New electrochemical method for the determination of the barrier properties of corrosion protective coatings

A novel electrochemical method evaluates the durability of corrosion protective coatings by measuring the galvanic current between a coated AZ31 Mg alloy and a Pt auxiliary electrode in a 2 M NaCl solution. In this work an organo-inorganic sol-gel film was used. The durability criterion, t, was sele...
