Description
Summary:The corrosion resistance of composite nickel electrodeposits with alumina embedded in the nickel matrix prepared in sulfate and chloride bath has been studied. As corrosion environment salt spray and nitric acid solution have been tested. The chloride type of deposits were more resistant in the corrosive environments studied than the sulfate ones. The structure as a consequence of the preparation conditions affect the corrosion resistance behavior of the deposits. The composite deposits with aluminium oxide exhibited a higher corrosion resistance in all tested conditions.
