摘　　要：以煤炭生产废弃物煤矸石为原料,在煅烧和球磨后按不同质量分数(5%~35%)与不同粒度铝粉(5μm,45μm)混合,经过烧结制备了陶瓷增强铝基复合材料。研究了煤矸石添加量和铝粉粒度对陶瓷增强铝基复合材料的相组成、机械性能和微观结构的影响。结果表明:交错柱状莫来石和网状交错氮化铝晶须起到增强作用;随着煤矸石的加入,陶瓷相含量增加,煤矸石的加入使材料内部孔隙增多,主要原因是它在加热时发生反应,导致体积变化。该研究为陶瓷增强复合材料的制备及煤矸石的再利用提供了重要参考价值。The coal production waste coal gangue after calcination and ball milling with different mass fractions(5%~35%)were mixed with aluminum powder(5μm,45μm),and were sintered to prepare ceramic reinforced aluminum matrix composite.The effects of coal gangue addition and aluminum particle size on the phase composition,mechanical properties and microstructure of ceramic reinforced aluminum matrix composites were studied.The results show that the staggered columnar mullite and the reticulated staggered aluminum nitride whisker play an enhanced role.With the addition of coal gangue,the content of ceramic phase increases,and the addition of coal gangue increases the internal pores of the material,mainly because it reacts when heated,resulting in volume change.This study provides important reference value for the preparation of ceramic reinforced composite materials and the reuse of coal gangue.
