Centre of Competence for Surface Technology

Schaeffler is a world leader in competence for functional surfaces and coatings. With the expansion of the Centre of Competence for Surface Technology at Herzogenaurach, Schaeffler has increased its capacity in the field of development and application of coating technology – with the objective of further extending its technological and market leadership in this field.

 
With Triondur® CX+, Schaeffler succeeded in reducing by half the friction losses in the car valve train and thus achieving valuable savings of one to two percent in CO2 from the car.
 
Through the use of Triondur® CX+, rolling bearings can run free from wear and with only low friction under extreme conditions. The friction values in spherical roller bearings were reduced by up to 45 %.
 
 

The Centre of Competence for Surface Technology opened in 2007 and has shown highly successful development in recent years. One piece of evidence: since then, sales of coated parts have increased by more than 50 percent. We now offer an extensive modular range of concept that allows us to design the surfaces of components and systems in precise accordance with the specific requirements of our customers. Our systems increase the lifetime of components and offer protection against wear, corrosion and electrical current passage. In addition, they reduce friction and thus make a considerable contribution to conservation of resources and energy efficiency.

The latest developments allow the use of multi-functional and sensory coatings. With our technical resources and our know-how in processes and applications, we are able to provide samples at an early stage in the development path and achieve direct, robust implementation of these in a volume production environment.

This is true both for relatively small batch sizes for industrial applications and for the production of millions of pieces typical of the automotive industry.

One example: Triondur® CX+. This new type of coating system makes it possible to reduce by half the friction losses in car valve trains over the entire lifetime in closely coordinated interaction with the engine oils used worldwide and thus achieve valuable savings of one to two percent in CO2 in cars. Through the use of Triondur® CX+, rolling bearings can run free from wear and with only low friction under extreme conditions. In this way, the friction values in spherical roller bearings can be reduced by 45 % and the bearings exhibit low friction values even under lubricant starvation that would otherwise only have been achievable with a good level of lubrication. Since it is only necessary to apply a coating to one of the friction surfaces, such as the tappet or the bearing rollers, Triondur® CX+ can be used economically and in a modular fashion. This innovative strength and the added value for the customer are reflected in the rapid progress of the coating system across the market and in the the continually rising quantities, which are already at more than 20 million pieces per year.

For the new coating system Triondur® CX+, Schaeffler received the "Materialica Design + Technology Award 2012" in the category "Surface + Technology" at the Materialica 2012 show in Munich.
