Abstract

Ultrafine WC-Co cemented carbide cutting inserts were prepared by direct low pressure sintering and low pressure sintering after the powder pretreatment, tool life tests of continuous cutting superalloy GH2132 were carried out, respectively. ZEISS continuous zoom stereo microscope and microphotograph system were used to observe flank surface wear morphology of the cutting inserts, and analysis the topography and elements of central wear region of flank surface by X-ray energy dispersive spectrometry and scanning electron microscope. The results show that the main wear mechanism of ultrafine cemented carbide cutting inserts is adhesive wear, and the wear resistance of ultrafine cemented carbide cutting inserts that low pressure sintering after powder pretreatment is superior to direct sintering, powder pretreatment helps increase the resistance of abrasive wear, adhesive wear and oxidative wear as well as diffusive wear of cutting inserts.
