The present disclosure relates to a brazing structure. The brazing structure may comprise a first portion and a second portion. At least one of the first portion or the second portion may include a connection-reinforcing surface. The connection-reinforcing surface may include a groove region and a filler placement region. The filler placement region may be configured to hold a filler material in solid state before brazing. The groove region may include a plurality of grooves where the filler material flows into after being melted. The first portion and the second portion may be connected by a braze joint formed by the filler material.

At least some example embodiments relate to an X-ray rotating anode, an X-ray tube and an X-ray emitter. The inventive X-ray rotating anode has a carrier including at least one of molybdenum or a molybdenum alloy; a first focal path on the carrier; and a second focal path on the carrier, wherein at least one of the first focal path or the second focal path comprises at least one of tungsten or rhenium, at least one of the first focal path or the second focal path are embodied on the carrier via a vacuum plasma spraying (VPS) coating method, and the first focal path and the second focal path are distanced from one another via an intermediate section in the carrier between the first focal path and the second focal path.
