Abstract

Of late, there has been an increase in the application of Metal Matrix Composites (MMCs) as they provide significant mechanical and tribological properties. In tune with the rapid global attention to this composite, this research analysis is an attempt on employing Taguchi method in order to minimize the rate of wear and friction on co-efficiency in aluminium MMC. The study involves in investing the tribological behaviour of aluminium alloy, Al-6063, by reinforcing with silicon carbide and aluminium oxide particles. As such, the investigation was carried out by fabrication the alloy by stir casting process. In addition, wear test was performed to analyse the wear and frictional properties of the metal matrix composites with the aid of a pin-on-disc wear tester. For the purpose of the process in an effective manner, Taguchi technique was adopted to perform the experiments on a fixed plan. Further, in analysing the experimental data, A L₉ Orthogonal array was applied. More analyses such as the influencing effect of higher load applied, higher speed of sliding and distance found in sliding on wear rate, and the friction occurring out of co-efficiency during the process of wearing were carried out by employing ANOVA and regression equation. These measures were used for each response for the abovementioned analyses. The experimental results exhibit that the highest influence is observed in sliding distance, while the speed of load and sliding coming behind it. In order to prove the justification of this study, the experimental results were verified with the tests carried out for confirmation.

Al 6063–SiC–Al2O3 的参数影响和摩擦学行为分析

摘要

最近，金属基复合材料 (MMC) 的应用有所增加，因为它们提供了显着的机械和摩擦学性能。与全球对这种复合材料的迅速关注相一致，这项研究分析是尝试采用田口方法以最大限度地减少铝 MMC 中的磨损和摩擦率。该研究涉及通过用碳化硅和氧化铝颗粒增强来研究铝合金 Al-6063 的摩擦学行为。因此，研究是通过搅拌铸造工艺制造合金来进行的。此外，借助销盘式磨损试验机进行了磨损试验，以分析金属基复合材料的磨损和摩擦性能。为了以有效的方式进行流程，采用田口技术按固定计划进行实验。此外，在分析实验数据时，AL₉应用了正交阵列。采用方差分析和回归方程，进一步分析了更高载荷、更高滑动速度和滑动距离对磨损率的影响，磨损过程中因协同效应而产生的摩擦。这些措施用于上述分析的每个响应。实验结果表明，滑动距离的影响最大，而载荷和滑动的速度在其后。为了证明本研究的合理性，对实验结果进行了验证，并进行了验证试验。
