dc.description.abstractBiomaterials are synthetic materials used to replace part of a living organ or to function in intimate contact with living tissue. Titanium and Ti-6Al-4V alloy are among the most commonly used implant materials, because of the good corrosion resistance, excellent strength and ductility. Elements of Ti-6Al-4V alloy cause allergic response and degeneration of muscle tissue. The subsequent release of these elements into the body system is fatal for the long term application of this alloy in the human body. Therefore, the aim of this study was to improve the structure properties and the biocompatibility of bioceramic coated Ti-6Al-4V by using radio frequency plasma technique RF. Annealing of the as-sputtered films was necessary to change the amorphous coating to a crystalline coating. After annealing, the morphology, the thickness, the roughness surface and structure analysis of these films were characterized using the Field Emission Scanning Electron Microscopy (FESEM), Atomic Force Microscope (AFM) and X-ray diffraction (XRD), respectively. At annealing 800 , FESEM, AFM and XRD showed free of cracks and pores in the HAp, thin film coated Ti-6Al-4V alloy and the following Miller indices (hkl): (002), (211), (301) and (004), respectively. They belong to the HAp phase which proved the data reported for hexagonal (JCDS–ICDD file # 09-0432). TiO2 phase was the dominant phase in all XRD patterns of TiO2 coated Ti-6Al-4V alloy at annealing 800 . The hardness of the untreated and treated specimens was determined by Vicker’s hardness. After annealing, the hardness values of the bioceramics materials (HAp, ZrO2 and TiO2) coated Ti-6Al-4V alloy were 780, 560 and 470 Hv, respectively.en_US
