The invention relates to an aluminum alloy hub and a method for coating the surface of the same. The aluminum alloy hub comprises an aluminum alloy matrix and a coating attached to the surface of thealuminum alloy matrix, wherein the coating sequentially comprises a pre-coated layer formed by nickel-clad aluminum or aluminum-clad nickel, a Cr3C2 layer and a varnish layer on the surface of the aluminum alloy matrix. By spraying the Cr3C2 layer on the surface of the aluminum alloy hub, the aluminum alloy hub obtains excellent corrosion resistance.

本申请涉及一种铝合金轮毂及对其表面涂层的方法。所述铝合金轮毂具有铝合金基体和附着在所述铝合金基体表面上的涂层，所述涂层在所述铝合金基体表面上依次包括由镍包铝或铝包镍粉末形成的预涂层、CrC层和清漆层。本发明的铝合金轮毂，通过上述对铝合金轮毂表面喷涂CrC层获得了更优异的耐腐蚀性能。
