Tel:+34 943 206 744

TEKNIKER's infrastructure is dedicated to the development of multifunctional ceramic coatings using Plasma Electrolytic Oxidation (PEO) on lightweight Al, Mg and Ti alloys.

PEO technology produces high-hardness coatings with excellent corrosion and wear resistance directly on the material surface through plasma discharges in an electrolytic solution. The infrastructure is equipped with AC and pulsed bipolar power supplies and processing cells with capacities of up to 150 L.

Equipment

• PEO system with AC power supply and 3 L and 50 L processing cells
• PEO system with pulsed bipolar power supply (HiPIMS) and 5 L, 50 L and 150 L processing cells
• Auxiliary equipment for electrolyte temperature control, agitation and filtration
• Instrumentation for real-time process monitoring and control

• Development of multifunctional ceramic PEO coatings on Al, Mg and Ti alloys
• Improvement of corrosion and wear resistance, as well as the dielectric properties of lightweight alloys
• Optimisation of PEO process parameters (electrolyte, electrical regime, temperature and processing time)
• Adaptation to different component geometries and sizes
• Process scale-up from laboratory to pilot production
• Characterisation of PEO coatings (thickness, hardness, porosity and composition)
