Abstract: A rotary anode comprising a basic body of carbon whose surface is provided with a pyrolytic graphite coating having a crystallographic layer structure. A metallic layer of high-melting temperature, in which X-rays are generated during operation in an X-ray tube, is provided on the body. The metallic layer and the pyrolytic graphite coating have a common contact face which cuts through the crystallographic layers in the pyrolytic graphite. Heat developed in the metallic layer is discharged through the face into the pyrolytic graphite layers.

Abstract: A preferred process for producing coated isotropic graphite members comprises: A. HEAT TREATING THE ISOTROPIC GRAPHITE MEMBER TO A TEMPERATURE FROM ABOUT 1700*C to 2400*C in a halogen atmosphere comprising chlorine or fluorine to reduce the impurity ash content to the range of the order to 2 to 10 ppm, B. MACHINING THE HEAT TREATED ISOTROPIC GRAPHITE MEMBER TO A PREDETERMINED SHAPE AND SURFACE CONDITION, C. ULTRASONICALLY CLEANING THE MACHINED GRAPHITE BODY IN A LIQUID CLEANING FLUID TO REMOVE LOOSE SURFACE PARTICLES, D. DEPOSITING A LAYER OF SILICON ON THE CLEAN GRAPHITE BODY BY A GAS PHASE REACTION AT A TEMPERATURE ABOVE 1000*C but below the melting point of silicon, E. HEATING THE GRAPHITE MEMBER WITH THE APPLIED LAYER OF SILICON TO A TEMPERATURE TO CAUSE THE SILICON TO MELT AND PENETRATE THE PORES OF THE GRAPHITE AND CAUSE THE SILICON TO REACT COMPLETELY IN SITU WITH THE GRAPHITE TO FORM A LAYER OF SILICON CARBIDE PENETRATING TO A DEPTH OF AT LEAST ABOUT 5 MILS, AND F. DEPOSITING BY A GAS PHASE REACTION A SEALING LAYER OF SILICON CARBIDE OVER THE UNDERLYING, PREVIOUSLY REACTED SILICON CARBIDE LAYER.
