Title:
JOINED IRON-BASED COMPONENT AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2019056160
Kind Code:
A
Abstract:
To provide a method for manufacturing a joined iron-based component exhibiting a high joining strength.SOLUTION: A method for manufacturing a joined iron-based component in the present invention comprises a fitting step of obtaining an assembly in which, on an outer peripheral side of a first iron-based substance, a close-ringed second compact formed by press-forming a second base powder containing a second iron-based powder is fit, and a sinter-joining step of heating the assembly to obtain a joined iron-based component formed by joining a first iron-based component consisting of a first iron-based substance and a second iron-based component consisting of a second sintered body formed by sintering the second compact at a close-ringed joint interface. The second iron-based powder contains C:0.5-1.8% and a carbide-forming element consisting of W and/or V:6-16% provided that the powder entirety is taken 100 mass%. The second iron-based powder preferably contains further one or more of Si:0.1-1%, Mn:0.1-0.7% or Co:0.1-12%. The base powder may contain a carbon source powder (graphite powder, etc.) meeting C:0.01-0.8 mass%.SELECTED DRAWING: Figure 3A
