A method of facing a substrate comprises the steps of first welding a body of a hard facing material to the substrate and then filling a space around the body with a molten metal. The method can be used in the hard facing of metal components with, for example, hard facing materials such as tungsten carbide. The substrate can comprise a metal surface, which can, for example, be the surface of any suitable component, tool, or implement subject to wear in use. The method is particularly suitable for hard facing the wear surfaces of components for use in drill strings in down-hole drilling technology, for example, drill stabilizers. |
