TABLE OF CONTENTS Structural inhibited plastics have found application in the sealing of movable and stationary metal-polymer joints operating in hostile environment. They are most efficient in weakly and moderately loaded friction joints, plain bearings and seals. Their main role in metal-polymer friction joints is the reduction or suppression of mechanochemical wear.
Despite the fact that the peculiarities of metal wearing in contact with polymers were determined more than 30 years ago [35]. the serviceability of metal-polymer friction joints has resisted estimates for a long time. The origin of this corrosion wear mode was considered only for plastics processing equipment, in which metals are in contact with the moving polymer melt [36].
In the present chapter we have attempted to generalize the span of phenomena that accompanies friction and defines the mechanochemical behavior of metal wear in conjunction with polymers, and to expound the methods for reducing corrosive wear of metals via imparting the properties of wear inhibitors to polymers. In this regard, wear mechanisms of friction parts in corrosion-active media, corrosion and migration capabilities of plastic components, chemical activity of polymer tribodestruction products and some other factors stimulating corrosion in metal-polymer systems are analyzed. Special attention is paid to the methods of combating wear by electrical fields and potentials arising on metal contact with polymers as well as corrosion inhibitors (CI) impregnated into the polymer or formed during friction.
