Abstract
A method of forming a valve seat of an engine head formed from a first composition includes forming a groove at a predetermined valve seat location of a bore defined by the engine head. A source of directed heat energy preheats at least the valve seat location to about a temperature of the melting point of the first composition with the source of directed heat energy. The source of directed heat energy is infused with a material having a second composition generating a melt pool upon the groove by direct metal deposition with the melt pool including the second composition. The second composition includes a heat conductivity generally equal to a heat conductivity of the first composition for providing efficient transfer of heat energy from the first composition to the second composition.
