Abstract
A method of forming a downhole tool comprises contacting at least one downhole structure comprising at least one metal material with a molten electrolyte comprising anhydrous sodium tetraborate. Electrical current is applied to at least a portion of the at least one downhole structure to form at least one borided downhole structure comprising at least one metal boride material. Other methods of forming a downhole tool, and a downhole tool are also described.
Claims19
A method of forming a downhole tool, comprising:
- contacting at least a portion of at least one downhole structure comprising at least one metal material with a molten electrolyte comprising anhydrous Na2B4O7;
- and
- applying electrical current to the at least a portion of the at least one downhole structure to form at least one borided downhole structure comprising at least one metal boride material.
A method of forming a downhole tool, comprising:
- at least partially inserting at least one downhole structure comprising at least one metal material into a molten Na2B4O7 at a temperature of from about 770° C. to about 1400° C.;
- applying electrical current to the at least one downhole structure for a period of time within a range of from about one (1) minute to about 5 hours to convert at least a portion of the at least one metal material into at least one metal boride material and form at least one borided downhole structure;
- and
- securing the at least one borided downhole structure to at least one other downhole structure.

A downhole tool, comprising:
- at least one borided structure formed by the method comprising:
- contacting at least a portion of the at least one structure comprising at least one metal material with a molten electrolyte comprising anhydrous Na2B4O7;
- and
- applying electrical current to the at least a portion of the at least one structure in contact with the molten electrolyte to diffuse boron into the at least one structure and form at least one metal boride material.
