摘要: 基于负温度系数热敏陶瓷的阻温特性和结构陶瓷的高耐磨性,设计制造一种异种陶瓷复合的新型温度感知智能刀具。该智能刀具主体和温度感知模块分别由α/β-SiAlON结构陶瓷和LaCrO3-Al2O3热敏陶瓷组成,并分别通过放电等离子和微波烧结成形。通过高速切削镍基高温合金GH4169测试了该智能刀具的切削性能和温度感知功能。结果表明:该智能刀具具有优异的切削性能,在vc=200 m/min,f = 0.1 mm/r,ap = 1.0 mm时材料去除量最大,是商业陶瓷刀具WG300的1.4倍;该智能刀具具备良好的温度感知功能,最大感知温度超过700℃,温度感知灵敏度高,响应迅速。

Abstract: A new type of temperature sensing smart tool is designed and manufactured taking advantage of resistance-temperature characteristics of negative temperature coefficient thermal sensitive ceramics and excellent wear resistance of structural ceramics. The smart tool body and temperature sensing module are composed of α/β-SiAlON structural ceramic and LaCrO3-Al2O3 thermal sensitive ceramic, and prepared by spark plasma sintering and microwave sintering, respectively. The cutting performance and temperature sensing function of the smart tool are tested by high-speed machining nickel-base superalloy GH4169. The smart tool shows excellent cutting performance, and when vc=200 m/min, f=0.1 mm/r, ap=1.0 mm, the material removal amount is 1.4 times higher than that of the commercial ceramic tool WG300, meanwhile, as well as, the smart tool possesses good temperature sensing function. The maximum sensing temperature is above 700 ℃, temperature sensing sensitivity is high, and the response time is nanosecond.
