<p>A sintered seal having metallic fibers, at least one lubricant, and a powdered alloy having a relatively lower melting point than the metallic fibers. The seal is sintered in a reducing atmosphere to convert chromium, boron, and carbon compounds in the alloy to borides and carbides which form a coating over the metallic fibers and evenly distributed sites of wear resistant carbides and borides.</p> |
