    摘要: Methods for manufacturing a matrix tool body comprising placing a first matrix material within a first region of a mold cavity proximate a surface of the mold. A second matrix material may be placed within a second region of the mold cavity positioned inwardly of the first matrix material. The first matrix material and the second matrix material comprise a plurality of hard particles. The plurality of hard particles of the second matrix material have a median particle size that is less than the median particle size of the first matrix material. The plurality of hard particles of the first matrix material and the second matrix material are infiltrated with an infiltration binder to form the tool body. Also included are tool bodies having one or more regions proximate a surface of the tool body comprising an erosion resistant matrix material and/or a wear resistant matrix material.
