Abstract: Elastic metal elements are essential to vehicle safety, durability, and performance, yet their continuous exposure to dynamic loads and harsh environments makes them highly susceptible to corrosion. While corrosion resistance can be addressed through material selection at the design stage, practical and economic constraints often necessitate the use of protective surface treatments. This review summarises current strategies for improving the corrosion resistance and functional performance of automotive elastic components, comparing key coating technologies-such as phosphating, electrochemical oxidation, galvanising, and organic coatings-and highlighting their respective benefits and limitations under service conditions.

Keywords: corrosion protection, elastic metal elements, automotive industry, surface treatment, material resistance, protective coatings
