This experimental study is devoted to characterization, corrosion behavior effect of temperature and inhibition on AA 6351 frictional surfaced mild steel substrate (IS2062) by controlling the process parameters like spindle speed, traverse speed and axial load. The developed samples were analyzed using SEM, EDAX and XRD techniques. Corrosion resistivity of the coated samples were studied in the presence of 1 N acidic, basic and 1 M salt corrosive environments for 48 h by weight loss method. Based on the weight loss results, the samples were further investigated to confirm the effect of temperature interface by heating the samples gradually from 300 °C to 600 °C and good binding nature was exposed on the coated materials. EDAX confirmed the alloy components at 1.50, 6.38, 6.42 and 7.04 keV. Similarly, XRD confirmed the peak of base and coated metals components at 38.5, 44, 55.10, 78.3, 82.4, 99.03, 112.13, and 116.66 respectively. Corrosion inhibition of selected samples for 48 h was examined. The results were tabulated and recorded after thorough analysis. It was observed that the inhibition efficiency is found to be moderate for cowries when compared to tamarind seeds in sodium chloride solution based on the conductance study.
