Characterization of Nanostructure Black Nickel Coatings for Solar Collectors

Abstract

Abstract:In this research, black nickel coatings have been deposited on brass, copper and steel substrates by electrodeposition method. The physical properties of solar absorber black nickel coatings on different metallic surfaces have been investigated. The effect of different metallic substrates including brass, copper and steel with presence of bright nickel middle layer and without its presence on optical and structural properties of deposited layers have been studied. These coatings characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive X-ray analysis (EDAX). For investigation of optical properties of deposited layers, UV-VIS-NIR spectrophotometer was used.
