Comparative Study on A Novel Local Electroplating Method Using High-Density Paste Versus Traditional Electrolytic Solutions: An Examination of Copper Coating Thickness and Corrosion Resistance on Iron Samples

Abstract

This paper presents a study on a new method of electroplating, using a high-density paste instead of traditional electrolytic solutions. The method was tested on iron samples, which were coated with copper. The thickness of the copper layer was measured using a leoi-44 experimental ellipsometer, revealing a thickness of 318 nm for the sample treated with the paste method, and 400 nm for the sample treated traditionally. The corrosion resistance of the samples was also tested, showing similar results for both methods. The paper concludes that this new method could be useful for treating specific areas of large or fixed metal objects, such as tanks or pipelines, and for artistic decoration on metals introduction.
