Powdertech Surface Science has been the exclusive UK production partner of Keronite® for over ten years. In this time we have collaborated with the Keronite® technical team on coating various aluminium and magnesium alloys, installed Keronite® plant/equipment at our premises and used our expertise to manage many projects from initial concept through to production.
Powdertech has the largest fully automatic Keronite® line in the world, which is currently used to process premium aluminium wheels for the cycle industry.
The patented Keronite® process uses Plasma Electrolytic Oxidation (PEO) to transform the surface of light alloy aluminium and magnesium into a dense, hard ceramic with outstanding resistance to corrosion and wear.
The thin outer layer of the Keronite® ceramic surface is an ideal base for the application of powder top-coats. As Keronite® is anatomically bonded to the substrate alloy, the Keronite® ceramic layer has adhesion properties similar to the fracture strength of the alloy itself, reducing the risk of delamination of the coating.
Keronite® as a ceramic is inert to most chemicals/corrosive environments and performs extremely well in preventing corrosion of both aluminium and magnesium.
