Abstract
Rotary graphite anode for use in X-ray tubes comprising a basic body consisting of graphite and a high melting alloy and having a tungsten alloy focal track. The basic body is secured to a graphite substrate. The graphite substrate is coated by a layer of carbon formed by decomposition of hydrocarbon gases in an activated d.c. voltage discharge.
