Thermistor temperature measurement and cutting function integrated ceramic cutter and preparation method thereof
The invention provides a thermistor temperature measurement and cutting function integrated ceramic cutter and a preparation method thereof. The thermistor temperature measurement and cutting function integrated ceramic cutter comprises a thermosensitive layer and a ceramic matrix layer, the thermosensitive layer is formed by sintering a temperature measuring 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 spark plasma sintering (SPS). The invention further discloses application of the cutter. By selecting the temperature sensitive material and designing the cutter structure, the Vickers hardness, the bending strength and the fracture toughness of the obtained ceramic cutter all meet the requirements for the performance of the cutter in industrial production, and the cutting function of the ceramic cutter and real-time measurement of the cutting temperature in the cutting process are achieved.
本发明提供一种热敏电阻测温和切削功能一体化陶瓷刀具及制备方法，其包括热敏层和陶瓷基体层；热敏层由测温材料，添加剂烧结形成；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，最后进行放电等离子烧结(SPS)。本发明还进一步公开了刀具的应用。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座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。
