Abstract

A gearbox for an automobile comprises a lower box body and an upper box body, wherein the lower box body and the upper box body are connected to form a gearbox cavity, the inner surface of the upper box body is coated with an aluminum oxide series ceramic material layer, the inner surface of the lower box body is coated with a zirconium oxide series ceramic material layer, and the outer surface of the upper box body and the outer surface of the lower box body are coated with organic silicon coatings. Due to the fact that the inner surface of the lower box body makes contact with gearbox oil more easily than the inner surface of the upper box body, differentiated coating is conducted on the inner surface of the lower box body and the inner surface of the upper box body, corrosion resistance is improved, and the organic coatings are formed on the outer surfaces of the box bodies to effectively improve weather resistance and staining resistance.
