摘要:
A method of protecting an article from a downhole environment comprises growing carbon nanotubes on a surface of a substrate via a chemical vapor deposition process; the carbon nanotubes having a first end formed on the surface of the substrate and a second end extending away from the substrate; filling the spaces among the carbon nanotubes with a metallic material or a polymeric material forming a coated article; and exposing the coated article to a downhole environment.
