As competition among global automakers intensifies, demand for materials that are better in price and performanceis increasing. While steel and plastic materials compete for automotive fuel tanks, plastic materials haveadvantages such as light weight for automobiles. However, they have high prices. Accordingly, in this paper,four types of Zn-X plated steel sheets, electroplating (X = none, Sn) and galvannealed (X = Fe, Fe-Mg),were manufactured and their applicability as a fuel tank material was evaluated. Nano-composite coatingsolution with good conductivity was treated on the surface of plated steels using a roll coater and thencured through induction furnace to improve corrosion resistance. Quality characteristics such as corrosionresistance, fuel resistance to diverse gasoline and diesel fuels, and seam weldability were evaluated for theabove plated steels. Their properties were compared and analyzed with conventional Zn-Ni electroplatingsteels. Among the above plated steels, Zn-Fe-Mg galvannealed steels coated with nano-composite coatingexhibited better properties than other steels. Detailed experimental results suggest that evenly distributedMg elements on the coating layer play a key role in the enhanced quality performance.
