Document Type and Number:
WIPO Patent Application WO/2016/098087
Kind Code:
A3
Abstract:
The invention relates to a method for producing round stock (10) which is provided with at least one inscription and/or marking (16), at least the surface (12) of the round stock (10) consisting of a metallic material, in particular of chromium or steel, for example of hardened steel, chromium-plated steel or stainless steel. In order to improve said method such that disadvantages and shortcomings are avoided, the method comprises the following steps: placing on the surface (12) at least one cover (20) which is adapted to the shape of the surface (12) and in particular has the inscription and/or marking (16), such that the region to be provided with the inscription and/or marking (16) is not covered by the cover (20), - exposing the round stock (10) to a first electrolyte (30) together with the cover (20), material being removed from the surface (12) by means of said electrolyte in the region to be provided with the inscription and/or the marking (16) while producing recesses (14), and - exposing the round stock (10) together with the cover (20) and the recesses (14) not covered by the cover (20) to a second electrolyte (32) by means of which the recesses (14) are filled to produce the inscription and/or marking (16) which differs from the surface (12) optically, in particular with respect to color. The present invention also relates to round stock (10) which is manufactured from a metallic material, said round stock being provided with a correspondingly produced inscription and/or marking (16).
