Patent ID: 8287966

Claim:
A method of making a vehicle closure panel having joined first and second regions formed of a first material and a second material, where each of the first and second materials may be a metal, metal alloy, or a polymeric composition, the method comprising: spraying atomized droplets of the first material on a spray receiving surface, the spray of the first material being directed to form a sprayed deposit of a first predetermined thickness that is a precursor of the first region of the vehicle closure panel; spraying atomized droplets of the second material on the spray receiving surface, the spray of the second material being directed to form a sprayed deposit of a second predetermined thickness that is a precursor of the second region of the vehicle closure panel, the sprayed first and second materials contacting each other; and subjecting the first and second regions to thermal processing or thermomechanical processing to form the spray deposited precursors of the first and second regions of the vehicle closure panel into the joined first and second regions of the vehicle closure panel.
