Focal track structures for X-ray anodes and method of preparation thereof

摘要

An improved high performance x-ray tube having a rotating graphite anode therein and method of preparation thereof. The surface of a graphite anode body is oxidized in air for removing the surface damage caused during the machining of the anode body. The anode body is provided with a diffusion barrier layer of rhenium contiguously disposed on the substantially damage free surface of the anode body. An anode target layer is then deposited on top of the barrier layer.
