Details

This new book examines the atmospheric corrosion behavior of aluminum killed carbon steel with copper and chromium additions, galvanized and ungalvanized. All steels were phosphatized and painted in an industrial plant. The corrosion resistance evaluation was carried out using accelerated tests and field tests at industrial weathering sites. The average cosmetic corrosion results, obtained in the field test during a 24 month period, with an application of a saline solution spray, were similar to those of the General Motors 9540P/B cyclic test with 40 cycles. The corrosion mechanism was evaluated, and the role that chromium and copper play in corrosion processes was discussed. (Imprint: Nova)
