In-situ surface treatment containment apparatus and method
First Claim
1. The method of providing a containment for treating a surface in-situ, comprising:
- attaching a moldable, sealing material to said surface;
attaching a treating membrane to said moldable sealing material to form a treating chamber, said treating chamber including a conductive screen and an insulating member disposed between said conductive screen and said surface;
creating a vacuum within said treating chamber; and
providing a fluid within said treating chamber, said vacuum causing said fluid to be distributed between said conductive screen and said surface.

Abstract
A method and apparatus for a containment for treating a surface, such as on an aircraft, in-situ. A treating compartment having a conductive screen and an insulating fiber member therein is held in place on the surface by a retaining membrane attached around the periphery of the treating compartment. The treating fluid is held in a separate container that is coupled to the treating compartment. A suction is placed on the treating compartment which pulls the membrane, screen and fiber against the surface and into contact with each other. The suction also pulls the treating fluid into the treating compartment. The fluid spreads evenly along the insulating member disposed between the screen and the surface under treatment. A voltage potential difference is placed between the conductive screen and the surface, causing current to run through the treating fluid to provide treatment of the surface. After the treatment is completed, the suction from the treating compartment is removed and the fluid returned to its container. The retaining membrane is removed and the entire apparatus removed from the surface.

4. The method of treating a surface in-situ, comprising:
-
coupling a retaining membrane to said surface with an airtight seal to create a retaining chamber; coupling a treating membrane to said surface with an airtight seal to create a treating chamber, said treating chamber being surrounded at said surface by said retaining chamber, said treating chamber including a conductive screen and a fiber member disposed between said conductive screen and said surface; removing air from said retaining membrane to create a suction force for retaining said treating membrane on said surface; coupling a treating fluid to said treating chamber; removing air from said treating chamber to create a suction force acting to draw said treating membrane toward said surface and also acting to draw said fluid into said treating chamber; placing a voltage on said screen to create a voltage potential between said screen and said surface, causing current to flow through said treating fluid; removing said voltage from said screen; returning air to said treating chamber; and returning air to said retaining chamber.

10. The method of treating a surface in-situ comprising:
-
coupling a treating membrane to said surface to be treated with an airtight seal to create a treating chamber, said treating chamber including a conductive screen and a fiber member disposed between said conductive screen and said surface; coupling a source of treating fluid to said treating chamber; creating a vacuum in said treating chamber to provide a suction force for drawing said treating fluid into said fiber member, said treating fluid being disposed between said conductive screen and said surface; placing a voltage on said screen to create a voltage potential between said screen and said surface for causing current to flow through said treating fluid; removing said voltage from said screen; and releasing the vacuum on said treating chamber. - View Dependent Claims (11, 12, 13, 14)
