MANUFACTURING METHOD FOR BIONIC CERAMIC CUTTER AND MANUFACTURED BIONIC CERAMIC CUTTER

摘要

Disclosed in the present invention are a manufacturing method for a bionic ceramic cutter and a manufactured bionic ceramic cutter. The bionic ceramic cutter is formed by alternately laying a hard layer material and a soft layer material. During loading, each time one layer of the hard layer material or the soft layer material is laid, a pressing head die is used for pre-pressing once, different layers are pre-pressed by means of different or the same pressing head grinding tools, and the last layer is pre-pressed by means of a pressing head die with a linear cross section, so that the interfaces of a transition zone between heterogeneous layers have different textures and are interlocked, thereby improving the crack propagation path, improving the interface bonding strength, improving the fracture toughness, and significantly prolonging the service life.
