INFLUENCE OF CARBON COATINGS ORIGIN ON THE PROPERTIES IMPORTANT FOR BIOMEDICAL APPLICATION

The purpose of the present study was to investigate the properties of a carbon layer depending of the origin of applied methods. Quasiamorph ous carbon coatings prepared by ion beam methane decomposition by RF d ense plasma and vacuum pulsed are deposition were applied to stainless steel implants used in surgery. The studies of carbon films as coatin gs for implants in surgery were aimed on the investigations of biologi cal resistance of implants, histopathological investigations using lab oratory animals, tests of corrosion resistance, measurements of mechan ical properties and a breakdown test in Tyrod solution. The comparison of the properties of the coating produced by these methods shows very good biotolerance and biocompatibility of all of the coatings. They a re not corroded in physiological fluids. From the other side they have different properties, especially electrical and optical, and are not influenced on medical applications. The obtained results prove that th e implants coated by all the methods mentioned are a very good materia l for medical use.
