Abstract Scope |
Aluminum alloys have been used as pre-painted composite panel materials in the building sector for years, thanks to their mechanical properties and lightness. Since these materials are constantly in contact with the open atmosphere, corrosion resistance must be at a certain level. In industry; in order to evaluate the corrosion resistance of painted composite panels, long-term salt spray corrosion tests are carried out. These tests can take up to 1000 hours. In this study; painted productions were made from two alloys developed as an alternative to conventionally used aluminum composite panel alloys. Corrosion tests were carried out with the Tafel Extrapolation method, which is one of the short-term electrochemical corrosion test methods. The results obtained from these tests were compared with the salt spray test results. In corrosion resistance measurements; a correlation was observed between the conventional salt spray method and the electrochemical Tafel Extrapolation method. |
