Abstract
The present disclosure relates to a wear part made in a foundry. The wear part has a reinforced portion comprising a ferrous alloy reinforced with metal carbides, nitrides, borides, or intermetallic alloys. The reinforced portion includes inserts of metal carbides, nitrides, metal, or intermetallic compounds manufactured beforehand with a defined geometry and inserted into an infiltrable structure of agglomerated grains including the reagents needed for the formation of metal or intermetallic carbides, nitrides, borides according to an in situ self-propagating thermal reaction initiated during the casting of the ferrous alloy.
Claims12
A wear part including:
- a reinforced portioncomprising a ferrous alloy reinforced with metal carbides, nitrides, borides, or intermetallic alloys,
- wherein said reinforced portioncomprises inserts having a predefined geometry,
- said insertscomprising particles of metal carbides, nitrides, borides, or intermetallic compounds prefabricated and embedded in a first metal matrix,
- said insertsbeing inserted into a reinforcement structurealternating areas having a high concentrationof globular particlesof metal carbides, nitrides, borides, or intermetallic alloys with areas being free of the globular particles,
- said ferrous alloy forming a second metal matrix different from said first metal matrix.
