Nowadays, more and more consumers are choosing ceramic knives, so their performance is better than metal knives, especially zirconia ceramic knives, which is another ideal tool material in addition to boron nitride ceramic knives. , it has played a positive role in both life and work. With the development of science and technology, in addition to many difficult-to-machine materials, zirconia ceramic tools can play a role in the field of high-speed cutting by virtue of their excellent heat resistance, wear resistance and chemical stability, and present unparalleled performance of other tools. advantages.

　　For zirconia ceramics, the smaller the grain size, the higher the hardness and strength of the ceramic material. , when the grain size is as small as about 100nm, there will be a big breakthrough in strength and hardness. However, nanopowder is very active, has low interface reaction activation energy, and is easy to grow during the sintering process. Although inhibitors are added, the effect is still not ideal.  

      Facts have proved that zirconia ceramic tool material is a very excellent high-speed cutting tool material. It has better chemical stability than cemented carbide and can cut at high speeds and last for a long time. Not only can work efficiency be improved , cutting accuracy can also be improved.   

     Through research on the components, preparation processes and material design of zirconia ceramic tool materials, the toughness and impact resistance of tool materials can be improved while maintaining high hardness and high wear resistance, so that they can better meet the needs of cutting technology.
