METHOD OF MANUFACTURING ROTARY ANODES FOR USE IN X-RAY TUBE AND ROTARY ANODES MANUFACTURED BY SAID METHOD

摘要

A novel method of manufacturing a double-layer rotary anode for use in X-ray tubes, in which by means of a "high energy rate forming process" an anode portion mainly made of tungsten and a supporting portion mainly made of molybdenum are secured to each other by one stroke. The composition and the pretreatment of each of these portions may be chosen to the optimum with respect to the required properties such as mechanical strength and heat resistance, which properties are not adversely affected by this process of adhesion in contrast to the effect of known adhering techniques.
