XRD and Raman spectrum of bioactive calcium phosphate coatings on carbon/carbon composites by sonoelectrodepostion technology

Bioactive calcium phosphate coatings on carbon/carbon composites were prepared by sonoelectrodepostion. The characteristics of these coatings obtained with different ultrasonic powers were explored by XRD, EDAX and Raman spectrometry. Results showed that the aberration of the crystal lattice occurred for the calcium phosphate coating prepared by sonoelectrodepostion. Chemical bonds, such as COP and COH, were formed between C/C composites and calcium phosphate. Additionally, the mechanism of the reaction is a combination of sonoelectrochemical modification, sonochemical synthesis and electrocrystallization.
