Apatite (DAp) was formed on stainless steel through a two-step process, i. e., electrodeposition of brushite (DCPD) and its conversion into DAp in solution. The deposition of DCPD was conducted by electrolysing an acidic calcium phosphate solution at constant cathodic currents of 2.0 and 5.5mA/cm2 at 30°C. The conversion of thus deposited DCPD into DAp was carried out by soaking in an alkaline solution. The adhesiveness of DCPD deposits to the cathode substrate was points 8~10 by the square scratching test and 9~10 by the adhesive tape detaching test. The adhesiveness of converted DAp was points 0~4 by the tape detaching. While, that of a directly deposited DAp was 8~9.
