摘要： To provide a corrosion-resisting and wear resisting alloy including cobalt, nickel or iron as a base used for a sliding part or a valve seat for a machine, and restraining erosion and corrosion caused by eutectic carbide constituting the alloy in an atmosphere with dissolved oxygen.
A material is selected from a cobalt base added with Cr and/or W, a nickel base added with Fe and/or Cr, and an iron vase added with Cr and/or Ni. The material is cast into an ingot or a slab to produce an intermediate material. The intermediate material comprises mesh-like eutectic carbide and a base material surrounded by the eutectic carbide. A heat plastic forming is applied to the intermediate material at a temperature 650°C or more and the solidus temperature or less. The eutectic carbide is formed into multiple grains or clusters as a discontinuous distribution. A resulting corrosion-resisting and wear-resisting alloy has 0.1 to 0.5 of coefficient of friction, and 300 to 600 Hv of Vickers hardness without age-hardening process.
