Evaluation of Electrochemical Properties of Steel Sheets for Automotive Applications

摘要

Galvanizing as a process of zinc coating of base material is still the most widely used technology applied in surface treatment of materials which are supposed to meet the requirement of high corrosion resistance in various environments. This article presents the results of research aimed at determining the corrosive properties of galvanized sheets in selected environments - distilled water, NaCl and SARS (Simulated Acid Rain Solution) solution, using electrochemical potentiodynamic test and electrochemical impedance test (Electrochemical Impedance Spectroscopy -EIS).
