An implant and method for producing an implant, in particular an intraluminal endoprosthesis, with a body, wherein the body contains iron or an iron alloy, comprising the following steps:a) providing the implant body (1),b) applying a metallic coating comprising as main constituent at least one element of the group containing tantalum, niobium, zirconium, aluminum, magnesium, vanadium, molybdenum, hafnium, and wolfram onto at least a portion of the body surface, andc) plasmachemical treatment of the portion of the body surface provided with the coating in an aqueous solution for producing a plasmachemically generated layer (3, 5, 7) by means of applying a plasma-generating pulsating voltage to the body of the implant, wherein the pulsating voltage has sufficient energy that the metallic coating (3, 5, 7) is temporarily and sectionally ionized up to the underlying implant body (1) in such a manner that the generated layer has pores (5) which extend at least partially up to the implant body.
