1. A method of coating an alloy wheel, comprising the steps of:
forming a wheel including an alloy substrate having a three dimensional configuration defining a face and recessed surfaces;
applying a base polymer coating over said alloy substrate;
machining said face of said alloy substrate thereby removing said base polymer coating and re-exposing the alloy substrate for providing a smooth surface at said face and defining an edge between said smooth surface of said face and said recessed surfaces with said recessed surfaces retaining said base polymer coating;
providing a nozzle element for projecting an atmospheric plasma jet toward said wheel;
after machining said face of said wheel, projecting the atmospheric plasma jet from said nozzle element toward said smooth surface of said face, said edge, and toward at least a portion of said recessed surfaces thereby forming an alloy oxide of said alloy substrate at least on said face and said edge disposed between said face and said recessed surfaces;
applying a second polymeric coating over said face, said recessed surfaces and said edge disposed between said face and said recessed surfaces, thereby adhering said second polymeric coating over said alloy oxide.
