Abstract
The present disclosure relates to a hierarchical wear part including a reinforced portion comprising zirconia or an alumina-zirconia alloy. The reinforced portion also includes centimetric inserts with a predefined geometry. The inserts include micrometric particles of metal carbides, nitrides, borides, or intermetallic compounds bonded by a first metal matrix. The inserts are inserted into a reinforcement structure infiltrated by a second metal matrix, the reinforcement structure having a periodic alternation of millimetric areas of high and low concentration of micrometric particles of zirconia or alumina-zirconia alloy. The second metal matrix is different from the first metal matrix.

A hierarchical wear part including:
- a reinforced portion comprising zirconia or an alumina-zirconia alloy, said reinforced portion further comprising centimetric inserts having a predefined geometry,
- said inserts comprising micrometric particles of metal carbides, nitrides, borides, or intermetallic compounds bonded by a first metal matrix,
- said inserts being inserted into a reinforcement structure infiltrated by a second metal matrix, the reinforcement structure comprising a periodic alternation of millimetric areas of higher and lower concentration of micrometric particles of zirconia or alumina-zirconia alloy;
- wherein the second metal matrix is different from the first metal matrix.
