摘要：

The corrosion protection of poly ethylmethacrylate coatings on tin-free steel in contact with 0.1 M HCI has been examined using electrochemical impedance spectroscopy. The coatings were formed from latices of different particle size. The quality of the coating increases with decreasing particle size of the latex, and the larger particle size films all have defects in them which allow the electrolyte to contact the underlying metal. The fraction of the underlying metal which is wetted is 10(5) greater than the porosity of the coatings.
