摘要
锌基合金材质零配件具有力学性能高、摩擦性能优良、耐磨性能好、无火花和无磁性等特点,可以代替价格较贵的(锡、铝)青铜和(铅)黄铜等铜合金以及巴氏合金等制造轴瓦、轴套、蜗轮、滑块和丝母等耐磨减摩零件。由于锌基合金具有原材料价格低廉、熔化耗能少、熔烧无污染,对成形方法适应性广和切削加工性好等一系列优点,因而,采用锌基合金制造耐磨和减摩零件有着巨大的经济效益和社会效益。我国锌资源丰富,储量占世界总储量的三分之一,居世界第一位,具有发展锌基合金得天独厚的优势。
Zinc base alloy friction material spare parts with high mechanical properties, excellent performance, wear-resisting performance, no spark and no magnetic characteristics can replace the more expensive （tin and aluminum） bronze and （lead） brass, and other copper alloy and babbit to manufacture the slider and wear-resisting antifriction parts, such as bearings, bushings, worm gear. As the zinc base alloy melt has the characteristics of low prices, less energy consumption, melt burning pollution-free, wide adaptability and good cutting processability of forming method and a series of advantages, therefore, it has tremendous economic and social benefits to manufacture wear resistance and antifriction parts. Zinc resources are rich in our country, the reserves accounted for a third of the world＇s reserves, the world＇s first, has the advantage of developing zinc base alloy.
