AbstractThis work aim to preparing NiTi/PVA composite nanofibers by electrospinning technique, using a novel method of producing NiTi ultrafine particles by immersing sintered NiTi alloy for a specific time in dilute aqua regia solution (3HCl: HNO3), in which these produced NiTi ultrafine particles are used in the electrospinning process. The electrospun materials provide a fibrous structure that improves adhesion with cells through the high surface area to volume ratio. The produced ultrafine NiTi particles were analyzed by X-ray diffraction (XRD), Energy dispersive spectroscopy (EDS), and Particle size analyzer. The XRD pattern of ultrafine NiTi particles showed much better phases as compared to the XRD pattern of the NiTi alloy sample.

In this study, the preparation of porous scaffolds from hydroxyapatite (HAp), 13-93 bioactive glass (BG), and functionally graded material (FGM) from both of them have been accomplished using the infiltration technique of polyurethane sponge. The obtained results show that the EDX analysis of FG samples is promoted graded of chemical compositions for HAp and 13-93BG. SEM showed that all prepared scaffolds have a highly interconnected porous structure with specific porosity gradients, about 73±2 %, 83±2 %, and 79±2 % for HAp, BG, and FGM scaffolds, respectively. Finally, the biocompatibility results were investigated in vitro involved the cytotoxicity by using MTT assay; the results demonstrated non-cytotoxic excretion for the scaffolds against the human osteoblast.

Mohammed” from the Department of Materials Engineering/University of Technology, due to their distinguished efforts in achieved a patent, according to book No. A.N.A/232 dated 14/12/2021.
The title of patent: “Manufacture of material as implants within the human body from polyetheretherketone (PEEK) as substitutes for metal implants”.
Nanoindentation is a powerful technique to determine various mechanical properties of materials at the nanoscale, such as for example young’s modulus and hardness. Polyetheretherketone (PEEK) is a material that is widely used in medicine because its mechanical properties show excellent similarity to those of human bone. The main objective of this study is to conduct a manufacturing experiment nano polyetheretherketone composite for characterization of its mechanical properties using a tensile test and nanoindentation techniques of mechanical tests. The results of mechanical tests exhibit improvements of youngs modulus, hardness and ultimate tensile strength at 1.5 wt % for two types of reinforcement but the higher values obtained when reinforced by (nHA).

This research attempts to study the influence of annealing, precipitation hardening, and nitriding treatments on monotonic and repeated characteristics and microstructural inspections of AA6061. Quenching mediums are water, local freezer, dry ice, and liquid nitrogen. Ageing temperatures of (170, 200, and 230)°C are used for intervals of (2, 4, 6, 8, and 10) hours. Plasma nitriding treatment was performed on alloy to enhance its hardness and wear opposition. The best ageing interval is (6) hours. Hardness, impact and fatigue resistance are improved after nitriding and quenching in liquid nitrogen.
