US 2016/0254115 A1 · ROTARY X-RAY ANODE AND PRODUCTION METHOD

Abstract

A rotary X-ray anode has a support body and a focal track formed on the support body. The support body and the focal track are produced as a composite by powder metallurgy. The support body is formed from molybdenum or a molybdenum-based alloy and the focal track is formed from tungsten or a tungsten-based alloy. Here, in the conclusively heat-treated rotary X-ray anode, at least one portion of the focal track is located in a non-recrystallized and/or in a partially recrystallized structure.

Dependent claims

A rotary X-ray anode, comprising:

a powder-metallurgically produced composite formed of a support body and a focal track on said support body;
said support body being formed of molybdenum or a molybdenum-based alloy;
said focal track being formed of a tungsten-rhenium alloy having a rhenium proportion in a range of 5-10% by weight;
and
wherein, in a conclusively heat-treated rotary X-ray anode, at least one portion of said focal track is present in a non-recrystallized or a partially recrystallized structure and having a hardness of ≧350 HV 30.
