Abstract
A method of coating a medical implant with hydroxyapatite comprises steps of: (a) plasma treating said medical implant by a plasma electrolytic oxidation bath within an electrolyte; (b) hydroxyapatite coating a plasma treated medical implant in a hydrothermal pressurized reactor; (c) washing a hydroxyapatite coated medical implant; and (d) drying a washed medical implant. At least one of steps a and b further comprises a sub-step of forming crystallization seeds on a surface of said medical implant.
