摘要：
We developed a new accelerated corrosion test for evaluating the corrosion resistance of coatings. The new test was designed to approximate the water absorption and desorption behavior of anti-corrosion coatings in actual outdoor environments. This test makes it possible to well approximate atmospheric corrosion in seafront areas and to accelerate the corrosion of steel and zinc by around 1.4 times compared with the conventional method. This test will make it possible to efficiently and accurately select coatings in a shorter test time. Consequently, the maintenance cost of steel structures can be reduced by selecting the appropriate coatings. ©© 2023 Nippon Telegraph and Telephone Corp.. All rights reserved.
