A process for the manufacture of a metallic seal comprising applying a first intermediate layer to a base metal, applying a second intermediate layer overlying the first intermediate layer, applying a first coating layer comprising silver overlying the second intermediate layer, applying a second coating layer comprising indium overlying the first coating layer, baking the base metal with applied intermediate and coating layers at a temperature to diffuse the coating layers to form a silver indium alloy coating layer. A seal comprising a substrate having a metal surface, a first intermediate layer overlying the base metal, a second intermediate layer overlying the first intermediate layer, an alloy coating layer overlying the second intermediate layer, wherein the alloy coating layer comprises a silver indium alloy.

Process for coating silver indium alloy metallic seal

A seal assembly () for sealing first and second static parts (A,B) with opposed slots (A,B) together forming a pocket (). The seal assembly () comprises a floor strip () positioned adjacent the pocket's floor () and a ceiling strip () positioned adjacent the pocket's ceiling (). A connection () of the strips' central portions () provides a flat hinge between cooperating hinge portions (). A first set of the hinge portions (A-A) converge for insertion into the first slot (A) and a second set of hinge portions (B-B) converge for insertion into the second slot (B). After such slot insertion and pocket installation, the converged hinge portions (A-A,B-B) resiliently diverge within the pocket to seat the floor strip's end portions (A,B) against the pocket's floor () and to seat the ceiling strip's end portions (A,B) against the pocket's ceiling ().
