Grain-oriented SiAlON ceramic cutting blade and preparation method thereof
The invention relates to the field of cutting tools, and discloses a grain-oriented SiAlON ceramic cutting blade and a preparation method thereof.The blade comprises a SiAlON ceramic layer and at least one base body; crystal grains in the SiALON ceramic layer are arranged at the cutting edge of the blade along a preferable orientation; the substrate and the SiALON ceramic layer are compounded through an interface with an interlocking penetrating structure, and the interface structure comprises a composite layer formed by at least one heterogeneous material; the grain orientation of each cutting edge of the blade is consistent, and the relative angle of the grain orientation of each tool nose is kept consistent. The novel SiAlON ceramic blade has a novel overall structure and a microstructure, and the novel SiAlON ceramic blade with the macro-microstructure collaborative design can solve the problems that an existing ceramic blade is poor in durability, poor in groove abrasion resistance, low in overall strength and the like.
本申请涉及切削工具领域，公开了一种晶粒定向SiAlON陶瓷切削刀片及其制备方法，该刀片包括一个SiAlON陶瓷层和至少一个基体；所述SiALON陶瓷层中的晶粒在刀片刃口处沿优选的取向排列；所述基体与SiALON陶瓷层之间通过一个具有互锁穿插结构的界面复合，其中该界面结构包括由至少一种异质材料构成的复合层；所述刀片的每个切削刃在晶粒取向上具有一致性，每个刀尖的晶粒取向相对角度保持一致。本发明刀片具有新型整体和微观结构，宏微观结构协同设计的新型SiAlON陶瓷刀片可解决现有陶瓷刀片耐用性差，抗沟槽磨损性能差、整体强度低等问题。
