Influence of diamond and graphite bonds on mechanical properties of DLC thin films

Popis výsledku v původním jazyce

Mechanical properties of diamond-like carbon thin films with various ratios of sp3/sp2 bonds were studied. The films were prepared in argon atmosphere (0.25 Pa) by laser deposition method for laser energy densities from 4 J*cm-2 to 14 J*cm-2. The sp2 andsp3 bonds were calculated by X-ray photoelectron spectroscopy. Films contained sp3 bonds up to 70 %. Surface properties as roughness and atomic force microscopy topology were measured. Hardness (and reduced Young's modulus) were determined by nanoindentation and reached of 30 GPa (203 GPa). Films adhesion was studied using scratch test and was up to 12 N for Ti-6Al-4V substrates. Relations among deposition conditions and measured properties are presented.
