. These heavy metals do not only catalyse the surface reactions but generate a more corrosion resistant surface. We perfected the trecation phosphate solution by reducing the sludge, accelerating... the cathode-electrophoretic painting processes causing the result that the coatings adhesion, corrosion protection, alkaline resistance are decreased. Furthermore,the service life of the coated production......
