Integrated ceramic cutter with PTC (Positive Temperature Coefficient) effect temperature measurement and cutting functions and preparation method thereof
The invention provides an integrated ceramic cutter with PTC effect temperature measurement and cutting functions and a preparation method thereof. The integrated ceramic cutter comprises a temperature measurement and ceramic matrix layer, the PTC temperature measurement layer is formed by sintering a temperature measurement material and an additive; the ceramic matrix layer is formed by sintering a matrix material, a binder and a reinforcing phase. The preparation method comprises the following steps: preparing each layer of material into powder, sequentially filling and paving each layer of material powder layer by layer, compacting, and finally carrying out hot pressed sintering. The invention further discloses application of the cutter. By selecting the temperature-sensitive material and designing the structure of the tool, the Vickers hardness, bending strength and fracture toughness of the obtained ceramic tool meet the requirements for the performance of the tool in industrial production, and the cutting function of the ceramic tool and real-time measurement of the cutting temperature in the cutting process are achieved.
本发明提供了一种具有PTC效应测温和切削功能一体化陶瓷刀具及制备方法，包括测温和陶瓷基体层；所述PTC测温层由测温材料，添加剂烧结形成；所述陶瓷基体层由基体材料，粘结剂，增强相烧结形成。制备方法为将各层材料制成粉体，按顺序将各层材料粉体逐层填铺并压实，最后进行热压烧结。本发明还进一步公开了所述刀具的应用。本发明通过选择温度敏感材料及对刀具结构的设计，使得本发明获得陶瓷刀具的维氏硬度、抗弯强度以及断裂韧度都满足工业生产中对刀具性能的要求，实现陶瓷刀具的切削功能及切削过程中对切削温度的实时测量。
