Silicon nitride ceramic cutter, and preparation method and application thereof
The invention belongs to the technical field of ceramic materials, and particularly relates to a silicon nitride ceramic cutter, and a preparation method and application thereof. The silicon nitride ceramic cutter with a high-precision arc blade, a chip breaker groove, surface patterns and other complex shapes can be prepared, the cutting resistance is reduced, and the cutting efficiency is improved; the silicon nitride powder is doped with a sintering aid, so that the fracture toughness and the strength of silicon nitride ceramic can be effectively improved; and according to the silicon nitride ceramic cutter, and the preparation method and application thereof, the technical problems that in the prior art, a silicon nitride ceramic cutter with a high-precision chip breaker groove used for improving the cutting efficiency and a surface pattern structure cannot be prepared, and the silicon nitride ceramic cutter is high in preparation cost and short in service life can be effectively solved.
本申请属于陶瓷材料的技术领域，尤其涉及一种氮化硅陶瓷刀具及其制备方法和应用，本申请提供的氮化硅陶瓷刀具的制备方法，通过光固化含氮化硅粉体的陶瓷浆料，可制备带有高精度的圆弧刀刃、断屑槽、表面花纹等复杂形状的氮化硅陶瓷刀具，减小了切削阻力，提高了切削效率；通过在氮化硅粉体中掺杂烧结助剂，能有效提高氮化硅陶瓷的断裂韧性和强度，本申请提供的氮化硅陶瓷刀具及其制备方法和应用，能有效解决现有技术中无法制备带有用于提高切削效率的高精度的断屑槽、表面花纹结构的氮化硅陶瓷刀具以及氮化硅陶瓷刀具制备成本高、使用寿命短的技术问题。
