Electrochemical deposition of nickel coatings from acetate-chloride electrolyte in pulse mode

Abstract

The process of electrodepositing of nickel from acetate-chloride electrolyte at low temperature in a pulsed mode has been investigated. It is established that application of pulsed electrolysis mode allows to increase the working current density up to 9 A/dm2. A nanostructured nickel coating with a maximum size of crystallites of 200 nm is obtained. The results show that the use of pulsed electrolysis makes possible to reduce porosity of coating thicknesses up to 20 ?m.The process of electrodepositing of nickel from acetate-chloride electrolyte at low temperature in a pulsed mode has been investigated.
