Shaping the future of lightweight alloy applications

Keronite’s advanced surface treatments are used in thousands of different applications across a diverse set of industries.

Extending Life & Reducing Weight

The premise behind our unique PEO metal coating is simple. It’s the science behind it that’s complex.

Our coatings offer two fundamental benefits:

  1. They extend the life of magnesium, aluminium and titanium components through a range of key characteristics unique to PEO. Our coatings are proven to be far superior to competing coatings such as anodising and thermal sprays.
  2. These improved performance characteristics facilitate the reduction in weight of a component and the wider use of light alloys in multiple industries.

Key characteristics

Keronite produce hard, dense and ceramic coatings for light alloys that can be carefully tailored to provide a combination of different characteristics.

corrosion

Corrosion protection

PEO’s inert ceramic structure provides excellent natural chemical stability and corrosion protection. Coatings have exceeded 2000 hours in salt spray testing (ASTM B117).

wear

Wear resistance

Through a combination of high hardness, strong adhesion and compliance, PEO delivers a complete wear resistant solution for components.

thermal

Thermal Management

We have created coatings for thermal transmission (0.8 – 10 W m-1 k-1) and thermal barrier (up to 900℃) applications. PEO’s versatility enables select thermal management qualities.

hardness

Extreme hardness

PEO delivers up to 2000HV of hardness. PEO coatings are made with phase corundum, one of the world’s hardest natural elements.

electrical

Electrical insulation

Ceramic is a natural insulator, offering impressive dielectric breakdown performance (up to 20kV).

strain

Strain tolerance

PEO’s irregular microstructure and fine-scale porosity adheres superbly to substrates. PEO provides Young’s Modulus values of around 30Gpa.

green

Clean technology

No organic compounds, VoCs, strong acids or heavy metals in sight. Our coatings tick all of the regulatory boxes.

fatigue

Fatigue performance

PEO delivers ultra-precise coatings, with coating thickness starting at just 1μm. PEO’s layer structure and irregular pore structure aids fatigue performance, which means material can be removed to save additional weight.

adhesion

Strong adhesion

Plasma electrolytic oxidation is a conversion process, which means the layer is formed from the substrate, providing exceptional adhesion and excellent coverage.

versatility

Process versatility

Keronite’s scientists can manipulate coatings through tightly controlling PEO processing parameters. Resultant coatings are hugely customisable, which means our scientists can create a coating that hits every goal of your brief.

What is PEO?

Keronite coatings use Plasma Electrolytic Oxidation (PEO) surface treatment technology.

PEO is an electrochemical surface treatment applied to aluminium, magnesium or titanium. Components are exposed to liquid electrolyte and an electrical potential is applied to form an oxide-based ceramic.
