摘要：
A method for applying a hardsurfacing material to a workpiece such as a reciprocating aircraft engine tappet in which a carbon-containing wear resistant material in powder form is applied to a surface of the workpiece in the molten state while a sharp temperature gradient is established from the surface into the body of the workpiece to ensure that solidification occurs from the body upward. The resulting surface material consists of wear resistant carbides in a tough martensitic matrix with minimal formation of graphite.
