polymeroxid® LF4®
but low friction!
Born for racing
Our polymeroxid®–LF4 process is a new anodic special coating for applications in which surface smoothness is paramount. With a slightly reduced hardness compared to xH4®, the friction properties have been further optimized. When using suitable materials, an excellent decorative effect can be achieved, opening up new possibilities for which hard anodizing was previously not suitable.
polymeroxid®–LF4 is used as standard by leading manufacturers of racing equipment on piston running surfaces in damping elements. In addition to the required abrasion resistance, optimal friction properties are achieved.
polymeroxid®-LF4 produces the smoothest hard anodic layers on the market!
Because we can.
We can only achieve a consistently high quality standard by maintaining the stability of all process and bath parameters. Continuous in-house analysis of all process steps, PLC-controlled processes, a well-coordinated team and our unique plano ERP system are reflected in the highest possible quality.
We are also one of the few companies worldwide to have the IHAA Type II label for our anodized coatings!
This is how polymeroxid LF4® works
In the new process, the friction properties have been optimized for maximum smoothness, with a slightly reduced hardness compared to xH4®. This is where the completely new polymeroxid® matrix can fully exploit its advantages. LF4 is the process of choice when it comes to sliding applications and low breakaway torques are crucial.
polymeroxid®-LF4 produces the smoothest hard anodic layers on the market!
Details:
- completely new polymer oxide matrix
- smoothest hard anodized layers on the market
- high hardness of approx. 400 HV0.25 (7075-T6)
- protects against cold welding
- decorative design possible despite hard anodizing
- very high abrasion resistance
- reduces the slip-stick effect
- Excellent frictional properties
- Extremely good bonding properties with top coatings
The most suitable materials are AlZnMgCu1.5 (7075) and AlMgSi0.5/1.0 (6060/6082).
Die polymeroxid®–LF4-Schicht wächst zu 40% ihrer Gesamt-Schichtstärke über die Grundfläche hinaus (siehe Skizze). Eine 25μm Schicht bedeutet also ein Wachstum von ca. 10μm (20µm auf den Durchmesser). Die optimale Schichtstärke liegt zwischen 20 und 25μm.
Schichtstärken <20µm sind technisch nicht sinnvoll. Es haben sich zwei Schichtstärke-Klassen am Markt etabliert. (30 oder 50µm).
Der größte Teil der Werkstücke werden mit einer 30µm-Schicht veredelt.
Warum genau, weniger als 20µm und mehr als 50µm nicht empfehlenswert sind, erklären wir gerne in einem Beratungsgespräch.
Die effektiven Schichthärten sind stark vom verwendeten Werkstoff abhängig. Sie bewegen sich bei unserem LF4 in der Regel oberhalb von 400 MHV0,026 (70765 T6).
