利用立式高频感应炉制备出3组不同B含量的铸造Pb-Mg-10Al合金,并对其摩擦磨损性能进行了研究。采用X射线衍射仪分析物相,用扫描电镜观察其显微组织。结果表明,随着B的添加,合金组织中出现了陶瓷相AlB2颗粒,由于陶瓷相的增多,合金的硬度得到显著提高。室温滑动摩擦磨损试验表明,合金的耐磨性能随B含量的增加而增加,当B含量为2%时,其磨损量和摩擦因数最小。 Three sets of cast Pb-Mg-10Al alloys with different content of B were prepared by vertical high-frequency induction furnace, and their friction and wear properties were studied. The phase was analyzed by X-ray diffraction and the microstructure was observed by scanning electron microscopy. The results show that with the addition of B, the ceramic phase AlB2 particles appear in the alloy. Due to the increase of the ceramic phase, the hardness of the alloy is significantly increased. The results of sliding friction and wear tests at room temperature show that the wear resistance of the alloy increases with the increase of B content. When the B content is 2%, the wear resistance and friction coefficient are the least.
