| Research Abstract |
To maintain the infrastructure made from steel, the accelerated corrosion test and the evaluation of corrosivity were developed. Because an atmospheric environment was able to be defined by the amount of the sea salt and wet conditions, the device which was able to put the sea salt was developed. The effect which the amount of the sea salt induced on corrosion was examined under the environment by which the temperature and humidity were controlled. The detailed condition will be examined in the future. The evaluation of corrosivity was conducted by exposing galvanized steel. The rust area rate of the galvanized steel has grown by the amount of corrosion of steel large. As a result, the evaluation of corrosivity will become to be easy.
