Replaceable hardfacing
A tool can include a substrate with a support surface and at least one mechanical registration feature. The tool can also include a removable wear material including a matrix material. The removable wear material can include a matrix material shaped to be received by the at least one mechanical registration feature of the substrate. The removable wear material can be attached to the substrate so that the at least one mechanical registration feature registers the removable wear material.
1. A tool comprising:
a substrate including a support surface and at least one mechanical registration feature; and
a removable wear surface including a matrix material shaped to be received by the at least one mechanical registration feature of the substrate, wherein the removable wear surface is mechanically attachable to the substrate with a fastener so that the at least one mechanical registration feature registers the removable wear surface, and the removable wear surface is mechanically detachable by removing the fastener from the substrate when the removable wear surface is worn, wherein the fastener is inserted through the substrate from a side opposite the removable wear surface.
2. The tool as recited in claim 1 , wherein the removable wear surface comprises a tungsten carbide matrix material.
3. The tool as recited in claim 1 , wherein the substrate is keyed for registering the removable wear surface.
4. The tool as recited in claim 1 , wherein the removable wear surface is attachable to the substrate using a plurality of fasteners.
5. The tool as recited in claim 1 , further comprising a second removable wear surface to be registered by the substrate, wherein the removable wear surface and the second removable wear surface overlap when registered by the substrate.
6. The tool as recited in claim 1 , wherein the support surface includes a generally cylindrical support surface and the removable wear surface is configured to wear against a mating generally cylindrical surface.
7. The tool as recited in claim 1 , wherein at least one of the substrate or the removable wear surface is secured using a shrink-fit process.
8. A tool comprising:
a substrate including a support surface and at least one mechanical registration feature; and
a removable wear material including matrix material with at least one slot shaped to receive the at least one mechanical registration feature of the substrate, wherein the removable wear material is attached to the substrate so that the at least one mechanical registration feature registers the removable wear material.
9. The tool as recited in claim 8 , wherein the removable wear material comprises a tungsten carbide matrix.
10. The tool as recited in claim 8 , wherein the substrate is keyed for registering the removable wear material.
11. The tool as recited in claim 8 , wherein the removable wear material is attached to the substrate using at least one of a braze, an adhesive, or a fastener.
12. The tool as recited in claim 8 , further comprising a second removable wear material comprising a matrix material registered by the substrate, wherein the removable wear material and the second removable wear material overlap when registered by the substrate.
13. The tool as recited in claim 8 , wherein the support surface includes a generally cylindrical support surface and the removable wear material is to wear against a mating generally cylindrical surface.
14. The tool as recited in claim 8 , wherein at least one of the substrate or the removable wear material is secured using a shrink-fit process.
15. The tool as recited in claim 8 , wherein the removable wear material is molded onto the substrate.
16. A tool comprising:
a substrate including a support surface and at least one mechanical registration feature;
a first removable wear material comprising a matrix material shaped to be received by the at least one mechanical registration feature of the substrate, wherein the first removable wear material is mechanically attachable to the substrate so that the at least one mechanical registration feature registers the first removable wear material, and wherein a mechanical fastener connects the first removable wear material to the substrate from a side opposite the first removable wear surface; and
a second removable wear material comprising a matrix material registered by the substrate, the first removable wear material and the second removable wear material are to overlap when registered by the substrate.
17. The tool as recited in claim 16 , wherein the substrate is keyed for registering the first removable wear material.
18. The tool as recited in claim 16 , wherein the first removable wear material is attachable to the substrate using at least one of a braze, an adhesive, or a fastener.
19. The tool as recited in claim 16 , wherein the support surface includes a generally cylindrical support surface and the first removable wear material and the second removable wear material are to wear against a mating generally cylindrical surface.
20. The tool as recited in claim 16 , wherein at least one of the substrate or the first removable wear material is to be secured using a shrink-fit process.
