Abrasion resistant copper alloy, copper alloy powder for build-up cladding, and engine cylinder head |
摘要 |
A valve seat (2) is formed by build-up cladding by irradiating a laser beam on a copper alloy powder (4) provided in the rim of a port (3) formed in an engine cylinder head (1). The copper alloy powder (4) 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 (2) has few microcracks and excellent abrasion resistance.
