Abstract
A valve seat ( ) is formed by build-up cladding by irradiating a laser beam on a copper alloy powder ( ) provided in the rim of a port ( ) formed in an engine cylinder head ( ). The copper alloy powder ( ) consists of copper (Cu), 6-9 wt % nickel (Ni), 1-5 wt % silicon (Si), and 1-5 wt % of one of molybdenum (Mo), tungsten (W), tantalum (Ta), niobium (Nb) and vanadium (V). Due to this composition, the valve seat ( ) has few microcracks and excellent abrasion resistance.
