Our Method of Plasma–Electrolytic Oxidation

Plasma–Electrolytic Deposition or Oxidation is the formation of inorganic surface structures on the materials, conducting current (mainly metals and alloys) from electrolytes by the use of electric discharges (spark (а), arc (в)).

Discharge evolution during the layer thickness increasing.

Processes taken place in the discharge channels region (at average solution temperature below 100^оС):

• Initiation of phase transformations in the oxide film;
• Thermolysis of the adsorbed compounds and deposit from electrolytes;
• High-temperature solid-state interactions and interactions in melts;
• Hydrothermal synthesis reactions.

The main advantages of the method:

1. Comparative simplicity, technology.
2. Possibility to form the layers of different structure and purposes.
3. Possibility to work the constructions of complex forms, with welded and riveting joints, from heterogeneous alloys up.
