Effect of cyclic strain on the mechanical behavior of virgin ultra-high molecular weight polyethylene.

Ultra High Molecular Weight Polyethylene (UHMWPE) is a polymeric material employed in critical biomedical applications. Knowledge of its mechanical behavior is essential in order to obtain accurate prediction of stresses and deformations in real components, in particular when cyclic loading is considered. In the present research the effects of alternating and pulsating cyclic strain on the mech...

Improvements of Ultra-High Molecular Weight Polyethylene Mechanical Properties by Nitrogen Plasma Immersion Ion Implantation

Nitrogen Plasma Immersion Ion Implantation (PIII) has been used to modify the surface chemical structure of Ultra High Molecular Weight Polyethylene (UHMWPE). Grinding and polishing processes based on abrasive papers and alumina pastes have been evaluated with regard to their results on the improvement of polymer surface roughness, which has shown to be of crucial importance for hardness charac...

Preparation and Characterisation of ZnO - SiO2 and Bi2O3 – CuO Nanocomposites

In the present work, ZnO - SiO2 and Bi2O3– CuO nanocomposites have been prepared by sol gel with alternate precursors existing in literature. They are characterised by XRD, SEM,UV, FTIR and photoluminescence  spectra .The XRD results indicate a crystallite size of  approximately 80 nm for both nanocomposites. SEM image shows a heterogeneous particle size for bot...
