The article is focused on the new polymer material which could be used for hip endoprosthesis. Nowadays the most common materials which are used are metal alloys, ceramics and polyethylene. The aim of this study was to present the properties of modified polycarbonate (PC) with the particular consideration of tribological and mechanical properties and proving that this material could be successfully used beside existing and currently chosen materials. For mentioned materials conducted a few tests. Among of them were hardness measurements, static stretching tests and study of abrasive wear resistance. Obtained results allowed to conclude about using the material as not only a part of hip endoprosthesis but a whole implant. The novel obtained polymeric materials based on the PC modified with nanosilica presents instead of bacteriostatic properties improved resistance to volumetric wear. The nanoparticles of silica do not negative affect on the friction coefficient. The obtained results clearly presents that the material possess better coefficient of friction combined with lower volumetric wear. |
