摘要：

An accelerated corrosion test method was investigated in order to estimate the service life of coated steel. This test focused on the reduction of the thickness of steel material by reproducing the local corrosion represented by pitting. We investigated the conditions that would quickly cause heavy pitting corrosion by changing the temperature, the concentration of NaCl and the wetting and drying of the steel surface. It was found that pitting corrosion can be reproduced quickly by repeating a wet/dry cycle and locally concentrating an appropriate quantity of NaCl during the test. © 2021 Japan Society of Corrosion Engineering.
