  • Surface treated product, surface treatment method, and surface treatment apparatus
    Patent number: 7458881
    Abstract: There is provided a surface treated product that moves relatively in a fluid, wherein a surface of the surface treated product has continuous dimples, each dimple having a diameter of 10 to 2500 ?m and a depth of 50 ?m or less. The surface treated product significantly reduces resistance of a fluid to an object in the fluid, and significantly improves a flow state of the fluid.
    Type: Grant

  • Hollow casting and manufacturing method therefor, and method and apparatus for smoothing internal surface of hollow casting
    Publication number: 20040000384
    Abstract: There is provided a hollow casting in which a surface roughness Ra of a casting wall portion surface forming a hollow portion formed by a wall portion is 10 &mgr;m or less. Such a hollow casting can be obtained by a manufacturing method for the hollow casting in which after molten metal is poured into a mold to be molded by casting, processing of removing residual matters on the casting wall portion surface forming the hollow portion and processing of smoothing the casting wall portion surface forming the hollow portion are performed at the same time under predetermined conditions. According to the present invention, a casting which has the hollow portion formed by the wall portion and whose wall portion surface forming the hollow portion is very smooth and which has a low passage resistance can be manufactured at a lower cost without increasing an environmental load in the manufacturing process.
