摘要：

The earlier developed approaches to the formation of composite polymer-containing coatings by plasma electrolytic oxidation (PEO) using various low-molecular fractions of superdispersed polytetrafluoroethylene (SPTFE) have been summarized. A unique method for the formation of a composite polymer-containing coating at the surface of magnesium alloy MA8 has been suggested. The improvement in the corrosion and tribological behavior of the polymer-containing coating can be attributed to the morphology and insulating properties of surface layers and solid lubrication effect of SPTFE particles. Such multifunctional coatings have high corrosion resistance (R-p = 3.0 x 10(7) Omega cm(2)) and low friction coefficient (0.04) under dry wear conditions. (C) 2014 Elsevier Ltd.
