    摘要： A training method for a machine learning model, and a corrosion estimating method using such a machine learning model, the training method comprising equipping at least one vehicle with at least one corrosion sensor, determining the location of the vehicle thanks to a GPS device provided in the vehicle, determining, in a weather station database, which weather station is the closest to the location of the vehicle, retrieving at least some weather data from said closest weather station, retrieving at least some corrosion data from said at least one corrosion sensor, building a training database (20) associating, for several moments over at least ten days, said corrosion data with said weather data, and training the machine learning model (30) on the training database (20) thus built.

    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.
