Description
Summary: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.
