C3N4涂层高速钢和C3N4涂层硬质合金刀具对调质钢、淬硬钢等进行切削试验,证明高速钢刀具经C3N4涂层后,使用寿命显著提高;硬质合金刀具经C3N4涂层后,使用寿命提高幅度不如TiC、PCBN涂层刀具;C3N4涂层刀具不适合切削颗粒增强复合材料
C3N4 coated high-speed steel and C3N4 coated cemented carbide cutting tools to quenched and tempered steel, hardened steel and other cutting tests show that high-speed steel tools after C3N4 coating significantly increases the service life; carbide tool after C3N4 coating, Life expectancy increase than TiC, PCBN coated tool; C3N4 coated tool is not suitable for cutting particle reinforced composite materials
