Purpose: The main purpose of the paper was evaluation of antithrombogenic properties of the passive-carbon layer used for enhancing the surface properties of vascular stents made of Cr-Ni-Mo steel. Design/methodology/approach: In vitro tests of biotolerance evaluation of the passive-carbon layer in blood environment have been carried out on the basis of haemolysis tests (in the direct contact and from the extract) and blood clotting tests. Findings: The carried out investigations have shown that deposition process of the passive-carbon layer which has dielectric properties on the surface of implants made of Cr-Ni-Mo steel and used in interventional cardiology is an effective way in limiting the reactivity of their surface in blood environment and the blood clotting process in consequence. Research limitations/implications: The carried out investigations should be completed with biotolerance in vivo investigations. Originality/value: Modification of physical properties of surface of the metallic biomaterials applied in cardiovascular system by deposition of the passive-carbon layer of dielectric properties limits the blood clotting process.
