    摘要： The object of the present invention is to provide a valve characterized by excellent corrosion and wear resistance and maintainability by bonding corrosion and wear proof alloy containing non-continuously distributed eutectic carbide to the sliding portions of various types of apparatuses and valves by diffusion bonding. Another object of the present invention is to improve the maintainability of a thermal and nuclear power plant and to provide a nuclear power plant comprising the recirculating water which ensures excellent working safety, in particular.
    A valve and apparatus of a power plant using said valve characterized in that corrosion and wear proof alloy is bonded to the sliding portion, wherein said corrosion and wear proof alloy is further characterized in that network-formed eutectic carbide in the alloy containing the cast structure base metal and eutectic carbide is formed into( multiple) granules or lumps having the particle size of 30 microns or less so that said eutectic carbide is non-continuously distributed.

    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.
