Abstract
A composite target for an x-ray tube has a graphite substrate portion and a metal portion, the two portions being bonded together by platinum and platinum alloying materials. The preferred alloying materials are tungsten and nickel which act in conjunction with the platinum to improve the bond resulting in an x-ray tube having a longer life span.
