Notes:
In recent years, nanostructured coatings by Plasma Thermal Spraying (PTS) attractedintense interest due to their enhanced mechanical properties as hardness, strength and ductility.The aim of this study was to evaluate the influence of coating the implant by nanohydroxyaptite,n-HAp, Ca10 (PO4)6(OH)2. The results obtained with n-HAp will also compared withthe implant coated with HAp. Bone is a composite material in which are associated a mineral phasein the form of crystals of HAp and an organic matrix constituted by collagen. The c-axes of HApand the collagen fibers are preferentially oriented in the direction of the stresses that the bones needto withstand. At the interface implant-bone, the new bone reconstituted after implantation musthave the same proprieties of the original bone in order to have good fixation with the implant.Therefore, it is necessary to study the mechanical properties of this new bone crystals reconstitutedat the interface with the implants coated with n-HAp and HAp by neutrons diffraction on D20 atILL
