Ceramic cutting tool and manufacturing method thereof

The present disclosure provides a ceramic cutting tool and a method of manufacturing the same, the ceramic cutting tool including cermet particles and a cushioning material, the cushioning material having a hardness less than that of the cermet particles, at least a portion of the cushioning material being dispersed between the cermet particles to connect the cermet particles to each other. According to the ceramic cutter disclosed by the invention, the buffer material can be dispersed among the metal ceramic particles to connect the metal ceramic particles, so that the toughness of the ceramic cutter can be improved to reduce the brittleness of the ceramic cutter, and the ceramic cutter is prevented from cracking when falling onto the ground or cutting hard objects. 本公开提供一种陶瓷刀具及其制造方法，所述陶瓷刀具包括金属陶瓷颗粒和缓冲材料，所述缓冲材料的硬度小于所述金属陶瓷颗粒的硬度，所述缓冲材料的至少一部分分散在所述金属陶瓷颗粒之间将所述金属陶瓷颗粒彼此连接。根据本公开的陶瓷刀具，缓冲材料可分散在金属陶瓷颗粒之间将金属陶瓷颗粒彼此连接，可提高陶瓷刀具的韧性以降低其脆性，从而防止陶瓷刀具在落地或切硬物时发生崩裂。
