Abstract
A hardened slip and a method of making the hardened slip are disclosed. A method of hard surfacing a slip component for a downhole tool is disclosed. The slip component may have a bearing surface and may be composed of a base material, the base material being metallic. The method may comprise steps of positioning at least the bearing surface of the slip component with a direct contact with a boron source; bonding an external layer at least on the bearing surface to form a metallurgical bond between boron from the boron source with the base material by boriding the base material; and maintaining a bulk temperature of the slip component below a melting point of the base material.
