Corrosion resistance test apparatus and corrosion resistance test method for coated metal material

摘要

To increase the reliability of the corrosion resistance test for a coated metal material 1 formed of a surface-processed film 4 and a metal base material 2 coating the surface processing film.SOLUTION: The present invention includes: an electrode 12 arranged in a region of a coated metal material 1 which is near a surface-processed film 4 by a water-containing electrolyte material 6; and conduction means 8 for flowing a current from the electrode 12 to the metal base material 2 through the water-containing electrolyte material 6 and the surface-processed film 4, the electrode 12 being a perforated electrode with at least one through-hole 12a facing the surface-processed film 4 and being nearly parallel to the surface-processed film 4.SELECTED DRAWING: Figure 1
