Zusammenfassung:	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 a 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. Procédé d'application de revêtement en hydroxyapatite sur un implant médical comprenant les étapes consistant à : (a) traiter au plasma ledit implant médical à l'aide d'un bain d'oxydation par plasma électrolytique dans un électrolyte; (b) appliquer un revêtement en hydroxyapatite sur un implant médical traité au plasma dans un réacteur hydrothermique sous pression; (c) laver un implant médical revêtu d'hydroxyapatite; et (d) sécher un implant médical lavé. L'étape a) et/ou l'étape b) comprend en outre une sous-étape consistant à former des germes de cristallisation sur une surface dudit implant médical.
