CORROSION RESISTANCE TEST APPARATUS AND CORROSION RESISTANCE TEST METHOD FOR COATED METAL MATERIAL

摘要

A corrosion resistance test apparatus 100 is for a coated metal material 1including a steel sheet 2 and an electrodeposition coating film 4 provided on the steel sheet 2. The corrosion resistance test apparatus 100 includes: two water-containing material holders 11 disposed on the electrodeposition coating film 4 to hold a water-containing material 6 that is in contact with the electrodeposition coating film 4 inside; two electrodes 12 in contact with the water-containing material 6 contained in each of the two water-containing material holders 11; an external circuit 7 configured to electrically connect between the two electrodes 12; a temperature control element 41, 43 that is brought into contact with the coated metal material 1 via an insulating portion 42, 44 and is configured to control a temperature of at least the coated metal material 1; a control device 9 connected to the temperature control element 41, 43 and configured to control a temperature of the temperature control element 41, 43; and a current supplier 8 provided on the external circuit 7 and configured to supply a current between one of the two electrodes 12 and the other, as an anode and a cathode, respectively to bring corrosion of the coated metal material 1 to progress.
