Liquid phase diffusion welded metal-made precision machine component and production method thereof |
摘要 |
A precision machine part is made of a plurality of pieces with a transient liquid phase diffusion bonding alloy provided between the pieces to bond them together. The precision machine part has one or more conveyance passages formed in it, has a longitudinal axis and is configured to permit passage of liquid or gas through the conveyance passage from a pipe line or cylinder. The pieces of the precision machine part are adhered to each other by transient liquid phase bonding with a ribbon of an amorphous bonding alloy. The bonding alloy can contain 1 to 10 atomic % V or can contain 1 to 15 atomic % of B or P or a mixture of B and P and 1 to 10 atomic % V, the balance being Fe and unavoidable impurities, and can exhibit an amount of contraction in a bonding stress loading direction caused by plastic deformation in the bonding process of not more than 5%. The bonding alloy may be an amorphous Ni-based alloy.
