Summary

Hydroxyapatite [Ca10(PO4)6(OH)2] coatings were deposited on alumina substrates under hydrothermal conditions at 90°C from aqueous solutions of calcium nitrate and ammonium hydrogen phosphate containing EDTA disodium salt as a chelating agent and hydrogen peroxide. The influence of the solution pH and time on the deposition of the coatings was investigated. The nucleation and growth, structure and composition of the coatings as well as the bonding of the coating to the substrate were investigated using electron microscopy, X-ray diffraction, and surface chemistry techniques. The deposition mechanism of the coatings is discussed.
