Abstract:

BACKGROUND: Plasma spraying, sol-gel coating process and ion beam sputtering are often used for making coatings on the surface of titanium alloy, but the properties of the coatings are unstable, the composition is homogeneous, and the control of the phase composition is difficult.
OBJECTIVE: To prepare HAF/YSZ gradient composite coatings on Ti6Al4V substrate by radio frequency magnetron sputtering.
METHODS: The HAF/YSZ gradient composite coatings were deposited on Ti6Al4V substrate by radio frequency magnetron sputtering. X-ray photoelectron spectrum, electron probe, and scanning electron microscope were used to investigate the composition distribution, surface morphology and interface morphology of the coatings. The biological activity and stability of HAF/YSZ coatings, HAF1.2 coatings and HA coatings were analyzed and evaluated in siulated body fluid.
RESULTS AND CONCLUSION: The prepared HAF/YSZ gradient coatings could provide well grow conditions for fresh osseous tissue based on their porous structure and rough surface. The interface was closely combined with the coatings. Interdiffusion existed between layers, and the overall consistency was better. New substances deposited on the surfaces after immersing in siulated body fluid, which showed better biological activity and stability of HAF/YSZ gradient coatings. The anti-solubility and stability of HAF/YSZ coatings were better than that of single fluorine content coatings.
