Abstract
Galvanizing on steel surface provides excellent prote-ction to the base metal. The life of galvanized coatings is directly proportional to the thickness of the coatings. Barrier protection plays a vital role in Improving the life of the coated substrate. To improve the quality and the nature of galvanized coating of Zn on steel minor alloying elements such as lead, aluminum, surface passi-vators are added or galvannealing and other treatments are carried out. Zn, Zn-Pb, Zn-Al and interface Zn-Fe alloys are widely used to improve the quality of prote-ctive coatings. In the present work the effect of lead has been studied using potentiodynamics. The quality of the Zn-Pb coating formed is also studied in terms of its adherence and other mechanical properties.
