摘要
利用粉末冶金法制备了不同烧结温度的Si Cp增强Al-Si基复合材料,用X射线衍射仪、布氏硬度计、ML-10摩擦磨损机、扫描电镜等对样品的物相组成、布氏硬度、磨损性、表面形貌等进行表征。结果表明,随烧结温度的提高,试样的密度和硬度先增大后减小,烧结温度为590℃时试样的密度和硬度达到最大值,最大硬度为81 HBW。试样的耐磨性随烧结温度的增加先增大后减小,烧结温度为590℃的样品具有最好的耐磨性。
Aluminium-silicon-based composite materials reinforced by SiCp were synthesized by powder metallurgy. The phase, Brinell hardness, wear resistance and surface morphology were tested by X-ray diffractometer, Brinell hardness tester, ML-10 type wear testing machine and scanning electron microscope, respectively. The results show that with increasing the sintering temperature, the density and hardness increase and then decrease. The maximum hardness of sample synthesised at 590 ℃ is 81 HBW. The wear resistance increases and then decrease as the sintering temperature increases. The sample sintered at 590 ℃ has the best wear resistance.
