Summary:Corrosion is the characteristic degradation of materials by their interaction with the operating environment. One of the essential and widely adopted methods to prevent corrosion is coatings on materials. The present study intends to understand the corrosion behavior of Cr-Cu and Cr-Ag coatings for industrial applications. These mainly include the coating and corrosion tests on the material. The stainless-steel samples were coated by RF magnetron sputtering by applying different voltages. To characterize the coatings, X-ray Diffraction (XRD), scanning electron microscope (SEM) and atomic force microscope (AFM) were performed to study crystallinity, morphology and roughness of the coating. The electrochemical corrosion experiment was also performed to study corrosion resistant nature of Cr-Cu and Cr-Ag coated stainless steel was performed.
