摘要
研究了悬浮铸造对粉煤灰漂珠颗粒增强铝基复合材料组织性能的影响。结果表明:加入与基体同种成分不同量的悬浮剂,复合材料(漂珠体积分数为5%)的硬度提高,但强度和塑性有所下降;当加热温度为800℃、加入量为3%时,硬度与耐磨性分别增加13.10%和20.10%,强度和伸长率则分别降低了23.80%和43.54%。
The effects of suspension casting on the microstructure and properties of fly-ash floating beads particle reinforced aluminum matrix composite were studied. The results show that adding suspending agent with the same composition to aluminum can improve the hardness of aluminum matrix composite containing 5vol% fly-ash floating beads particle. When the addition temperature is 800℃ and addition quantity of suspending agent is 3%, the mechanical properties （σb, δ） decrease. The hardness and wear resistance of fly-ash floating beads particle reinforced aluminum matrix composite can be increased by 13.10% and 20.10%, the mechanical properties （σb, δ） are decreased by 23.80% and 43.54%.
