Abstract
Methods for improving adhesion or bonding between materials used in forming components of directional drilling assemblies, such as rotors and stators, are provided. A surface of a component may be treated, such as through cleaning, etching and/or activating a surface. The use of plasma treatment may enhance the adhesion between the surfaces and/or materials to be bonded, thereby reducing the degradation or mechanical failure of these materials in oilfield applications.
