adhesion, corrosion protection of metals, electrical discharge preparation of metal surfaces, metal corrosion, paint coatings


Spark machining of steel surfaces enhances the subsequent paint coatings adhesion and protective properties. These factors improvement was confirmed at the salt-spray chamber testing and by both adhesion to the surface and depth of corrosion penetration below the paint coating layer measurements.
