Claims19
A composite wear part, comprising:
- a ferrous alloy matrix and at least one ceramic reinforcement in the form of an insert having an openwork structure, the openwork structure comprising blind holes;
- wherein blind sides of the holes are positioned on the side of the composite wear part most exposed to wear.
A method for making a wear part comprising a ferrous alloy matrix and at least one ceramic reinforcement in the form of an insert having an openwork structure, the openwork structure comprising blind holes, the method comprising the following steps:
- providing a mold for making a wear part by casting a ferrous alloy;
- placing the insert in the form of an aggregate of millimetric granules of ceramic material or infiltrable ceramic material precursors in the mold, with the blind side on the side of the wear part most exposed to wear;
- and
- causing an infiltration of the insert by the molten ferrous alloy.
