Abstract

The hemocompatibility of an implant is determined by its surface properties. Diamond like carbon surfaces (DLC) are slowing thrombin development due to their low values of surface energy. Magnetron sputtering (MS) and plasma enhanced chemical vapor deposition (PECVD) are the techniques successfully used in this type of applications. In this paper we have studied carbonic hemocompatible adherent structures onto metallic substrates of stainless steel and titanium. The carbonic structures have been characterized by FTIR, AFM, scratch test and pull-test adherence test. Surface energy was estimated by the contact angle method and the clotting time by the droplet method..
