Effects of SiC, Al2O3, and ZrO2 Particles on the LBMed Characteristics of Al/SiC, Al/Al2O3, and Al/ZrO2 MMCs Prepared by Stir Casting Process

The effects of SiC, Al2O3, and ZrO2 particles on the characteristics of Al/SiC, Al/Al2O3, and Al/ZrO2 metal matrix composites (MMCs) have been studied in the present research work. The comparison of machining characteristics has been done to analyze the behavior of various reinforced particles with the variation of laser machining variables. The output characteristics such as dross height and kerf deviation have been investigated and compared with each MMCs. SEM and XRD have been used for the investigation of morphological changes in the structure and agglomeration of reinforced particles. The crack and recast layer formation has been examined in the specimens of higher quantity of reinforced particles. It was observed that the MMC material reinforced with SiC particles has shown different behavior as compared to other MMC materials.
