ABSTRACT:
A hard facing of preferably a high speed tool steel or a Stellite along the edge of a substrate is produced by mechanical deposition by means of rotary friction surfacing. The combination of high temperatures below the melting points of coating material and substrate and high rates of strain gives rise to a very fine coating microstructure resulting in an edge or valve facing or seat of unexpectedly good mechanical properties and service life.
