Abstract
A wear-resistant element can be partially inserted into a recess in a surface of a wear area of a comminuting device. The wear-resistant element has a fastening region that can be connected to the recess in the surface of the wear area. The wear-resistant element may also include a wear region that protrudes at least partially from the surface of the wear area. The fastening region may comprise metal. The wear region has a shell and a core arranged inside the shell. The core is comprised of metal, and the shell is comprised of ceramic. The ceramic contains yttrium-stabilized, tetragonal polycrystalline zirconium oxide (TPZ). The TPZ makes up at least 60% by volume of the ceramic in the shell.

A wear-resistant element configured for partial insertion into a recess in a surface of a wear area of a comminuting device, wherein the wear-resistant element comprises:
- a fastening region that is comprised of metal and is configured to be connected to the recess in the surface of the wear area;
- and
- a wear region that protrudes at least partially from the surface of the wear area, with the wear region including a shell and a core disposed inside the shell, wherein the core is comprised of metal and the shell is comprised of a ceramic that contains yttrium-stabilized, tetragonal polycrystalline zirconium oxide (TPZ), wherein the TPZ makes up at least 60% by volume of the ceramic in the shell.
A comminuting device comprising:
- a wear area with a surface that has a recess;
- and
- a wear-resistant element that is attached at least partially in the recess, wherein the wear-resistant element comprises:
- a fastening region that is comprised of metal and is configured to be connected to the recess in the surface of the wear area, and
- a wear region that protrudes at least partially from the surface of the wear area, with the wear region including a shell and a core disposed inside the shell, wherein the core is comprised of metal and the shell is comprised of a ceramic that contains yttrium-stabilized, tetragonal polycrystalline zirconium oxide (TPZ), wherein the TPZ makes up at least 60% by volume of the ceramic in the shell.
