Hydrogen Permeation Characterization of Hot-Dip Galvanized Steel in Simulated Marine Atmospheric Environment

Abstract:

Article Preview

Hydrogen permeation current curve of galvanized steel with hot-dip zinc coating exposed to simulated marine atmosphere was measured using a modified Devanathan-Stachurski cell. Effect of temperature, humidity and coating defect on its hydrogen permeation behaviour was also investigated. The results indicated that hydrogen permeation current density and the amount of hydrogen accumulated increased evidently with temperature and humidity rising at moist environment; meanwhile, hydrogen absorption when coating defect occurred was accelerated by the cathodic protection of the exposed steel surface afforded by surrounding zinc coating.
