Study of laser created ZRO2 and hydroxyapatite/ZRO2 films for implantology
Original language description
Thin films ZRO2 and hydroxyapatite/ZRO2 were created by excimer laser ablation on Ti6Al4V substrates. ZRO2 layers were fabricated in vacuum by KrF laser at various substrate temperatures and hydroxyapatite (HA) layers were fabricated in water vapor ambient by ArF laser and in water vapor/argon ambient by KrF excimer laser. Film properties were evaluated by XRD, SEM and WDX methods. The test of mechanical adhesion was proceeded on ZRO2 films. XRD analysis proved the presence of amorphous or crystalline HA in the deposited films. SEM method demonstrated smooth surface covered by droplets for both HA and ZRO2 films. Ca/P ratio of the HA films is higher than that of the natural HA and is within the range of 2.8-3.0. The HA/ZRO2 and ZRO2 samples were testedin vitro for cytotoxicity. The best results were received by the HA/ZRO2 samples in the test of cytotoxicity.

Studie laserem připravených vrstev ZRO2 a hydroxyapatite/ZRO2 pro implantologii
Czech description
Tenké vrstvy ZRO2 a hydroxyapatitu/ZRO2 byly připraveny excimerovou laserovou ablací na podložky Ti6Al4V. ZRO2 byl připraveny ve vakuu KrF laserem při různých teplotách podložky. Vrstvy hydroxyapatitu (HA) byly připraveny v přítomnosti vodních par laserem ArF a v okolí vodní páry/argon laserem KrF. Vlastnosti vrstev byly studovány pomocí XRD, SEM a WDX metod. Na vrstvách ZRO2 byl prováděn test mechanické adheze. XRD analýza zjistila krystalické nebo amorfní fáze HA. Metodou SEM byl zjištěn hladký povrchpokrytý kuličkami a to jak pro vrstvy HA, tak i pro ZRO2. Poměr Ca/P v HA vrstvách byl vyšší než je tomu u přírodního HA a byl v rozsahu 2,8-3,0. Vzorky HA/ZRO2 a ZRO2 byly testovány in vitro na cytotoxicitu. Nejlepší výsledky cytotoxicity byly získányna vrstvách HA/ZRO2.
