Abstract: A pretreatment process for a magnesium alloy wheel is provided. The process flow is as follows: washing with hot water; degreasing; washing with hot water; acid washing for surface adjustment; washing with water; washing with pure water; performing chromium-free conversion treatment; washing with pure water; washing with pure water; sealing film; washing with pure water; baking; and spraying (electrophoresis). The process of the present invention can improve corrosion resistance of magnesium alloys and adhesion of surface coating thereof, realizing durable use of the surface of the magnesium alloy wheel. An immersion type treatment is adopted in the pretreatment, and therefore the process time is short, and the formed film is uniform and has good compactness. Application standard for corrosion-resistance of wheels can be reached by combining the pretreatment process with spraying and electrophoresis.
