Název v původním jazyce

Morphology, antibacterial and mechanical properties of silver doped diamond like carbon prepared by dual pulsed laser deposition

Popis výsledku v původním jazyce

Silver doped diamond-like carbon layers (Ag-DLC) were deposited on silicon (Si 100), fused silica and titanium substrates (Ti-6Al-4V) by dual pulsed laser ablation (dual-PLD) using two KrF excimer lasers and two targets (graphite and silver). The composition and structure was analyzed using wavelength-dependent X-ray spectroscopy and X-ray diffraction. The Ag content increased from 1.0 at.% to 10.6 at.%. Carbon and silver bonds were determined by X-ray photoelectron spectroscopy. The topology and surface properties as roughness of layers were studied using scanning electron microscopy and atomic force microscopy. With the silver concentration increase the roughness and the number of droplets increased. The mechanical properties of Ag-DLC films have been investigated. Hardness and reduced Young's modulus was determined by nanoindentation. The layer hardness, reduced Young's modulus and adhesion (tested with scratch test method) increased with the decreasing silver content. Three liquids
