CERAMIC-METAL COMPOSITE WEAR PART

摘要

The present invention relates to a wear part made by casting with a reinforced part comprising a ferrous alloy reinforced with metal carbides, nitrides, borides or made of intermetallic alloys for which the reinforced part comprises metal carbide, nitride, boride inserts or intermetallic compounds, previously-manufactured, with defined geometry and inserted into a structure that can be infiltrated with agglomerated grains comprising the reagents needed to form metal or intermetallic carbides, nitrides, borides according to a thermal reaction that is auto-propagated in situ, triggered when the ferrous alloy is cast.
