    Abstract: The present invention relates to a method for providing a molybdenum-molybdenum or molybdenum alloy-molybdenum alloy brazing. In accordance with the invention this method comprises the following steps: —providing at least two parts (16, 22) made of molybdenum or a molybdenum alloy; —brazing together said two parts (16, 22) using a brazing material (26); and—providing a plasma-sprayed molybdenum of molybdenum alloy layer (28) at least on a portion of the brazing material (26) that would be accessible otherwise. Furthermore, the present invention is directed to a rotary-anode X-ray tube (14) which is equipped with a spiral groove bearing (12) comprising, as a first part (16), an axle blank (16) having a center bore (18) and being made of molybdenum or a molybdenum alloy and, as a second part (22), a cap (22) made of molybdenum or an molybdenum alloy, wherein, for closing one open axial end (24) of said axle blank (16), said axle blank (16) and said cap (22) are brazed together using the method in accordance with the invention.
