Patent ID: 7306710

Claim:
A method for electroplating a metallic film on a rocket engine combustion chamber component, comprising the steps of: a) providing a tank containing a plating solution and having an immersion depth less than the overall diameter of a combustion chamber component to accommodate only a portion of a surface to be plated on the component, b) rotating the surface of said combustion chamber component ‘off-axis’, such that a central axis of the component is angled with respect to a surface of the plating solution, said surface of the combustion chamber component to be electroplated is approximately parallel to the surface of the plating solution through the plating solution such that only the portion of the surface being plated is immersed within said plating solution at any time while being rotated; and, c) applying a current to an anode positioned in said tank proximate the surface of the combustion chamber component to be electroplated, wherein when said combustion chamber component is rotated, the immersed portion of the surface is deposited with metal from the plating solution.
