Abstract:
A method of making an x-ray tube target anode, which method comprisesproviding a dense body of tungsten (W) or molybdenum (Mo) metal suitable for serving as a target anode to create x-rays, providing a carbonaceous support body capable of withstanding high temperatures under vacuum conditions and having a surface complementary to a surface of said dense body, coating said complementary surface of said support body with a layer of a material containing a mixture of particulate Hf carbide or Zr carbide and particulate tungsten boride or molybdenum boride, and joining said dense body to said carbonaceous anode support by introducing a layer of elemental hafnium (Hf) or zirconium (Zr) between said complementary coated surface of said support body and said dense body, juxtaposing said complementary surfaces of said dense body and said support, and heating to a reaction-brazing temperature under vacuum or an inert atmosphere such that said dense body thereafter strongly adheres to said carbonaceous support body.
