| 摘 要： | 为充分对比不同类型金刚石涂层刀具的切削性能，定制几种不同类型金刚石涂层刀具进行等静压石墨切削加工，并与WC硬质合金刀具和TiAlN涂层刀具的切削情况对比，分析不同类型金刚石涂层刀具的涂层形貌、切削寿命、加工后的表面质量以及切削力。结果表明:制备的金刚石涂层刀具的涂层形貌主要为纳米晶和微晶，其寿命是硬质合金和TiAlN涂层刀具的10倍以上，且几种不同类型的金刚石涂层刀具寿命差异较小；金刚石涂层表面的晶粒细化可以降低加工表面的粗糙度和切削力，涂层脱落是金刚石刀具的主要磨损形式。

| Abstract: | To compare the cutting performance of different types of diamond coated tools, a variety of tools with different diamond coated materials were selected for the machining of graphite materials, and WC cemented carbide tool and TiAlN coated tools were used for comparison.The cutting life, coating morphology, surface quality and cutting force of different diamond coated tools were analyzed.The results show that the coating morphologies of diamond coated tools are mainly nanocrystalline and microcrystalline.The cutting life of diamond coated tools is more than ten times that of cemented carbide and TiAlN coated tools.The cutting life of several different types of diamond coated tools has little difference.However, the refinement of diamond coated surface grains can reduce surface roughness and the cutting force.Coating falling off is the main wear form of diamond tools. |
