초록
This paper reviews recent approaches to develop composite polymer-containing coatings by plasma electrolyticoxidation (PEO) using various low-molecular fractions of superdispersed polytetrafluoroethylene (SPTFE). The features of the unique approaches to form the composite polymer-containing coating on the surfaceof MA8 magnesium alloy were summarized. Improvement in the corrosion and tribological behavior ofthe polymer-containing coating can be attributed to the morphology and insulating properties of the surfacelayers and solid lubrication effect of the SPTFE particles. Such multifunctional coatings have high corrosionresistance (Rp = 3.0×107 Ω cm2) and low friction coefficient (0.13) under dry wear conditions. The effectof dispersity and x-potential of the nanoscale materials (ZrO2 and SiO2) used as electrolyte componentsfor the plasma electrolytic oxidation on the composition and properties of the coatings was investigated. Improvement in the protective properties of the coatings with the incorporated nanoparticles was explainedby the greater thickness of the protective layer, relatively low porosity, and the presence of narrow non-throughpores. The impedance modulus measured at low frequency for the zirconia-containing layer (|Z|f=0.01 Hz =1.8×106 Ω·cm2) was more than one order of magnitude higher than that of the PEO-coating formed inthe nanoparticles-free electrolyte (|Z|f=0.01 Hz = 5.4×104 Ω·cm2).
