  • Patent number: 7811511
    Abstract: Hard phase particles including Co alloy particles, carbide alloy particles, and silicide particles are dispersed substantially uniformly throughout a matrix composed of Cu self-fluxing alloy of a cladded portion. The cladded portion contains 6 to 15% by weight of Co, 3 to 8% by weight of one of Cr and Mo, 0.3 to 1% by weight of W, 0.5 to 1.8% by weight of Fe, 8 to 15% by weight of Ni, 0.08 to 0.2% by weight of C, 1.5 to 4% by weight of Si, 0.5 to 0.8% by weight of Al, and 0.1 to 0.3% by weight of P, and inevitable impurities and Cu as a balance. The hard phase particles have an average particle diameter of 8 to 20 ?m and a particle size distribution width of 0.1 to 100 ?m, and to occupy 10 to 20% in an arbitrary cross section of the cladded portion.

  • Patent number: 7757396
    Abstract: There are disclosed a laser clad valve seat raw-material powder superior in productivity, cladding property, wear resistance and finishing property, and a laser clad valve seat using the same superior in wear resistance. The row-material powder comprises a powder mixture comprising: 80 to 99% by weight of a Cu-based alloy powder comprising 0.5 to 5% by weight of B, 0 to 20% by weight of Ni, 0 to 10% by weight of Fe plus Co, 0 to 5% by weight of Si, 0 to 3% by weight of Al, and the balance Cu and unavoidable impurities; and 1-20% by weight of an Fe or Co based alloy powder having a Vickers hardness of 500 HV or higher and an average particle diameter of 50 to 200 ?m of and comprising 5 to 40% by weight of Mo, 0 to 25% by weight of Cr, 0 to 5% by weight of Si, and the balance Fe or Co and unavoidable impurities.
