Multifunctional coatings formed using organic and inorganic nanomaterials

Abstract

The method of forming composite coatings by the plasma electrolytic oxidation (PEO) using organic and inorganic nanoscale materials is presented. The effect of the incorporated components on the protective properties of the obtained surface layers was studied. It is established that the presence of nanomaterials in the composition of composite coatings makes it possible to reduce the corrosion current density by 4 orders of magnitude in comparison with the base PEO layer. The data of tribological studies confirm a significant increase in the wear resistance of coatings (by 2-4 orders of magnitude). The presence of hydrophobic substances in the composition of composite coatings in combination with the formation technique allows to impart high hydrophobic properties to composite coatings.
