Title:
過熱水蒸気脱脂焼結装置
Document Type and Number:
Japanese Patent JP7359459
Kind Code:
B2
Abstract:
To perform a debindering step and a sintering step within a short period of time, and to form a powder-sintered molded body having high precision, in which cracking, splitting and the like hardly occur.SOLUTION: A molding material 13 for sintering comprises a sinterable sintering powder 11 and organic binders 12. The molding material for sintering is used in a method for producing a powder-sintered molded body 14 including: degreasing a sintered material-molded body 10 molded from the molding material for sintering in a predetermined shape, by the action of a superheated steam 6; and performing sintering treatment at predetermined temperature. The molding material for sintering comprises: a first binder component having a disappearing-starting temperature at which the first binder component starts disappearing at predetermined temperature and a disappearing-finishing temperature at which the whole binder component can disappear; and a second binder component that starts disappearing at higher temperature than the disappearing-finishing temperature of the first binder.SELECTED DRAWING: Figure 1
