A method of coating an internal surface of a tubular member includes: forming a sublayer on the internal surface of the tubular member, the sublayer including a chromium sublayer, a polymer sublayer containing electrically conductive or semi-conductive particles, or a diamond-like carbon sublayer containing an undoped diamond-like carbon material; disposing a hydrophobic layer on the sublayer via a plasma-assisted chemical deposition thereby forming the coating on the internal surface of the tubular member, the hydrophobic layer including a doped diamond-like carbon material, and the doped diamond-like carbon material containing an amorphous diamond-like carbon doped with Si and optionally at least one of F, Co, Cr, W, or Ti.

Methods for producing layered nanocarbon structures placing a workpiece in a working chamber, applying a vacuum to the chamber, processing the workpiece surface with gas ions, applying a material sublayer to the workpiece surface, depositing carbon ions from a carbon plasma on the workpiece surface to apply an amorphous diamond-like sp3 carbon coating layer on the workpiece surface. The methods include irradiating the growing carbon coating with accelerated ions of an inert gas at a first energy range to apply a graphite sp2 carbon coating layer on the sp3 carbon coating layer and irradiating the growing carbon coating with accelerated ions of the inert gas at a second energy range, different from the first energy range, to apply a linear chain and polymer sp1 carbon coating layer on the sp2 carbon coating layer.
