Abstract (en)
[origin: EP0168736A2] 1. A rotary X-ray anode having a ring-shaped focal track area comprised of a basic body (1), with or without a separate layer of the focal track area, made of high-melting metals and/or their alloys and a coating (2) made of high-melting compounds, said coating (2) applied to at least partial zones of said rotary X-ray anode and covering said focal track area, characterized in, that the thermal emissive coating (2) having a thickness in the range of 0.1 mu m and 2 mu m, whereby the source of the X-rays is remaining predominantly within the material of the focal track beneath the coating (2).
