Electrochemical Coatings

Electrochemical coatings is an important field of activity in Materia Nova : from electroplating to anodization Materia Nova develops new coatings and electrolyte formulations for several applications and offers support and services to the industry : plating and characterization facilities for testing and small production, consultancy and troubleshooting

Applications

  • Protection of metals against wear and corrosion
  • Decorative coatings
  • Sensors
  • Black coatings for absorbers

Expertises

  • Formulation of environment-friendly electrolytes for metal plating
  • Formulation of cyanide-free electrolyte for batch and continuous silver electroplating
  • Development of hard chromium coating from trivalent chromium electrolytes
  • Plating facilities : plates (up to A4) and small pieces (barrel) of technical coatings or precious metals
  • Expertise in aluminium anodization : coating parameter optimization, coloration, alternative sealing process (sol gel)
  • Precious metal plating : development and application of post-treatment for increased lifetime with conservation of the aspect.
  • Characterization platform : chemical analysis, morphology and structure, interaction with environment, durability
