Preparation of Bioactive Calcium Phosphate Coatingon Porous C/C Substrate by a Novel Deposition Technique

摘要

A novel heat substrate technique,high frequency inductive heat deposition(IHD),was introduced to coat porous carbon materials,C/C and carbon felt to improve their bioactivity.The morphologies, composition and microstructure of the resulting coatings were examined by scanning electron microscopy(SEM), energy dispersive spectra(EDS),X-ray diffractometer(XRD)and Fourier transform infrared spectroscopy (FTIR).The results show that,the calcium phosphate consisted of non-stoichiometric,CO3-containing and plate-like octacalcium phosphate(Ca 8-x H 2 (PO 4 ) 6 ,OCP)could uniformly cover the entire porous surfaces of carbon materials.Good adhesion of the coating to carbon material substrates was observed.
