Application of Tribometry in Investigations of Biomaterials

Abstract

Development of materials for manufacturing of the chirurgical implants in medicine - biomaterials (metals, polymers, ceramics and composites) is directly determined by characteristics and nature of the tissue, organs and systems that are being replaced or supplemented. Modern material investigations at micro-and nano-level enable introspection into new aspects of material behaviour and offer possibilities to significantly improve systems in use, from different aspects of changes in material production technologies or application of surface technologies modifications or coating technologies. Biomaterial investigations from a tribology point of view offer contribution to testing realised in this area, especially with use of novel devices for research in area of nanotribology. In this paper, some tribological characteristics of Ti-6Al-4V alloy, aimed for medicine applications, are presented. Investigation is realised at CSM nanotribometer in accordance with testing conditions significant for this type of biomaterial.
