Formation of Manganese-Containing
PEO Coatings on Aluminum Alloys
Hanna Karakurkchi, Maryna Ved’, and N. D. Sakhnenko
Increasing the complexity, accuracy, reliability, and versatility of technical devices
and their elements requires the widespread use of functional coatings for various
purposes. The development of eco-friendly novel and original technologies for the
producing of coatings with a wide range of functional properties on metal carriers
is today one of the urgent tasks [1, 2]. This is due to the toughening of operating
conditions and aggressiveness of the applied technological environments, as well as
a general increase in the requirements for the used structural materials. Plasma electrolytic oxidizing (PEO) provides coatings similar to ceramic [3]. Such systems have
a unique complex of properties, in particular catalytic, wear-, heat- and corrosionresistant, and electrical insulating [4, 5]. A PEO feature is the possibilities of implementing in one process both material surface treatment procedure and the synthesis
of oxide coatings. Obtained oxide layer may include metals from the processing
substrate as well as the electrolyte components derivatives, and the resulting coatings
are significantly greater in thickness than traditional oxide films [6].
Aluminum and alloys based on it are widely applied as construction materials and
carriers of various active systems. This is facilitated by the features of their physicmechanical and chemical properties. The presence of intermetallic compounds with
magnesium, manganese, iron, and copper in the alloys provides a combination of
mechanical strength and lightness of products. At the same time, surface heterogeneity significantly reduces corrosion resistance in aggressive environments and
complicates the PEO process. It is especially difficult to synthesize thick coatings
on copper-containing aluminum alloys [7].
Formation of coatings with mixed oxides on multi-component aluminum alloys,
in most cases, is carried out by impregnation pre-oxidized porous layer of substrate
