Thermal sprayed coatings for increase of friction coefficient

Reibungssteigernde Beschichtung für Welle-Nabe-Verbindung
Verschleißschutzbeschichtungen mit hohem Reibwert für PKW-Bremscheiben

Similar to rough coatins in transport components, also thermal sprayed coatings are capable of increasing the friction coefficient for mating machine parts.

Under the brand name f-CER®, GfE offers coatings with a specifically high static friction coefficient against steel and other construction materials.  These GfE-manufactured ceramic layers are used, for example, in shipbuilding and vehicle construction, printing press engineering and the textile industry.  While steel-to-steel mating is usually designed with a friction coefficient of μ = 0.10...0.12, systems with f-CER® coating reach values far beyond µ = 0.5. Here are some of the resulting advantages:

  • Compact design
  • Lower manufacturing costs
  • Higher operational safety
  • Energy savings due to reduced moving masses

Metal and hard metallic coatings have proved especially effective for dynamically stressed friction systems such as brake discs and clutch elements. Next to a friction coefficient that remains constant over a wide temperature range, they provide excellent wear resistance and adhesion.

Here´s an overview:
