Abstract
A method and apparatus for applying a coating composition to a surface on at least one panel member using a fastener having the composition on its exterior. The fastener, which has a greater coefficient of thermal expansion, is fitted within the panel member, and during thermally-induced expansion, acts to facilitate diffusion of the composition into the panel surface. The coating composition is applied to the fastener via conventional methods to the fastener, and is engineered to react with the material of the panel member to form, via a diffusion process, an intermediate coating in the region of the panel member and coating materials.
Claims7
A method for creating a contamination-preventing seal at a selected surface region of an environmentally-reactive structural component, said method comprising:
- providing a member having a coefficient of expansion greater than the coefficient of expansion of said structural component,
- applying a coating material to the exterior of said member,
- placing said member in contact with said structural component, and
- heating said member to a predetermined temperature such that said member expands into intimate contact with said structural component and said coating material diffuses into the material of said structural component to thereby form a seal at said selected surface region which is environmentally resistant.
