A Metallurgical Approach to the Cracking Resistance of Hot-Dip Galvanized Zinc Coatings

Abstract

The texture of zinc coatings influences to a large extent their formability, due to the anisotropic properties of zinc. The (0002) basal plane is the easiest slip plane in zinc crystal. Its inclination to the deformation axis and direction directly influences the deformation behaviour. This work deals with the effect of the texture and microstructure on the cracking behaviour of zinc coatings. For this purpose, twelve different commercial hot-dip zinc coatings have been studied.
