Abstract
In the present study, an effort has been taken to fabricate and compare the erosion-corrosion of aluminium alloy (ADC12) based composite as ADC12-7%SiC and ADC12-7%TiB2 in Basic, Acidic, Seawater and Aqueous atmosphere. TiB2 reinforced composite revealed better hardness when compared to that of SiC composite. Erosion-corrosion of aluminium alloy composites were performed at different erodent concentrations (40, 60, 80 wt%) and a speed of 1000, 1500 revolution per minute. It is marked by the study that composites show ameliorate wear resistance than alloy at all speeds and all concentrations except in Basic medium. Microstructural analysis elicited Al-Si interfaces to be a preferential site for corrosion attack. Addition of reinforcement reduces the metallic area for erodent attack; hence composites show less material loss than the alloy. Among composites, TiB2 reinforcement composite show ameliorates wear resistance irrespective of speed, slurry concentration, and slurry medium. However, regardless of the material, the material loss at 1000 rpm is more than 1500 rpm in Basic media. Based on the analysis, Material removal has the following order in different mediums as; Basic > Acidic > Marine > Water.
