Abstract

Background: Titanium and its alloys have been used in biomedical applications because of their biocompatibility and mechanical properties. However, It has a possible toxic effect resulting from released vanadium and aluminum. The (HAP) coated Ti-6Al- 4V alloy prevented releasing of undesirable ions.

Objective: The aim of this paper is to investigate the structural and mechanical properties of Ti-6Al-4V alloy by coating with (HAp). This coating was prepared by Radio Frequency Plasma Sputtering (RF) method.

Results: The thin film of HAp was annealed at temperature of 800 C° to improve the structural, composition, roughness and hardness were characterized by X-ray diffraction (XRD), Field Emission- Scan Electron Microscope (FE-SEM), atomic force microscope (AFM) and Vickers hardness respectively. The HAp films were amorphous.

Conclusion: After annealing at 800 C° the surface amorphous of HAp was converted to crystalline structure. AFM and the Vickers hardness showed different roughness and hardness of Ti-6Al-4V when uncoating, as-deposited HAp thin film and after annealing.

Keywords: Ti-6Al-4V; hydroxyapatite coating; crystal growth; RF plasma
