Use of Aluminium Grows As Surfaces Get Harder
01 Sep 2003
The limiting factor in the use of aluminium has always been the soft surface and tendency to wear. Abbey Metal Finishing (Amfin) of Nuneaton believes that they have found the solution in their recent installation of a Keronite surface treatment facility.
Around 30% of all aluminium production is used by the car industry, the European Aluminium Association expects the average vehicle to contain 200kg of aluminium by the year 2015.
Independent tests have shown that Keronite coatings are three times harder than hard anodising, more wear resistant and far less prone to cracking.
The outer surface is more porous and lends itself well to the application of decorative top coats. When impregnated with PTFE, wear resistance can be improved even further.
This revolutionary technology was developed by Keronite Ltd of Cambridge. The process uses plasma electrolytic oxidation to transform the surface of the substrate alloy into a hard, dense layer of ceramic (alumina) which not only has excellent wear resistance, but also improved protection against corrosion.
