Customized surface technology for innovative automotive and industrial products
Modern components and systems for automotive and industrial applications have to meet various requirements in multiple technical fields. Apart from properties that affect the part itself- like geometry, stiffness, weight or rigidity - the surface properties must be adjusted to the growing environmental requirements. Therefore coatings are increasingly applied to reduce the friction losses of car components, improve fuel efficiency and reduce CO2-emissions. This article describes how to use surface technology as a modern design element for components and systems to enable the demanding requirements on market leading automotive and industrial products. Therefore Schaeffler has developed and established a coating tool box for customized surfaces to deliver the right solutions for all that needs and requests with the corresponding coating system enabled by PVD-/ PACVD-, spraying or electrochemical technology. For innovative products it is extremely important that coatings are considered as design elements and integrated in the product development process at a very early stage.In this article tribological coatings are viewed within a holistic and design-oriented context. The latest developments of amorphous carbon coatings, their characteristics as well as the technical and economical effects of their use in combustion engines and industrial bearing applications are described.The presented Triondur* amorphous carbon based coating systems (a-C:H; a-C:H:Me; a-C:H:X and ta-C) are excellent examples for customized tribological systems like bucket tappets, linear guidances and roller bearings.Triondur* carbon coatings offer the following advantages: super low friction with highest wear resistance, customized surface energy, optimized wetability and interaction with formulated engine oils and low adhesion to the counterpart. A close collaboration between designers and surface engineers is required in the future. Schaeffler delivers around 75 million high-quality PVD- and (PA)CVD-coated components (Triondur?) every year that enable outstanding applications,preserve resources and meet increasing customer requirements.
