A centrifuge conveyor is provided with improved hard surfacing wherein unitary subassemblies of backing tiles and wear-resistant members are welded by the backing tile to the conveyor. A subassembly is made unitary by the interengagement of the wear-resistant member to an undercut groove in the backing tile and by bonding with a heat reactive adhesive or grout applied to the interengaging parts. Each fragile wear-resistant member is braced against deflection at its outer portion through its backing tile to the conveyor. The preferred embodiment employs a plurality of wear-resistant members per backing tile, each such member being accurately pressed to its intricate, interlocking shape from sintered tungsten carbide. |
