Abstract:
Embodiments of the present technology may include a method of improving tribological and corrosion properties of an oilfield tubular for conveying hydrocarbons. The method may include depositing a first layer comprising aluminum over a substrate. The substrate may include a ferrous alloy. The method may also include immersing the substrate and the first layer in an alkaline electrolytic liquid bath. The method may further include oxidizing a first portion of the first layer by micro arc oxidation to form a second layer over a second portion of the first layer. The second layer may include aluminum oxide. The oilfield tubular may include the substrate, the first layer, and the second layer.
