A Research on Effect of Metal Coupling on Rusting of Iron

Abstract: This research reinforces the importance of material selection and galvanic coupling in preventing or controlling corrosion in real-world applications. So metal coupling has become the most important research going on regarding various issues of corrosion. So this project is regarding one of the most remarkable techniques “METAL COUPLING” for prevention of corrosion. In this project we are looking forward to investigate the effect of the metal coupling on the rusting of iron, so here we have taken the metal strips ofzinc, copper, and aluminium. Metal coupling affectsthe rusting of iron according to the ECS series, if the nail is couple with the more electropositive element or metal like zinc and Aluminium rusting is prevented but if on the other hand It is couple with less electropositive metal like copper and nickel the rusting is facilitated.
