Process lines for applying porous, inorganic, and non-metallic nanostructured coatings to aluminum, magnesium, titanium, and zirconium surfaces

Processing lines for applying inorganic, nonmetallic ceramic coatings to metal surfaces will be the main product of this project. The technology was developed by a group led by Professor Anatoly Mamaev, doctor of chemistry.

Micro-arc oxidation technology provides resistance to wear (two to eight times greater resistance), corrosion, and heat and improves the decorative properties of aluminum, magnesium, titanium, and zirconium components. This opens new uses for the metals and reduces production costs. The technology is safer for the environment because it is less likely to explode and produces no cyanide or nickel/chrome waste.

Areas of application

  • Construction
  • Automotive industry
  • Machine building

Competitive advantages

  • Environmentally clean technological process
  • Low energy consumption
  • Broad spectrum of functional applications

This method of micro-arc oxidation was developed in Russia in the late 1980’s. Due to high energy consumption, the cost of MAO coating was higher than traditional methods, preventing its adoption. The research team for the project overcame the major obstacle to MAO by using advanced power sources, and that made the method cost effective.

Device for micro-arc oxidation
Porous ceramic coating is formed on the surface of valve metals: Al, Mg, Ti, Ta, Nb, Zr, Be, or their alloys.
