PROCESS FOR PRODUCING PRECISION METAL PARTS BY POWDER MOULDING |
摘要 |
A process for producing a precision metal part of a sintered body by the powder molding using a metal powder of which the oxygen content and the hydrogen reduction loss are controlled to 0.5-6 wt. % and 1-7 wt. %, respectively. The sintered body has a high density near the true density and is excellent in dimensional accuracy. The molding is facilitated, and the process is simple. <IMAGE> |
