Abstract
The application relates to an aluminum alloy hub and a method for coating the surface of the aluminum alloy hub. The aluminum alloy hub is provided with an aluminum alloy matrix and a coating attached to the surface of the aluminum alloy matrix, and the coating sequentially includes a pre-coating layer formed by nickel-coated aluminum or aluminum-coated nickel powder, a CrClayer and a varnish layer on the surface of the aluminum alloy matrix. According to the aluminum alloy hub disclosed by the invention, more excellent corrosion resistance is obtained by spraying the CrClayer on the surface of the aluminum alloy hub.
