摘要

本文讨论了石墨粉对铝熔体磨损和摩擦性能的影响。采用搅拌铸造技术制备了铝-石墨复合材料。具有2重量%、4重量%和6重量%的三种不同量的石墨颗粒用于复合材料的制造。根据ASTM-G99在铝-石墨（Al-Gr）复合材料和软钢摩擦副之间进行销-盘实验。获得了磨损的Al-Gr复合材料的扫描电子显微镜图像，以研究该复合材料的磨损。据观察，石墨颗粒有助于降低铝的磨损和摩擦系数。

Wear and friction behaviour of aluminium metal composite reinforced with graphite particles

Present paper discusses the effect of graphite powder on the wear and friction properties of aluminium melt. The aluminium graphite composite was fabricated using the stir casting technique. Three different amounts of graphite particle with 2 wt. %, 4 wt. % and 6 wt. % are used for the fabrication of the composite. Pin on disc experiments were performed as per ASTM-G99 between aluminium graphite (Al-Gr) composite and mild steel tribopair. Scanning electron microscope images for the worn Al-Gr composite were obtained to study the wear of the composite. It is observed that graphite particles help in reducing the wear and friction coefficient of the aluminium.
