Coating system for tubular gripping components

1. A gripping tool, comprising:

a gripping element;

a plurality of teeth extending from the gripping element;

an outermost layer extending a depth from an outer surface of the gripping element, wherein the outermost layer is boronized; and

a carburized layer extending from the outermost layer to a base material of the gripping element, wherein the carburized layer comprises a carbon content greater than the base material.

2. The gripping tool of claim 1 , wherein the boronized outermost layer has a maximum hardness ranging from about 900 HV to about 2200.

3. The gripping tool of claim 1 , wherein the carburized layer has a maximum hardness ranging from about 50 HRC to about 65 HRC or about 510 HV to about 830 HV.

4. A gripping tool comprising:

a gripping element;

at least one gripping surface formed on the gripping element, wherein the at least one gripping surface comprises:

a plurality of teeth extending from the gripping element; and

an outermost layer extending a depth from an outer surface of the gripping element,

at least one inner layer formed between the outermost layer and a base substrate material, wherein the inner layer is formed by an elemental diffusion process and the outermost layer is formed by a separate elemental diffusion process.

5. The gripping tool of claim 4 , wherein the outermost and/or inner layer is created by an elemental diffusion of one or more elements selected from a group consisting of cobalt, tungsten, molybdenum, titanium, nickel, and copper.

6. A The gripping tool of claim 4 , wherein the outermost layer is created by the diffusion of carbon, nitrogen, boron, aluminum, silicon, chromium, titanium, or vanadium, alone or in combination.

7. A gripping tool, comprising:

a gripping element;

at least one gripping surface formed on the gripping element, wherein the gripping surface is formed by an additive manufacturing process.

8. The gripping tool of claim 7 , wherein a base material has a diffusion layer added prior to the gripping surface being added by the additive manufacturing process.

9. The gripping tool of claim 7 , wherein a material added by the additive manufacturing process is non-ferrous.

10. The gripping tool of claim 7 , wherein at least one gripping surface comprises a plurality of teeth formed by the additive manufacturing process.

11. The gripping tool of claim 10 , wherein a base material has a diffusion layer added prior to the gripping surface being added by the additive manufacturing process.

12. The gripping tool of claim 10 , further comprising adding an outer layer to the plurality of teeth.

13. The gripping tool of claim 12 , wherein the outer layer is a diffusion layer.

14. The gripping tool of claim 7 , wherein at least one gripping surface comprises a plurality of teeth formed by a material removal process.

15. The gripping tool of claim 14 , further comprising an outer layer is added to the plurality of teeth.

16. The gripping tool of claim 15 , wherein the outer layer is a diffusion layer.

17. A gripping tool, comprising:

a gripping element;

wherein the gripping element has a hardness greater than a hardness of a tubular pipe;

wherein the gripping element is formed by an additive manufacturing process;

wherein the gripping element is configured to provide rotational and axial gripping force to the tubular pipe; and

wherein the gripping element is configured to reduce or prevent the transfer of residual free iron to the tubular pipe.

18. A method of manufacturing a gripping tool, comprising:

carburizing a gripping surface formed on a gripping element of the gripping tool; and

forming an outer layer;

wherein the outer layer comprises:

a boronizing layer extending a depth from an outermost surface of the gripping element; and

a carburized layer extending from the boronized layer to a base material of the gripping element.
