摘要：
The electrochemical behaviors of the zinc-rich paints based multilayer organic coatings in 3.5% NaCl solution were studied. The results show that the zinc powder has a minor cathodic protection effect. The protection effect is due to the repair of holes by the corrosion product of zinc powder. Under the epoxy topcoat, the corrosion rate of the zinc powder in inorganic zinc-rich coatings is faster than that in organic type.
