摘要

SiC颗粒具有较高的硬度，使Al/SiCp复合材料在切削时刀具磨损剧烈。纳米硬质合金具有较高的硬度、韧性及良好的抗磨损能力。制备了纳米硬质合金刀具WC-7Co，对Al/SiCp复合材料进行了切削实验，研究了纳米硬质合金刀具磨损机理和Al/SiCp复合材料的切屑去除机理，以及刀尖处后刀面磨损值。研究认为，纳米硬质合金刀具磨损的机理为SiC颗粒的微切削作用引起的磨料磨损，及SiC颗粒对刀尖刃口的高频、断续冲击引起的微崩刃及微破损，Al/SiCp复合材料的切削实质是断续切削；Al/SiCp复合材料去除机理为切屑的崩碎去除；纳米硬质合金后刀面磨损值较普通硬质合金小30%~50%。

Abstract

The SiC particle has higher hardness in the Al/SiCp composite

and the tool wear is fast when Al/SiCp composite is machined. Nano-cemented carbide is a novel material

which is superior to common cemented carbide on physical and mechanical properties

such as high hardness

toughness

flexural strength and higher wear resisting property. In this paper the nano cemented carbide tool WC-7Co was prepared

and the cutting experiment was done. And wear mechanism of nano cemented carbide tool and chip removal mechanism were studied. Results shaw

the wear mechanism of nano cemented carbide tool is abrasion wear due to the micro-cutting of SiC particles

and micro-chipping and micro-breakage of cutting edge under the high frequent interrupted impact of the SiC particles. The essence of cutting Al/SiCp is interrupted cutting. The Al/SiCp chip removal mechanism is breakout of the chip. Flank wear value of nano cemented carbide tool is about 30-50% less than common cemented carbide.
