초록
To replace the high cost material of cobalt matrix, the feasibility of diamond impregnated tools using structure-modified Fenanopowder was investigated in terms of its compaction and related sintering properties. The structure was controlled thatthe spherical agglomerate shape for the easily rearrangement at low pressure range and the bimodal typed porous agglomeratestructure are principally responsible for the green density improvement. The structure modified Fe nanopowder showedhigher compactability than the structure non-treated Fe nanopowder during the compaction process and homogeneouslydispersed diamond in the segment. After sintering, the structure modified Fe nanopowder showed sound segment shape andreached 93.7%T.D. without substantial grain growth. The characteristics of compaction and the sintered segments wereevaluated in terms of the microstructure. Moreover, a prototype product was made and core-drilling test was carried out usingthe structure modified Fe nanopowder. The results are discussed in comparison with the standard of commercial products.
