Plastics for corrosion inhibition

Abstract

The development of polymer composites containing inhibitors of metal corrosion is an important endeavor in modern materials science and technology. Corrosion inhibitors can be located in a polymer matrix in the solid, liquid, or gaseous phase. This book details the thermodynamic principles for selecting these components, their compatibility, and their effectiveness. The various mechanisms of metal protection – barrier, inhibiting and electromechanical – are considered, as are the conflicting requirements placed on the structure of the combined material. Two main classes of inhibited materials (structural and films/coatings) are described in detail. Examples are given of structural plastics used in friction units subjected to mechano-chemical wear and of polymer films/coatings for protecting metal objects against corrosion.
