RAY TUBE TARGETS FROM ONE WITH A HIGH SOLID oxide dispersion REINFORCED MOLYBDENUM ALLOY

摘要

is provided X-ray tube anode target substrate (28), consisting of a reinforced with an oxide dispersion molybdenum alloy, and its rear side with a graphite ring (20), having a structure (30) vertically projecting from the substrate and is fixed to a rotor, with a radially inner substrate portion (28 '), which is connected with the vertical structure and a connecting portion (36) having a radially outer substrate portion (28 "), and an annular focal track (18) on the front of the radially outer substrate portion is formed an X-ray emitting metal, the vertical structure of the front side of the substrate protrudes, and an average thickness of the radially inner substrate portion is smaller than the average thickness of the radially outer substrate portion, and radially outwardly to increase the thickness of the substrate in the direction along the connecting portion.
