Abstract
A hardfacing apparatus includes a deposition head including a heat source, a hardfacing material source, and a chill block having a chill block surface. The deposition head is positioned at a location so as to deposit a mass of the hardfacing material onto the workpiece surface. The chill block is positioned remote from the deposition head with the chill block surface in a facing-but-spaced-apart relation to the workpiece surface, separated from the workpiece surface by a gap having a dimension between the chill block and the workpiece surface of a standoff distance D.sub.S. Molten hardfacing material is deposited onto the workpiece surface from the deposition head. Simultaneously, the workpiece surface is moved relative to the hardfacing apparatus so that the molten hardfacing material passes into the gap and is molten as it enters the gap.
