The workpiece blank has base body which is provided with surface and oxidation protection layer disposed on at least a portion of surface. The base body comprises a refractory metal. The oxidation protection layer is composed of metal such as iron or iron alloy. The oxidation protection layer is deposited on the surface of the base body by process selected from the group consisting of plasma spraying, atmospheric plasma spraying, electric arc spraying, flame spraying, and cold gas spraying. An independent claim is also included for a production method of workpiece blank. Die vorliegende Erfindung betrifft Formteilrohlinge aus einem Grundkörper, der aus mindestens einem Refraktärmetall und einer Oxidationsschutzschicht aus mindestens einer Metallschicht besteht sowie ein Verfahren zu deren Herstellung.
