【摘要】 利用挤压铸造法制备了Al₂O₃和C短纤维混杂增强ZL109金属基复合材料。并讨Al₂O₃和C短纤维含量对该混杂复合材料钻削加工性的影响进行了研究,考察了切削用量、纤维位向对钻削力、刀具磨损和钻削精度的影响规律,并对其影响机理进行了分析。结果表明:从刀具磨损角度出发,该混杂复合材料的钻削加工性次于45钢和基体合金。更多还原

【Abstract】 Al2O3f + Cf/ZL109 short fibers reinforced hybrid metal matrix composites were fabricated by squeeze casting. The effects of alumina and carbon fibres volume content on the drilling machinability of the hybrid composites were researched . The influences of quantity used in cutting and orientation of fiber on drilling force, tool wear and drilling precision were investigated,and the mechanism was analyzed. The conclusion can be drawn that according to the drill wear, the machinability of Al2O3f + Cf/ZL109 is inferior to 45 steel and ZL109 alloy.更多还原
