally suitable for machining cast iron, malleable cast iron, ductile iron, carbon steel, alloy steel, titanium alloy and other metal materials.
2. It has good wear resistance, and the wear rate is extremely low when cutting steel at high speed.
3. High heat resistance, the tool can still be cut at high temperature of 1100-1300 ℃, and the cutting speed can be 2-3 times higher than that of WC-based cemented carbide, up to 200-400m/min.
4. High oxidation resistance, TiO2 formed after the oxidation of TiC has a lubricating effect, so the oxidation degree of Ti(C,N)-based cermet is about 10% lower than that of WC-based cemented carbide.
5. Good chemical stability, when the Ti(C,N)-based cermet tool made by it is cutting, Mo2O3, nickel molybdate and TiO2 film will be formed on the contact surface between the tool and the chip work. At 700- At 900 °C, it is often difficult to bond, and it is not easy to form built-up edge, which is beneficial to improve the surface quality of the workpiece and form a mirror surface. This feature makes it very suitable for dry cutting, which is conducive to saving production costs.
