Surface & Multifunctional Coatings Technologies Platform

This equipment is dedicated to the development of new coatings on metallic alloys by the use of an innovative process called Micro-Arcs Oxidation (MAO) or Plasma Electrolytic Oxidation (PEO).
It enables to study and optimise the many key process parameters and also to develop new technological solutions.
