Structure and Tribological Properties of Polytetrafluoroethylene Nanocomposite Coatings Formed from Active Gas Phase
Keywords:nanocomposite coating, morphology, attenuated total reflection, tribological properties.
Surface morphology and structure of micro- and nanocomposite polymer-polymer (polytetrafluoroethylene and
polyurethane) and metal-polymer (polytetrafluoroethylene and copper or iron) coatings obtained by vacuum plasma
method were investigated. The influence of coating composition and deposition conditions onto coating properties and
structure were analyzed. The peculiarities of deposition of nanocomposite polymer-polymer and metallopolymer
coatings structure and properties of formed surface layers were determined. It was shown that the polymer-polymer
coating presents a fine-grained micro- and nanocomposite binary mechanical mixture of the modified components.
Additional activation of the dispersion products leads to the formation polymer-polymer and metal-polymer coatings
with excellent tribological properties.
