| Summary: | The objective of the study is assessment of suitability of the ALD method for application of a TiO2 layer on surface of 316LVM steel used for production of vessel stents. Selection of the appropriate process parameters for application of the layer affects its electrochemical properties, which largely determine resistance of the biomaterial to corrosion in the blood environment, thus affecting its hemocompatibility. To assess resistance of the AISI 316LVM steel with modified surface to corrosion, voltammetric and impedance measurements were conducted. The proposed variant of surface processing allows safe deformation of the TiO2 layer without its delamination. |
