  • Method for making a light weight high performance target
    Publication number: 20060151578
    Abstract: An x-ray anode for use in an x-ray tube is provided. The x-ray anode includes a substrate material, a target material, and one or more graded coefficient of thermal expansion material layers. The target material is coupled to the one or more graded coefficient of thermal expansion material layers and the graded coefficient of thermal expansion material layers are coupled to the substrate material. A method of making the x-ray anode is also provided.
    Type: Application

  • Method for making a rotating anode with an integral shaft
    Patent number: 5592525
    Abstract: A method for making a rotating X-ray tube provides a rotating anode having an integral stem. Initially, a cathode which emits electrons is provided. Next, a preheated anode target which radiates x-ray in response to bombardment by the electrons is provided. The method further comprises the steps of providing an anode stem and inertia welding the preheated anode target to the anode stem to form a rotating anode with an integral stem.
