Thin, hard amorphous carbon (aC) layers were the object of investigations, in particular the
microstructure of the layer in the carbon layer-steel substrate system with the aim of
optimization of the synthesis and applicability of this new system for medical implants. The
results of Auger electron spectroscopy studies show that the composition of the layer is
complex. It consists of carbon and a transitional layer containing both carbides and carbon
regions. The structure of the coatings ensures a high mechanical strength and very good …
