    摘要: In a part for a rotary machine, a ceramic hard film is formed on a surface of a base material, the density of droplets which exist in a surface of the ceramic hard film is set to be within 1000 pieces/mm2, and the density of droplets whose mean particle diameter is 1 μm or less is set to be within 550 pieces/mm2. A method for manufacturing the part of a rotary machine is a method for forming the ceramic hard film by at least an ion plating method or a sputtering method.

    摘要: A solid particle erosion resistant surface treated coat is provided by which a solid, particle erosion resistance is largely enhanced and a rotating member is given with an oxidation resistance without deteriorating a fatigue strength. Also, a rotating machine, such as a steam turbine, axial compressor or the like, applied with this coat is provided. The solid particle erosion resistant surface treated coat comprises a nitrided hard layer formed on a surface of base material and a PVD (physical vapor deposition) hard layer of at least one layer formed on the nitrided hard layer by a PVD method. The nitrided hard layer has a thickness of at least 30 μm. The PVD hard layer has a total thickness of at least 10 μm. Deformation of the base material by collisions by solid particles is prevented and crack of the coat comprising the nitrided hard layer formed on the base material and the PVD hard layer formed on the nitrided hard layer is prevented. Thereby, the solid particle erosion resistance is secured, life of the solid particle erosion resistant surface treated coat can be elongated and the oxidation resistance and fatigue strength are enhanced.

    摘要: A hub is supported rotatably about an axis of rotation, and the diameter thereof increases from upstream to downstream sides along a fluid flow. A plurality of impeller blades extend radially outward from an outer circumferential surface of the hub. A shroud is formed in a cylindrical shape whose diameter increases from the upstream to downstream sides along the fluid flow and joins outer circumferential ends of the plurality of impeller blades. The impeller blades are composed of upstream blade segments and downstream blade segments bonded at a bonding surface extending in a direction substantially perpendicular to the axis of rotation. The upstream blade segments are integral with at least a portion of the shroud, and the downstream blade segments are integral with at least a portion of the hub. This improves the reliability and performance of an impeller and a compressor.

    摘要: An object is to provide a gas-compressor impeller which has excellent durability even when gas containing solid particles is compressed and which does not increase the cost. A gas-compressor impeller installed in a gas compressor that compresses gas containing solid particles has a hub portion and a plurality of blades extending substantially radially from the outer circumferential surface of the hub portion. The hub portion and the blades are rotated about the central axial line to compress gas. The blades have abrasion-resistant films only at gas inlet portions.
