PlasmaOx Technologies
Smart functional ceramic surfaces for Energy, Water and Advanced Manufacturing.
Corrosion, biofouling and wear silently drain industrial value every year. PlasmaOx provides advanced Plasma Electrolytic Oxidation ceramic coatings that protect critical components across energy, water treatment, aerospace, defence, marine, medical, and industrial sectors.
Substrates We Enhance
PlasmaOx PEO technology transforms the surface of light alloys into high-performance ceramic coatings.
Aluminium
Seawater-exposed pumps, structures and heat-exchange components — protected against pitting corrosion, cavitation and wear by a dense ceramic oxide layer.
Magnesium
The lightest structural metal, including alloys such as AZ91 — given ceramic-grade corrosion and wear protection for demanding energy and mobility applications.
Titanium
High-value titanium components, including additively manufactured parts and novel alloys — enhanced with biocompatible, corrosion-resistant ceramic surfaces.
Performance Beyond Limits
Every PlasmaOx coating is engineered to deliver exceptional mechanical, chemical, and thermal performance.
Corrosion & Biofouling Resistance
Dense ceramic oxide layers resist pitting, seawater corrosion and biofouling in desalination, marine and humid industrial service.
Wear & Cavitation Resistance
Surface hardness of 900–2000 HV protects rotating and high-friction components against wear, erosion and cavitation.
Thermal Stability
Ceramic coatings withstand high temperatures and thermal shock where hard anodising and plasma-spray layers fail.
Dielectric Strength
Dielectric strength of 40–50 kV/mm — well beyond hard anodising — for electrical insulation and high-voltage components.
Complex Geometries & Lightweighting
Grows uniformly on complex shapes and light alloys, enabling aluminium, magnesium and titanium to replace heavier steel.
Eco-Friendly Chemistry
A low-temperature (20–30°C) alkaline process — no aggressive acids, chromates or hazardous heavy metals, and no complex pretreatment.
