ABSTRACT:
The invention relates to anodes for X-ray tubes and a method of producing same. Several layers are deposited one after another onto a substrate by means of chemical vapour deposition. The proposed combination of layers results in a proper bond to the substrate. The combination comprises a first layer of molybdenum or a molybdenum alloy; a second layer of a tungsten-molybdenum alloy and a third layer of tungsten or a tungsten alloy. The composition of the second layer varies over its thickness.
