- Description
- The purpose of this work is to ascertain development and wear characteristics of hybrid aluminum composites (Al7075) reinforced with silica particles and boron fiber, which could lead to application within high-performance applications. Hybrid composites fabricated by using the liquid metallurgy. Silica content was varied at 0%, 2%, 4%, and 6% by weight, while the boron fibers were used at 1%, 3%, 5%, and 7% by weight. The dry sliding conditions wear tests were executed with the following parameters: load (1040 N) & sliding velocity (0.52.0m/s). Results showed that the composites with 4% silica and 5% boron fibre revealed a 28% decrease in wear loss at 10 N compared to Al7075, indicating a maximum improvement in wear resistance. By performing statistical analysis with ANOVA, the loads were found to be the major contributor of 48.02% to wear loss, followed by silica content and sliding velocity as 24.91% and 22.38%, respectively. SEM confirmed uniform dispersion of reinforcement, very low porosity, and good interfacial bonding. It is observed that hybrid Al7075 composites exhibit enhanced strength and wear resistance, thus well suited for severe applications requiring light weight, tough materials.
