In vitro degradation of ZnO flowered coated Zn-Mg alloys in simulated physiological conditions

Original language description

Flowered coatings composed by ZnO crystals were successfully electrodeposited on Zn-Mg alloys. The distinct coatings morphologieswere found to be dependent upon the solid interfaces distribution,with the smaller number of bigger flowers (? 46 ?m) obtained on Zn-Mg alloy containing 1 wt.% Mg (Zn-1Mg) contrasting with the higher number of smaller flowers (? 38 ?m) achieved on Zn-Mg alloy with 2 wt.% Mg (Zn-2Mg). To assess the in vitro behaviour of these novel resorbable materials, a detailed evaluation of the degradation behaviour, in simulated physiological conditions, was performed by electrochemical impedance spectroscopy (EIS). The opposite behaviours observed in the corrosion resistances resulted in the build-up of distinct corrosion layers. The products forming these layers, preferentially detected at the flowers, were identified and their spatial distribution disclosed by EDS and Raman spectroscopy techniques. The presence of smithsonite, simonkolleite, hydrozincite, skorpionite and hydroxyapatite were assigned to both corrosion layers. However the distinct spatial distributions depictedmay impact the biocompatibility of these resorbablematerials,with the bone analogue compounds (hydroxyapatite and skorpionite) depicted in-between the ZnO crystals and on the top corrosion layer of Zn-1Mg flowers clearly contrasting with the hindered layer formed at the interface of the substrate with the flowers on Zn-2Mg.
