A composition and process for forming an electrodeposited coating comprising a co-deposit of a metal and MCrAlY particles. The composition includes a metal and a MCrAlY particles, and the electrodeposited coating comprises a metal matrix and MCrAlY particles dispersed in the matrix. In one aspect, a coating is provided that exhibits excellent oxidation resistance and tribological characteristics at high temperatures, including up to at least about 1350&#xb0; F. A high temperature coating may comprise a nickel/cobalt alloy matrix comprising MCrAlY particles and chromium carbide particles dispersed in the nickel/cobalt matrix.

Protective coating for metallic seals

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.
