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.

Abstract: A thermal spray material feedstock is provided for “flash-carbide” coatings. Flash carbide coatings are thin, dense, and smooth thermal spray coatings that self-activate the substrate. Flash-carbide coatings form and peen the coating to impart compressive stress for good adhesion and corrosion resistance. To achieve this combination of properties and performance, a powder that includes fine, dense, and angular particles is used; however, this powder alone results in a poor deposition efficiency of typically less than 20%. The present disclosure mitigates the poor deposition efficiency of this powder alone by providing a composition having two or more different particles at a specific ratio to improve deposition efficiency with sufficient optimized stress and corrosion properties and, in some cases, an increase in coating performance.
