DLC and carbon based nanostructured composite coatings – an overview of thin film design and process approaches towards high performance engineering applications

Stüber, Michael

Abstract (englisch):

Diamond like carbon coatings have nowadays reached high quality standards and are widely used in various industries. However, steadily increasing demands for advanced surface functionalities in high performance engineering applications require permanent progress in both thin films design and properties and related deposition techniques. Besides the enormous achievements made on amorphous carbon and DLC coatings enormous know-how and expertise has been collected on the new class of carbon-based nanostructured composites. In a fundamental view, these materials are at least two-phase composites, containing a nanocrystalline transition metal carbide and an amorphous carbon phase. Depending on their microstructural design (i.e. volume fractions of the crystalline and amorphous phases, grain size of the carbide phase, nature of the carbon phase, e.g. hydrogenated or non-hydrogenated) these new coating materials exhibit interesting multifunctional properties, making them promising candidates for various applications. Until today, these materials have been considered for and tested in selective technical environments only. In this presentation, major phases and achievements of the development of such materials will be discussed. ... mehr
