Chromium-doped diamond-like carbon films deposited by dual-pulsed laser deposition

Popis výsledku v původním jazyce

Diamond-like carbon (DLC) and Cr-doped diamond-like carbon layers were studied. DLC and Cr- DLC were deposited on silicon and titanium substrates (Ti-6Al-4V) by dual-pulsed laser ablation using two KrF excimer lasers and two targets (graphite and chromium). The composition was analyzed using wavelength-dependent X-ray spectroscopy. The Cr content increased from 2.2 to 17.9 at%. The topology and surface properties as roughness of layers were studied using scanning electron microscopy and atomic force microscopy. With the chromium concentration increased the roughness and the number of droplets. Carbon and chromium bonds were determined by Raman spectroscopy. With an increase in chromium content the ID/IG ratio increased. Mechanical properties of DLC films with various chromium content were evaluated. Hardness (reduced Young?s modulus) was determined by nanoindentation and reached of 51 GPa (309 GPa).
