ZINC COATINGS ON STEEL SUBSTRATE ATTAINED BY DIFFERENT ELEMENTS ADDED
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
The purpose of this work was to identify the influence of different process variables, such as bath temperature, immersion time and bath alloy additions, on the morphology and coating thickness attained using innovative alloys systems containing different percentages of Ni, Pb, Sn and Bi. Steel samples were galvanized by the hot-dip method in micro alloyed zinc baths at different temps and temperatures Experiments were aimed to obtain zinc coatings with increased resistance to corrosion, which adheres very well to steel support, not conducive Fe-Zn reactions, not have negative environmental impacts and presents uniformly dispersed phase structure in zinc matrix. Layers obtained in micro alloyed zinc with nickel, bismuth, tin, lead are analyzed.
