In case of using titanium alloys in equipment exposed to aggressive media (for example, sea water), it is necessary to take into account and, first of all, prevent the formation of a galvanic couple of titanium and another metal/alloy, which in most cases leads to the corrosion destruction of the latter. Another significant problem of using titanium is its low wear-resistance and poor tribological characteristics. To impart the necessary properties to titanium and its alloys, a composite coating was formed on the top of titanium. For the coating formation, a combination of the plasma electrolytic treatment and polymer spraying was used. The SEM, EDS and XRD analyses established morphological features, elemental and phase composition of the composite coatings. Contact angles and the wettability parameters of the composite coatings were investigated. An analysis of the data obtained showed that composite coatings have better protective properties than untreated material and base PEO coatings.
