CERAMIC-METAL COMPOSITE WEAR PART

摘要

The present invention relates to a wear part produced in a foundry with a reinforced part comprising a ferrous alloy reinforced with carbides, nitrides, metal borides or intermetallic alloys for which said reinforced part comprises inserts of carbides, nitrides, metal borides. or intermetallic compounds previously manufactured of defined geometry inserted into an infiltrable structure of agglomerated grains comprising the reagents necessary for the formation of carbides, nitrides, metal or intermetallic borides according to a self-propagating thermal reaction in situ triggered during the casting of the ferrous alloy.
