利用UMT-2多功能摩擦磨损试验机对镍基合金Inconel 718与硬质合金刀具对偶时的摩擦磨损特性进行研究,揭示法向载荷和滑动速度对摩擦副摩擦因数的影响,通过SEM观察试样摩擦形貌并分析磨损机制.研究结果表明:摩擦副的摩擦因数随着法向载荷的增大而减小,随滑动速度的增大而增大;Inconel 718镍基合金与硬质合金对偶时的磨损机制主要为黏着磨损、磨粒磨损和氧化磨损.%The friction and wear properties of Inconel 718/carbide tool were studied on a UMT-2 type wear tester, revealed the effects of normal load and sliding velocity on friction coefficient, surface topographies of pin sample and wear mechanism were analysed by SEM. The results show that the friction coefficient is decreased with the increase of load and increased with the increase of sliding velocity. The wear mechanisms are mainly adhesive wear,abration wear and oxidation wear.
