摘要： PROBLEM TO BE SOLVED: To solve the problem that frictional parts such as a liner ring of an impeller in a pump and bearings are abraded and eroded by slurry, and further cause pitting corrosion and crevice corrosion after having been used for a long period of time, because the contacting liquid is corrosive like sea water and occasionally contains a solid such as the earth and sand in itself; to provide the frictional parts having both abrasion resistance/erosion resistance and pitting corrosion resistance/crevice corrosion resistance; and to provide an optimum means for adding a desired material on a base material of the component to which the properties are demanded, by a local coating treatment. SOLUTION: An alloy suitable for a padding material with corrosion resistance and abrasion resistance for coating includes Ni, and by wt.% with respect to the total weight, 23-50% Cr, 7-20% V, 1.6% or more but (0.236V%+2)% or less C, Mo in an amount of at most 40% but not less than either (11-0.1xCr %)% or (125-4xCr %)% whichever is greater, and further 90% or less Cr, V and Mo in total.

摘要： PROBLEM TO BE SOLVED: To provide damping material displaying excellent damping performance in a specific temperature area, high in rigidity and suitable for a gasket of an injector fitting part of an automobile engine cylinder head by setting the volumetric occupancy rate of hardened resin material in pores to the specific value or more. SOLUTION: This damping material is composite material with hardened resin material filled in communicating pores of a porous iron group alloy sintered body with the communicating pores, as base material. The porosity of the sintered body is set to 20-50%. In the case of the porosity being less than 20%, rigidity of the damping material is heightened, but the quantity of the hardened resin material filled in the pores is reduced, so that the damping material does not display sufficient damping performance. In the case of the porosity being more than 50%, the mechanical strength of the sintered body itself is lowered, so that damping material with high rigidity cannot be obtained. The hardened resin material is filled in such a way that the volumetric occupancy rate is 40% or more. In the case of being less than 40%, the damping performance of the damping material is lowered.
