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 Cr.sub.3C.sub.2 layer 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 Cr.sub.3C.sub.2 layer on the surface of the aluminum alloy hub.

A method of forming a three dimensional object using a low pressure cold spray process for is disclosed. Powdered material is delivered at a temperature below the melting point of the powdered material. A nozzle of a cold spray gun is aligned at an angle θ.sub.1 to the substrate. The powdered material is delivered at a supersonic speed to the substrate causing the powdered material to adhere to the substrate for forming a first layer of material. An amount of optical distortion caused by the first layer of material adhered to the substrate is determined relative to the substrate and the nozzle is reoriented to an angle θ.sub.2 being offset from an axis defined by the first layer of material. A second layer of material is deposited onto the first layer of material with the nozzle being oriented at the angle θ.sub.2 to the first layer of material.
