现代陶瓷刀具可分为三大类,即:①氧化物陶瓷包括氧化铝陶瓷和氧化铝/氧化锆陶瓷;②混合陶瓷包括氧化铝/碳化钛陶瓷、氧化铝/氮化钛陶瓷与氧化铝/碳化钛/碳化钨陶瓷;③非氧化物陶瓷包括立方氮化硼(CBN)陶瓷和氮化硅(Si_3N_4)陶瓷。要说到它们的使用性能,最佳的当然是立方氮化硼陶瓷,但其成本限制了它的广泛应用。在其它的陶瓷材料中,热压混合陶瓷的硬度最高,它可用来切削淬火钢与激冷铸铁。氮
Modern ceramic tools can be divided into three categories, namely: ① oxide ceramics including alumina ceramics and alumina / zirconia ceramics; ② hybrid ceramics including alumina / titanium carbide ceramics, alumina / titanium nitride ceramics and alumina / Titanium carbide / tungsten carbide ceramics; ③ non-oxide ceramics including cubic boron nitride (CBN) ceramics and silicon nitride (Si_3N_4) ceramics. Talking about their performance, the best of course is cubic boron nitride ceramics, but its cost limits its wide range of applications. Among other ceramic materials, hot-pressed hybrid ceramics have the highest hardness, which can be used to cut hardened steel and chilled cast iron. nitrogen
