| Abstract |
The purpose of this study was to identify the corrosion mechanism of painted steel sheets and to examine the change of temperature. In order to carry out the experiment, the painted steel sheet was prepared as a test group, and each specimen was corroded under different temperature conditions and observed with a Scanning Electron Microscope with Energy Dispersive Spectroscopy (SEM/EDS). However, it is difficult to observe the experiment in the general environment, because the corrosion rate is slow. So we set up the experiment to be smooth through two methods.
First, scribe was applied to the specimens to the same extent so that the corrosion reaction proceeded faster.
Second, the experimental environment was set so that salt water was sprayed at a constant pressure and speed using a SST (Salt Spray Test) analysis machinery.
Through this experiment, it is possible to observe the corrosion reaction and the change stage, and to understand the relationship between temperature and corrosion degree.
