Corrosion Resistance of WC-Cu Coatings Produced by Electrospark Deposition

The main objective of the present work was to determine the influence of laser treatment on corrosion resistance of coatings deposited on C45 carbon steel by the electro-spark deposition process. The studies were conducted using WC-Cu electrodes produced by the powder metallurgy route. The technology uses the phenomena of electrode material erosion and spark discharge between the electrodes, leading to the formation of a surface layer with characteristics different from those of the substrate. The use of these protective layers provides optimum resistance to corrosion.
