In order to evaluate the effectiveness of inoculating Fly Ash (FA) into aluminum composites to increase their functionality, the wear properties of AA6063/Silicon Carbide (SiC) /Fly Ash composites under varied loads are characterized. In this study, authors use a stir casting method to inoculate Fly Ash into AA6063/SiC functional composites with various blends of reinforcements (0.5, 1 & 1.5 wt.%). The innovative aspect of this study is the use of Fly Ash as a functional inoculant, which, coupled with the SiC, is sure to affect the composites’ tribological properties. Several process factors were investigated to establish how they influenced the wear characteristics of the produced composites, with consideration given to the real-time operating demands of the composites in question from the prior research investigations. The percentages of SiC and Fly Ash weights, as well as the distance and speed at which the load was slid, were also considered. The wear regimes that emerge from characterizing the samples at various loads are then employed in an analysis of variance (ANOVA) to provide statistical support for the experimental findings. The findings provide substantial support for the hypothesis that immunization can reduce wear rate. At a load, sliding velocity, sliding distance of 20 N, 6 m/s and 3000 m, respectively, the L27 experimental trial yielded a wear rate (WR) of 0.00118 mm3/m and a coefficient of friction (COF) of 6.8783 for composite synthesized by reinforcing each 1.5 wt.% of SiC, and Fly Ash. Micro isolation of silicon carbide and homogenous distribution of FA to the AA6063 are responsible for the composite's enhanced tribological properties.

摘要

In order to evaluate the effectiveness of inoculating Fly Ash (FA) into aluminum composites to increase their functionality, the wear properties of AA6063/Silicon Carbide (SiC) /Fly Ash composites under varied loads are characterized. In this study, authors use a stir casting method to inoculate Fly Ash into AA6063/SiC functional composites with various blends of reinforcements (0.5, 1 & 1.5 wt.%). The innovative aspect of this study is the use of Fly Ash as a functional inoculant, which, coupled with the SiC, is sure to affect the composites’ tribological properties. Several process factors were investigated to establish how they influenced the wear characteristics of the produced composites, with consideration given to the real-time operating demands of the composites in question from the prior research investigations. The percentages of SiC and Fly Ash weights, as well as the distance and speed at which the load was slid, were also considered. The wear regimes that emerge from characterizing the samples at various loads are then employed in an analysis of variance (ANOVA) to provide statistical support for the experimental findings. The findings provide substantial support for the hypothesis that immunization can reduce wear rate. At a load, sliding velocity, sliding distance of 20 N, 6 m/s and 3000 m, respectively, the L27 experimental trial yielded a wear rate (WR) of 0.00118 mm3/m and a coefficient of friction (COF) of 6.8783 for composite synthesized by reinforcing each 1.5 wt.% of SiC, and Fly Ash. Micro isolation of silicon carbide and homogenous distribution of FA to the AA6063 are responsible for the composite's enhanced tribological properties.
