PEO Plasma Electrolytic Oxidation

Fakhrandish Aria Co., Considering the modern nature of this knowledge and technology in the world and the high technical status of the PEO process and technique, and the special position of this technique in the modern and advanced industries, as well as the facilities and experiences existing in the company’s field since 2012 about mutual coordination and cooperation With a number of graduates and college students, they have been designing and building the relevant systems and devices, and has so far been able to provide services to some of the organizations and companies that have the technology in the laboratory and industry. Here’s a brief overview of how this system and process work and how it works For any additional information or the need for construction services and consultancy in this field, please contact the engineer’s technical department (Flair and alloys of stainless steel and aluminum alloys And magnesium is still part of the research and work of this collection)

General of the PEO process

The formation of PEO on surfaces involves the formation of a ceramic layer with improved properties of 10 to several hundred microns in thickness. An oxidation coating with polarization at high voltages occurs in a non-corrosive electrolyte, in which electrical sparks are started at a particular voltage and thermal ionization occurs with a cord drain. The oxide layer can melt together with the elements in the electrolyte. PEO can be applied locally to discharge ducts where high pressure and temperature are present. The oxide layer formed above is usually porous, the middle layer is dense and compact, and the bottom layer is also the thinnest layer.

Surface properties due to PEO coating method
  • Creating hard and dense coatings
  • High adhesion to substrates and base metal
  • Resistance to wear and corrosion
  • Creates thermal resistance above the metal surface layer
  • Raise the dielectric coefficient of the material levels
