• 流变铸造不同铁含量过共晶Al-Si合金在干摩擦条件下的磨损行为

  来源： 《中国有色金属学报(英文版)2016年第3期》——林冲 吴树森 吕书林 曾劲彪 安萍

  and oxidation wear is the dominant wear mechanism. Key words: dry sliding wear; hypereutectic Al-Si alloy; rheocasting; Fe-bearing compound; wear mechanism 1 Introduction Hypereutectic Al-Si alloys are widely... of rheocast alloys. As the volume fraction of fine Fe-bearing compounds increases, the wear rate of the rheocast alloy decreases. Moreover, the wear rate of rheocast alloy increases with the increase......
