Effect of Electromagnetic Induction Deposition's Heating Time of Magnesium-Hydroxyapatite Coating on Carbon/Carbon Composites

摘要

This study investigated the different effects of deposition time of electromagnetic induction on a coating containing magnesium hydroxyapatite (Mg-HA) on the surface of carbon/carbon composites. SEM, EDS, X-ray diffraction, Fourier transform-infrared spectroscopy, and other analyses were carried out 0.5, 1, 2, 4, and 8 h after electromagnetic induction deposition to characterize the coating. The density of the coating increased with increasing deposition time, which enabled the magnesium ions to enter the HA crystal. The coating contained micropores with a size of about several hundreds of nanometer after 2 h of electromagnetic deposition induction, and the content of magnesium was 0.36%. The increase in the number of osteoblast cells (MC3T3-E1) on the coating surface was high, and their adhesion was also good. These results provide technical support for the selection of suitable electromagnetic induction deposition time.
