| 摘 要： | 以粒度为80μm的粉煤灰为增强相,粒度为30μm的铝粉为基体,采用粉末冶金法成功制备了粉煤灰颗粒增强铝基复合材料。经SEM、金相显微镜等分析手段对制备的复合材料进行组织观察,并对其进行耐磨性测试。结果表明,粉煤灰含量为20%,烧结温度为650℃时,相对损率最小为0.1590%。随着粉煤灰含量和保压时间的增加,试样的耐磨性逐渐升高,随着烧结温度升高,试样的耐磨性呈现出先升高后降低的趋势。

| Abstract: | The powder metallurgy technique was used to prepare fly ash particle reinforced aluminum matrix composites. The microstructure of prepared composites was observed by SEM, metallographic microscope analysis, and has carried on the wear resistance test. The results indicated that fly ash content of 20%, 650℃sintering, minimum relative wear rate is 0. 1590%. Wear resistance of the composites increased significantly with the increase of fly ash particles content and the time of holding pressure, while increased further and then declined with the increase of the sintering temperature. |
