Rotating anode for X-ray tubes

摘要

There is disclosed a rotating anode for use in X-ray tubes having a basic member made of a carbonaceous molybdenum alloy, such as TZM, and a focal path, that is a cathode path, of tungsten or a tungsten alloy, the surface of the basic member outside the focal path being coated at least partially with one or more oxides or a mixture of one or more metals and one or more oxides and having a 10 to 200 mu m thick layer of molybdenum and/or tungsten disposed between the surface of the basic member and the coating thereon of oxides or mixture of metal and oxides.
