Abstract
Development of biocompatible coatings on implant surface is an essential and urgent problem. Coatings based on titanium oxynitride formed by means of reactive magnetron sputtering are used as the biologically inert material for surgical products. Oxynitride coatings are suitable for use under the conditions of long-term contact with biological liquids. The characteristics (corrosion stability, film solubility) of Ti-O-N coatings deposited on the substrates by means of reactive magnetron sputtering were investigated. The coatings and the compositions of model liquids formed as a result of the dissolution of titanium oxynitride films in physiological liquids were studied by means of infrared and gas spectroscopy, atomic emission analysis. It was established that the samples of Ti-N-O biocoating contain nitrogen, and the solutions contain nitrogen oxide NO, the molecule which is vitally necessary for living organisms.
