通过硬质颗粒弥散，提高了Ｓｉ３Ｎ４基和Ｔｉ（ＣＮ）基陶瓷的硬度和切削能力，解决了一系列超硬难加工材料的加工问题。新型陶瓷刀具在工业泵、轧辊、矿山机械、轴承和汽车等领域中得到了应用，提高了生产效率，降低了加工成本，促进了机械加工工艺的改革，并带来很大的社会经济效益。 Through the dispersion of hard particles, the hardness and cutting ability of Si3N4-based and Ti (CN) -based ceramics are improved, and the processing problems of a series of super-hard and difficult-to-process materials are solved. The new type of ceramic tool has been applied in the field of industrial pumps, rollers, mining machinery, bearings and automobiles, which has raised the production efficiency, reduced the processing cost, promoted the reform of mechanical processing technology and brought great social and economic benefits.
