目前在美国、西欧和日本90%的可转位刀片都是用含TiC、TaC和NbC的WC—Co无涂层硬质合金和TiC、Ti(C,N)、TiN、Al_2O_3涂层硬质合金制造的。应用最广的陶瓷刀具是添加ZrO_2、TiC、TiB_2、Ti(C,N)、Zr(C,N)、SiC的Al_2O_3基陶瓷刀片和添加Y_2O_3、TiC和TiN的Si_3N_4基陶瓷刀片。在日本,陶瓷刀片的使用量占8～10%,在美国占3～4％。 At present in the United States, 90% of the indexable inserts in Western Europe and Japan are made of WC-Co uncoated cemented carbide containing TiC, TaC and NbC and TiC, Ti (C, N), TiN and Al 2 O 3 hard coatings Made of alloy. The most widely used ceramic tools are Al_2O_3 based ceramic inserts with addition of ZrO_2, TiC, TiB_2, Ti (C, N), Zr (C, N) and SiC and Si_3N_4 based ceramic inserts with addition of Y_2O_3, TiC and TiN. In Japan, the use of ceramic blades accounted for 8 to 10%, in the United States accounted for 3 to 4%.
