Studies of Mechanical Treatment on Surface Charge of Bioactive Composites

Composite materials containing a bioactive phase (sol-gel-derived bioglass) and a mechanical strength phase (aluminum oxide-porous corundum) are promising materials for repair of living tissues. The influence of mechanical treatment of composite structure containing sintered corundum and CaOSiO2-P2O5 glass system was examined by exoelectron emission and electrokinetic’s potential method. The microstructure of the biocomposite material, its mechanical properties and the processing techniques used are all very strongly interrelated.. The charge layer generated on the surface of the composite biomaterials upon deformation and the type of the electrical charge in implants plays significant role…
