Abstract
A downhole tool for use in wellbores comprises a layer of hydrophobic material over a body, wherein the layer of hydrophobic material comprises a transition metal boride having a higher hydrophobicity than the body. The downhole tool may comprise a body having a composition and the layer of hydrophobic material comprising a discontinuous phase of the transition metal binder dispersed within a first continuous phase comprising a metal binder. The layer of material may be chemically bonded to the body. An interface between the body and the layer of material may comprise the transition metal boride dispersed within a second continuous phase comprising the metal binder and the composition of the body. Methods of forming downhole tools include forming such a layer of material at a surface of a body of a downhole tool.
