Titanium Oxynitride Coatings Deposited By Magnetron Sputtering For Improvement Of Cardiovascular Stent Design

Abstract

The aim of this work was to develop a new type of stent with improved characteristics, made of stainless steel coated with TiOxNy film deposited at different O2:N2 ratios (1:2; 1:5 and 1:10) in a reactive atmosphere of abnormal magnetron discharge. Argon (Ar) has been used as a plasma-forming gas. The publication presents the results of investigation of the properties of TiOxNy coatings by means of analytical and in vitro methods containing recommendations regarding application of these kind of coatings for stent implants.
