Abstract

A METHOD OF TREATING A VALVE WITH A COATING (32), SUCH AS TUNGSTEN CARBIDE, INCLUDES DEPOSITING THE COATING WITH A SPRAY STREAM (45) THAT IS ORIENTED PERPENDICULAR TO THE SURFACE BEING TREATED. THE METHOD COMPRISES APPLYING THE COATING OF UNIFORM THICKNESS ONTO LATERAL SURFACE (18) OF A VALVE SEAT (16), A PORTION OF THE VALVE SEAT BORE (22), AND THE CHAMFERED EDGE BETWEEN THE VALVE SEAT LATERAL SURFACE (18) AND THE VALVE SEAT BORE (22). THE VALVE SEAT BORE (22) CAN INCLUDE AN ANNULAR RECESS (55) FORMED TO RECEIVE A LAYER OF COATING.
