Abstract
Xenogeneic bone-derived hydroxyapatite (HA) was coated on Ti–6Al–4V substrate using aerosol deposition (AD) system. HA precursor powder was derived from bovine bone for the deposition. In aerosol system, submicron particles of HA were mixed with a carrier gas to form an aerosol flow in the aerosol chamber. The aerosol flow was through a tube to a nozzle, and then ejected into a deposition chamber. The effect of the beam incident angle on the HA film formation was investigated. The incident angle of the beam was changed from 0° to 60°. Homogeneous HA film with the thickness of 1-2 μm was fabricated by flattering of particles shape for the incident angle of 60°.
