Abstract
The method for a corrosion resistance test of a coated metal material is an electrochemical method simulating corrosion proceeded by damaged portions in the surface treatment film. Two artificially damaged portionsspaced from each other in a coated metal materialthat is obtained by providing a surface treatment filmon a metal baseare electrically connected to each other by an external circuitvia an aqueous electrolyte material, and corrosion proceeds by supplying current using one of the artificially damaged portionsas an anode site and the other as a cathode site.
