Al6061-Basalt and Zircon Hybrid composite Material Corrosion Resistance in Acid Media

Abstract

The present investigation is an attempt made to develop Al6061/Basalt/Zirconium oxide Hybrid Metal Matrix Composites (MMCs) by liquid metallurgy technique (stir casting) and to study the wear properties of Al6061/Basalt/Zirconium oxide reinforced hybrid metal matrix composites. The composite is prepared by using Liquid Metallurgy Route (Stir Casting Technique), although other processing technique such as powder metallurgy delivers better mechanical properties in MMCs, Liquid state has some significant focal points, for example, better matrix molecule holding, simpler control of matrix structure, ease of handling, closer to net shape and wide choice of material. Al6061 is taken as a base material (matrix) and Basalt (1– 10%) and Zirconium oxides (2%) are used as reinforcements. Corrosion analysis for Aluminum Metal Matrix Composites (MMCs) was done in acid (HCl) media at room temperature & different time intervals. The results were tabulated & it was found that the MMC containing 4% basalt underwent maximum corrosion at room temperature. SEM is done for all the samples the results are tabulated.
