Abstract
A process is disclosed for forming a coating on a substrate. A metal layer is placed onto the substrate either by plasma spray deposition or by applying a metal foil and then subjecting it to rapid omnidirectional compaction. The metal is then reacted with a source of carbon, nitrogen, or a combination thereof, such that a metal carbide, nitride, or carbonitride layer is formed. The product is a densified coated ceramic composition.
