Title:
MANUFACTURING METHOD OF SINTERED BODY, AND SINTERED BODY
Document Type and Number:
Japanese Patent JP2019073759
Kind Code:
A
Abstract:
To provide a manufacturing method of a sintered body capable of stably maintaining a state where green compacts are stacked, when sintering the green compacts.SOLUTION: A manufacturing method of a sintered body includes: a formation step of compression-molding base powder containing metal powder by a metal mold to form a green compact, and form a rough surface region with surface roughness of 5 μm or more at a maximum height Rz at least in part of an end face on one of an upper face and a lower face of the green compact; a stacking step of stacking a plurality of the green compacts so that the end faces have contact with each other; and a sintering step of sintering the plurality of the green compacts in the stacked state.SELECTED DRAWING: Figure 4
