Under-Paint Corrosion

  • Xiaoge Gregory Zhang


Knowledge about painted zinc-coated steels has rapidly accumulated during the past two decades owing to the extensive research and development of more corrosion-resistant car bodies. There are numerous published studies on the corrosion performance and corrosion mechanisms of various painted steel products. This chapter aims to compile the results reported in these studies. The basic characteristics of paint and its function as a physical barrier are briefly described in the first section. In subsequent sections, the tests that are used to evaluate under-paint corrosion are described, and information on the effects of various components in a painted system on the corrosion performance is presented. In the last section, the mechanisms of under-paint corrosion are discussed.
