Vehicle corrosion reduces the life cycle and safety performance of the vehicle, thereby resulting in huge social corrosion costs. For this reason, the automobile companies try to apply advanced materials and structural designs to achieve an anti-corrosion performance during the design phase. In this study, corrosion resistance and corrosion behavior of uncoated cold-rolled steel and zinc-coated steels(e.g., Zn-coated and Mg-Zn-Al-coated steels) were compared by using the salt spray test(SST) and cyclic corrosion tests(CCTs), such as the GMW14872, ISO14993, and VDA233-102. The corrosion rates of both steel and zinc were calculated from the weight loss measurements and corrosivity comparison that were conducted in these accelerated tests. The acceleration of each corrosion test was quantified by comparing with the actual field corrosion data.Read More
