정전기분사 증착법을 이용한 Hydroxyapatite (HA) 코팅에 관한 연구 = A Study of Hydroxyapatite (HA) Coating by electrostatic Spray Depositon

다국어 초록 (Multilingual Abstract)

Coatings of hydroxyapatite (HA) on titanium substrate have been conducted by electrostatic spray deposition (EDS). Electrostatic spray deposited HA films on Ti were heat-treated (400~900) and their physical characteristics were investigated by Scanning Electronic Microscopy (SEM), X-ray Diffractometer (XRD), and X-ray Photoelectronic Spectroscopy (XPS). The precursor of solution for the HA coating by ESD was prepared by mixing of nano-sized HA powder with ethyl alcohol. As-deposited HA films were consisted of HA particles which were distributed uniformly on the Ti substrate, showing a porous structure. By heat treatment (400~900oC), less porous and crystalline HA films were formed on Ti substrate. Major surface elements on the heat treated HA samples were Ca and P in the form of HA. It is concluded that EDS can be applied to the formation of uniform and crystalline HA films on Ti substrate.
