Abstract
Relation between blood compatibility of sputter deposited metals and their surface charge, wettability and roughness was investigated. Materials tested were: (1) titanium (Ti), nickel, copper and aluminum and (2) composite metal of Ti and the above metal. Blood compatibility of the materials was evaluated by the in vitro “kinetic test”. Findings were: (1) Blood compatibility of the metal, which is low in the electromotive series was better than that higher in the series. (2) Antithrombogenecity of the composite metal was better than that of Ti. (3) No good relation between blood compatibility and wettability or surface roughness was obtained.
