Research Hotspot and Trend of Polycrystalline Cubic Boron Nitride Tools:Knowledge Map Analysis Based on CNKI and WOS Database
Polycrystalline cubic boron nitride(PCBN)tools is a superhard material tool based on cubic boron nitride powder and binder sintered.Because of its advantages of high hardness,high thermal stability and good wear resistance,it has received extensive at-tention in the field of high-speed,high-efficiency and high-precision metal processing.Based on the relevant papers in CNKI and WOS databases from 1993 to 2023,CiteSpace software was used to create a PCBN tool knowledge map,and its research hotspots and develop-ment trends were analyzed.The results indicate that:through the national cooperation map and institutional cooperation map,the phe-nomenon of close integration of industry,university and research institutions can be shown;through the collinear map of domestic and foreign keywords and clustering comparison,the development hotspots are tool materials,preparation technology,cutting process and wear mechanism;the research context shows that the future trend will in the direction of material diversification,combination of simula-tion and experiment,microscopic research,and tool specialization.
