Anode disk element with refractory interlayer and VPS focal track

摘要

An anode (30) is formed by building a carbon, such as a carbon reinforced carbon composite, or other ceramic substrate (50). A ductile, refractory metal is electroplated on the ceramic substrate to form a refractory metal carbide layer (52) and a ductile refractory metal layer (54), at least on a focal track portion (36). A high-Z refractory metal is vacuum plasma sprayed on the ductile refractory metal layer to form a vacuum plasma sprayed high-Z refractory metal layer (56), at least on the focal track portion.
