摘要

Calcium phosphate (CaP) ceramics, e.g. hydroxyapatite Ca_(10)(PO_4)_6(OH)_2 (HAP) and tricalcium phosphate Ca_3(PO_4)_2 (TCP), are widely employed in the field of bone tissue engineering due to their controlled biodegradability and excellent biocompatibility. In the present study, the chemical composition, microtexture and structure of CaP deposits on carbon fiber cloths (CFC) are investigated. Coatings of CaP or strontium-substituted calcium phosphate (Sr-CaP) on CFC are obtained by sono-electrodeposition process using cathodic polarization. At constant potential, the deposits consist in a biomimetic carbonated calcium-deficient hydroxyapatite (CaD-HAP), having a plate-like morphology with the possibility to control the Sr~(2+) incorporation. In orthopaedic field, CaP or Sr-CaP coated carbon fiber cloths offer new promising bioceramic materials for bone repair and regeneration.
