Abstract

In the present work, the mechanical, tribological behavior of the machinability using electro discharge machining on a hybrid reinforced with different compositions of SiC and glass particulates are fabricated through a stir casting route. The effect of composition with machine parameters on the responses was observed. The Taguchi L9 orthogonal array was used for conducting the experiments, and the optimal EDM machining condition was obtained by performing MULTI-MOORA method integrated with PCA method. However, the effect of load, speed, and composition was investigated for tribological properties. It has been observed that SiC and glass particulates, significantly affect the compressive strength and hardness. However, the impact energy reduces an increase in the brittle nature of the composite. The glass particles do not contribute to the tensile strength but significantly improve the tribological property. The composition and pulse current found to be the most influencing parameters, the composition (Al- 2014+2wt% glass+3 wt% SiC) has led to the best combination for machinability.

Composite

A composite material obtained by two or more different materials, with different physical and electrical properties, predictors than the properties of the resulting material are superior. Usually comprised of two phases: the reinforcement phase, and the matrix phase, Vlot and Gunnink (2011). Each material has different physical, mechanical and chemical properties, its properties depend on the composition of the particles and, consequently, the level of dispersion of the mixed particles is a factor that determines the properties of the compounds. The factor that also affects the properties of composite materials is the interface between the host matrix and the particles. it is made of a base material called matrix, has low properties while being affordable, reinforced with different materials in the form of continuous fibers, short fibers or particles with mechanical, physical properties or chemical Helu et al. (2011).
