  • Patent number: 10961607
    Abstract: A hardfacing alloy satisfies the following condition when the hardfacing alloy as a whole is 100 mass % (also simply referred to as “%,” hereinafter), Ni: 10-25%, Si: 1-3%, Fe: 3-18%, the total of one or more elements of Mo, W, and Nb: 6.5-20%, and the balance: Cu and impurities. In particular, it preferably satisfies Fe+2Mo?22.6(%), Mo equivalent/Fe?1.17, and Mo equivalent=Mo+0.522W+1.033Nb. In a hardfacing part composed of the hardfacing alloy, coarse hard particles are formed to ensure the wear resistance, and a soft phase present in the hard particles ensures the machinability.

    Abstract: An intermediate member is a member which is directly or indirectly sandwiched between a first object and a second object. The intermediate member includes a plate-like supporting member having a lower surface which is one main surface opposed to the first object and a plurality of ceramic blocks fixed on an upper surface which is the other main surface of the supporting member in a state of being separated from one another. Thus, in a state where the plurality of ceramic blocks are collectively held by the supporting member having relatively high shape retention, by disposing the intermediate member between the objects, it is possible to easily arrange the plurality of ceramic blocks between the objects with high positioning accuracy.
