METHOD OF FABRICATING NANO METAL SINTERED PART BY REDUCTION-SINTERING HYBRID PROCESS

摘要

A nano-metal sintering method through a reduction-sintering integrated process is provided to enable the manufacture of the molding product in which the powder packing factor is high even at low pressure and pressure-less condition. A nano-metal sintering method through a reduction-sintering integrated process is as follows. The molding product is manufactured using nano-sized metal oxide powder(S2). In the reducing atmosphere, reduction and sintering of the molding product are performed(S3) at the same time and the nano metal sintered product is manufactured. The nano-sized metal oxide powder is pulverized and prepared by the ball milling method or circulation bead milling method.
