Notizen:
A nanoporous calcium phosphate (CaP) coating on metallic surfaces is presented. Thecoating consists of a stack of (a) a TiNbN layer deposited by physical vapor deposition and actingas diffusion barrier against allergenic ions, (b) a SiO2 xerogel layer providing good adhesionproperties and designing the nanoporosity of the outer CaP layer (c) precipitated electrochemically.SEM results verified a homogeneous nanoscale porous structure of the CaP coating. It ischaracterized by a high adhesion strength. If applied to stent covering the nanoporous CaP coatinghas promising properties to initiate rapid endothelium formation and reduced risk of restenosis
