Abstract (en)

Metal cast molded body comprises an active surface (2) made from a composite material. The composite material has a porous hard material body (7) in a cast matrix (4) made from metallic cast material. An Independent claim is also included for a process for the production of a metal cast molded body. Preferably the matrix is a wear-resistant iron-based alloy, preferably a wear-resistant cast iron. The hard material body is a ceramic body made from carbides, oxides and/or nitrides, preferably a carbide of Si, Cr, W, Mo, V, Nb, Ti, Zr, Ta or Hf in an amount of 20-70 wt.%. The cast matrix has a bainite and/or martensite structure.
