摘要： PROBLEM TO BE SOLVED: To provide a crankshaft manufacturing method that can facilitate light weight of a crankshaft at a low cost and that can satisfy material properties required for the crankshaft along the axial direction.
SOLUTION: This is a method of manufacturing a crankshaft by joining a plurality of joining members to each other. In the method, in joining the joining members 10A, 10B..., those that are sectioned in the faces 30a, 30b...crossing the axial line L of the crankshaft 1 are used as the joining members 10A, 10B.... The joining members are joined by liquid phase diffusion joining by interposing, between the joining members, a low melting point joining material 60 which has a lower melting point than that of the joining members containing a boron element.

摘要： PROBLEM TO BE SOLVED: To provide a stable rust forming method for atmospheric corrosion resisting steel by which stable rust can be easily formed on the surface of the atmospheric corrosion resisting steel. SOLUTION: The stable rust forming method for the atmospheric corrosion resisting steel comprises an oxide film forming step and a stable rust forming step. In this method, the stable rust is formed by allowing a treating solution to react with the atmospheric corrosion resisting steel on which a homogeneous oxide film is formed on the surface. As the result, the stable rust can be easily formed according to this stable rust forming method. COPYRIGHT: (C)2003,JPO
