<p>The implant comprises an implant body containing biodegradable metallic material such as iron (99 wt.%). A portion of the surface of the implant body has a first coating formed from a composition containing strontium and calcium. The first coating has a thickness of 1-5 mu m. The implant contains implanted nitrogen in the first coating and the implant body. The integrated nitrogen content from the surface of the strontium/calcium coating down to a depth of 5 mu m is optionally 0.1-1.5 wt.%. On the first coating, a second coating containing an acid-degradable polymer is additionally provided.
