Abstract
A method of manufacturing a two piece metal housing having wear resistant interior surfaces is disclosed. The method includes the steps of: machining, by wire electrical discharge machining, a slightly oversized shape into an assembled two piece, split metal housing; disassembling the two piece, split metal housing; applying a hard material to the inner surfaces of the machined area of each of the two pieces with a hard material; after completion of the material applying step, reassembling the two pieces of the split metal housing; and machining the interior surfaces of the surfaces of the area where the hard material was applied to the reassembled metal housing by wire electrical discharge machining to predetermined dimensions. The wear resistant material is preferably a ceramic material, tungsten carbide, or a high velocity oxy-fuel (HVOF) applied hard-coating or other conventional material usable in the specific application.
