DEVICE AND METHOD FOR ANODIZED OXIDATION OF AN ANODE ELEMENT FOR A CURVED X-RAY GRATING, SYSTEM FOR PRODUCING A CURVED X-RAY GRATING AND CURVED X-RAY GRATING

摘要

The present invention relates to a device for anodized oxidation of an anode element for a curved X-ray grating, the device (10) comprising: an anode element (12); a cathode element (14); an electrolytic medium (16); a conductor element (18); and a carrier element (20); wherein the anode element (12) comprises a first side (11) and a second side (13), wherein the second side (13) faces opposite to the first side (11); wherein the carrier element (20) comprises a curved surface section (21) that extends along a curvature around a center of curvature (30); wherein the carrier element (20) is configured to receive the second side (13) of the anode element (12) for attaching the conductor element (18) to the first side (11) of the anode element (12); wherein the curved surface section (21) is configured to receive the conductor element (18) after detaching the second side (13) of the anode element (12) from the carrier element (20); wherein the electrolytic medium (16) is configured to connect the anode element (12) and the cathode element (14); wherein the cathode element (14) in conjunction with the anode element (12) and the electrolyte medium (16) is configured to generate at least one group of electric field lines (26) that define a plane (31, 33, 35, 37, 39), wherein at least a straight extrapolation (32) of the group of electric field lines intersect the center of curvature, wherein the generation of the at least one group of electric field lines (26) results in an anodized oxidation of the anode element (12) on the curved surface section (21). The invention provides a device (10) that avoids the risk of damaging the grating structures and getting a low yield.
