采用硬质合金涂层刀具对镍基合金In718进行了车削试验,分析了硬质合金刀具的磨损形态、磨损机理,并给出了不同条件下的刀具寿命。结果表明,涂层硬质合金切削In718时的主要磨损形式为涂层剥落。
The coated carbide tool is used for turning of Inconel718. The modes and mechanism of tool wear of coated carbide insert has been analyzed. Tool life is given out in different conditions. The results show that mean mode of tool wear of coated carbide insert is the surfacc spall.
