## Description

- description: Carbonate apatite (CAp) coating has been developed as a bioabsorbable
    corrosion-control coating for biodegradable Mg alloys. Carbonate content in the
    CAp coatings can be utilized to control the bioabsorbability and corrosion rate
    of CAp-coated Mg alloys. In this study, the carbonate content in the CAp coatings
    of pure Mg was varied by NaHCO3 concentration of the coating solution from 0.25
    to 1.0 mol/L, and hydroxyapatite (HAp) was formed without NaHCO3. The CAp and
    HAp coatings were characterized using X-ray diffraction (XRD), X-ray photoelectron
    spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). The carbonate
    content in the apatite coatings formed with 0, 0.25, 0.5 and 1.0 mol/L NaHCO3
    was determined to be 2, 12, 15 and 18wt%, respectively, from the apatite 002 plane
    XRD peak position using the existing conversion constant as well as from the coating
    composition obtained by the XPS analysis. The values of carbonate content obtained
    by each method were in good accordance, indicating that the carbonate content
    can be determined simply by XRD measurements. Two types of carbonate group were
    present in the CAp coatings, CO32- and HCO3-, and the relative content of HCO3-
    to CO32- increased with an increase in the carbonate content.
