What is Plasma Electrolytic Oxidation?
An innovative, super hard surface coating technology for lightweight alloys
Electrolytic oxidation methods have been prevalent for a long time. Anodising and electroplating based upon the same fundamental chemical principles. Yet it's theses fundamental chemical principles that hold these techniques back.
In modern day, performance-led applications, light alloys must use innovative surface coats. Enhancing performance necessitates a fresh approach to maintain performance.
Plasma Electrolytic Oxidation (PEO) is an innovative bath-based surface coating. Introducing plasma in the formation process circumvents many of the issues with anodising. PEO coatings provide:
- 4x more wear resistance than in hard anodising techniques
- 10x harder coating than 5140 steel
- Superior substrate-coating adhesion
- Suited to corrosion resistant treatments such as sealers, polymers and other topcoats
Plasma Electrolytic Oxidation
Alloys of high Al, Mg and Ti composition can benefit from the superior hardness, wear resistance, and corrosion resistance capabilities of PEO.
