Comparative Study on Corrosion Behavior of Zinc-Aluminum Coated Steel under Thin Electrolyte Layers

Abstract:

Due to the excellent anticorrosion performance, zinc-aluminum coatings are widely used in a variety of structural applications, and most are exposed to atmosphere especially marine atmosphere. In this paper, weight loss experiment and electrochemical impedance spectroscopy technology were used to comparatively study the corrosion behavior of zinc-aluminum coatings in stimulant marine atmosphere. Experimental results show that the anticorrosion performance of GL coating was better than that of GF coating and the length of drying period had obviously influence on the corrosion behavior of GF and GL coating.
