摘要:
A method for the plasma electrolytic oxidation of a bioactive coating onto implant(4) is provided. The implant is placed in an electrolyte solution (3) providingCa and P ions and then connected to a power supply (1). A counter electrode is alsoprovided in the electrolyte solution. A sequence of voltage pulses having alternatingpolarity are then applied across the implant and counter electrode to deposita bioactive coating onto the implant. A intra-bone implant formed by the methodis also provided having a coating with a thickness of 10 to 30 microns, a porositycomprised by pores with sizes of 0.5 to 10 microns, and comprising 10 to 30 wt% ofhydroxyapatites.
