Abstract

Fly ash particles are potentially used in metal matrix composites due to their low cost, low density, and availability in large quantities as waste by-products in thermal power plants. This study describes multifactor-based experiments that were applied to research and investigation on dry sliding wear system of stir-cast aluminum alloy 6351 with 5, 10, and 15 wt.% fly ash reinforced metal matrix composites (MMCs). The effects of parameters such as load, sliding speed, and percentage of fly ash on the sliding wear, specific wear rate, and friction coefficient were analyzed using Grey relational analysis on a pin-on-disc machine. Analysis of variance (ANOVA) was also employed to investigate which design parameters significantly affect the wear behavior of the composite. The results showed that the applied load exerted the greatest effect on the dry sliding wear followed by the sliding velocity.
粉煤灰增强AA-6351金属基复合材料干滑动摩擦磨损研究
粉煤灰颗粒由于其低成本、低密度和可大量用作火力发电厂的废副产物而具有用于金属基复合材料的潜力。本研究描述了基于多因素的试验,应用于5、10和15 wt搅拌铸造6351铝合金干滑动磨损系统的研究和调查。%粉煤灰增强金属基复合材料(MMCs)采用灰色关联分析方法,分析了载荷、滑动速度、粉煤灰掺量等参数对销盘式机床滑动磨损、比磨损率和摩擦系数的影响。方差分析(ANOVA)也被用来调查哪些设计参数显著影响复合材料的磨损行为。结果表明,外加载荷对干滑动磨损的影响最大,其次是滑动速度。
