以粉煤灰泡沫陶瓷作为增强相,以铝硅合金作为基体材料,采用挤压铸造工艺制备出粉煤灰泡沫陶瓷铝硅合金复合材料。研究了相同浇注温度不同基体材料以及同种基体材料不同浇注温度因素下复合材料界面结合的情况。结果表明,以亚共晶铝硅合金(ZL101)、共晶铝硅合金(ZL102)和过共晶铝硅合金(Al-23Si)作为基体材料均能制备出界面结合良好的复合材料,并且界面之间形成了一组织紧密的硅相过渡带；粉煤灰泡沫陶瓷铝硅合金复合材料的界面结合机构是机械联锁结合、存在扩散层和界面反应的混合机构；铝硅合金与粉煤灰泡沫陶瓷的界面结合能力随着温度的升高而提高,在温度低于780℃的情况下,界面易出现分离现象,780~810℃为较佳浇注温度。

Co-continuous fly ash/Al-alloy composites were fabricated by squeeze casting method.Fly ash ceramic foam and Al-Si alloy were selected as the reinforcement and the matrix material,respectively.The interface bonding of the composites was studied at the factor of different matrix material and pouring temperature.The results show that the composites with well interface bonding can be fabricated as the hypoeutectic Al-Si alloy (ZL101),eutectic Al-Si alloy(ZL102)and hypereutectic Al-Si alloy(Al-23Si)are chosen for the matrix materi-al.A transition zone with compact silicon phase is formed in the interface.The mechanism of the composites’ interface bonding is mixed,it exists mechanical interlock permeating layer and interfacial reaction.The bonding capacity of Al-Si alloy and fly ash ceramic foam increases with the increasing of temperature.Under the condi-tion of the temperature is below to 780 ℃,the interface was easy to separate.The appropriate pouring tempera-ture was 780-810 ℃.
