The invention discloses a
metal injection molding (MIM) high-end cutter,
metal powder and preparation method of the
metal powder. The
metal powder is prepared from the following
raw material elementsin percentage by
mass: 12.0-16.0% of Cr, 2.0-4.0% of Mo, 1.0-4.0% of W, 1.0-3.0% of V, 1.0-1.5% of Cu, 0.5-1.0% of Sn, 0.5-0.7% of Si, 0.5-1.5% of C, 72.0-81.5% of Fe. The
metal powder is prepared through a water-gas combined atomization
powder-preparing mode. The preparation method comprises the technical processes of medium-frequency induction melting of the
alloy elements, water-gas combined atomization,
vacuum drying, powder classification and screening,
batch processing and the like. The prepared
alloy powder has the advantages of uniform
alloy composition, uniform organization structure,
fine powder granularity, reasonable powder distribution, good
sphericity, low
impurity content and the like, and can serve as a
raw material of the MIM high-end tool to be widely applied.
