Technological process and equipment for plasma electrolytic oxidation (PEO)


The equipment allows to produce wear- and corrosion-resistant oxide ceramic coatings of the thickness up to 200 mkm and hardness up to 20 GPa on parts and elements of structures.

The equipment is connected to the three–phase network with a power of 380 V and a frequency of 50 Hz and provides a separate voltage control on the positive and negative semi-waves.

Innovative Aspect and Main Advantages

  • the equipment allows to treat details of different size and shape, in this case all surfaces are treated uniformly and qualitatively;
  • the method is simple and doesn’t require highly-skilled staff.

Areas of Application

  • engineering;
  • aerospace industry
