Beschreibung
Zusammenfassung:	The present invention is directed to metal articles and methods of making the metal articles. The metal articles comprise a compression-formed particulate metal object, wherein a portion of the compression-formed particulate metal object has been selectively removed by an etching process from at least one surface of the object. The etching process is frequently performed using abrasive etching.
