Abstract
A method of bonding a metallic target layer and a graphite disk to provide a composite rotating X-ray tube target wherein a high vapor pressure metal is placed between the target layer and the graphite disk and the vapor pressure of the joint is controlled. The vapor pressure is controlled by limiting the thickness of the joint and thereby causing the metallic character of the braze joint in this region to be altered. In a preferred manner, this is effected by interfitting projecting and recessed portions in the graphite disk and metallic target layer. The preferred high vapor pressure metal is titanium. A composite X-ray tube target is produced having a high remelt temperature and thus capable of being employed in X-ray tubes having more aggressive protocols.
