A wear-resistant attachment for insertion in a wear-resistant assembly, the assembly comprising a base with at least one recess, the attachment comprising: a bottom part configured to be removably inserted into the recess; and a top part comprising a wear-resistant material, wherein the top part is wider than the bottom part in at least one dimension such that the top part covers a surface of the base beyond the at least one recess. A wear-resistant assembly, comprising: a surface; a base; and a plurality of wear-resistant attachments removably coupled to the base, each of the plurality of wear-resistant attachments comprising an inner portion and an outer portion, wherein the outer portion of each of the plurality of wear-resistant attachments is coupled to the outer portion of at least one other wear-resistant attachment so that a plurality of coupled wear-resistant attachments comprise a substantially continuous surface, the substantially continuous surface comprising at least a portion of the surface of the wear-resistant assembly. A wear-resistant insert comprising a plurality of layers, each layer chosen from the group consisting of a hardface material, a tough material, and a joining interface, wherein the plurality of layers comprises at least two layers of a hardface material. |
