Abstract
Sliding friction and wear tests were carried out in a special tribometer assembled on a CA6140 turning lathe, and high-speed milling experiments were performed on a DMU-70V CNC machining centre, to investigate the friction and wear properties of two different cemented carbides (WC-10Co and WC-12Co) against aluminum alloy. The surface morphologies of the worn surfaces were observed by a S-570 scanning electron microscope. The diffusion behaviors of Co and Al elements were analyzed by a JXA-8800 electron microprobe. The results show that the friction coefficients of both cemented carbides decrease with the increase of normal load and sliding speed under the same friction condition. The friction coeffcient of WC-12Co is larger than that of WC-10Co, but the wear volume loss of WC-12Co is lower than that of WC-10Co. Under the same milling condition, the wear rate and work-piece surface roughness of WC-12Co tool are better than that of WC-10Co tool. The main wear mechanisms of ultra-fine grain cemented carbide are abrasive wear, adhesive wear and diffusion wear.
