The invention relates to a method for coating an implant (1), in particular a prosthesis, by applying charged particles (T) by means of iontophoresis to at least one section (10, 20 110, 120) of the implant surface (3, 13). In the method, charged particles are accelerated in an electromagnetic field (E) and hit the surface (3, 13) of the implant in order to form a coating on the implant at least in some sections. The charged particles have at least one active ingredient.
