| Abstract: | The properties of kinetic clotting, platelet consumption and hemolysis of Ti6Al4V- TiN and Ti6A14V- TiC and other biomaterials were measured in vitro. By comparing the haemocompatibility of each material, following conclusion was obtained: (1) According to the values of kinetic clotting, LTI Carbon > DLC coating > TiN>TiC>Ti6A14V. (2) Depending the on data of platelet consumption. LTI Carbon > DLC coating >TiN>Ti6A14V>TiC. (3) Based on the rates of hemolysis, LTI Carbon >DLC coating >TiN> TiCk Ti6A14 V. |
