Severe plastic deformations lead to structural transformations in dense microcrystalline hydroxyapatite (HA, Ca10(PO4)6(OH)2) ceramics and particularly to formation of nanocrystalline structure with α-tricalcium phosphate (α-TCP) and amorphous calcium phosphate (ACP) inclusions. In the present work we studied the substructure and hardness of ceramics using nanoindentation and Transmission Electron...
Despite the numerous literature data available in the field of calcium phosphate bone cements, the mechanism and kinetics of their hardening, both of which are of great importance for cements application, in most cases, is unknown. In this work, the mechanism and kinetics of hardening of two novel high‐strength calcium phosphate bone cements were studied using the energy dispersive X‐ray diffraction...
Calcium phosphate coatings are known to enhance long-term fixation, reliability and promote osteointegration of cementless titanium-based implant devices. This study was aimed at the pulsed laser deposition of calcium phosphate coatings onto titanium using hydroxyapatite and hydroxyapatite-fluorapatite targets. The deposition was carried out at the high laser beam fluence conditions, about 12J/cm...
