Various bone cements with different compositions were prepared in several model configurations which differed in volume (i.e. setting temperature profile) and mode of mixing (manual and vacuum bowl). The wear behaviour of all states was studied using pin-on-disc technique and related to microstructure and local mechanical properties (nano- hardness, elasticity modulus) measured by nanoindentation. The results were compared to a natural biological material. The role of the preparation route as well as influence of composition, particularly of the presence of antibiotics, on the measured properties was investigated. The results are discussed with respect to the possibilities of using the advanced technique of cutting by water jet in orthopaedic surgery.
