Chapter 6 x-ray production Flashcards | Quizlet

A process is disclosed for the production of a tungsten carbide-activated electrode, particularly an electrode which is utilizable as a cathode, and which consists of an electrically-conductive substrate with an active surface layer of tungsten carbide. The tungsten carbide is adhesively bonded through chemical reaction to the surface of a substrate which is constituted of graphite or a ...

The cathode is the negative terminal of an x-ray tube. It is a tungsten filament and when current flows through it, the filament is heated and emits its surface electrons by a process called thermionic emission. Kilovoltage. High voltage, in the kilovolt range (1000 volts), is applied between the cathode and anode.

The Manufacturing Process of a Tungsten Halogen Light Bulb

Contaminated cemented carbide scrap, turnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores. If present, cobalt, tantalum and niobium are recovered in separate processing lines. Other tungsten containing scrap and residues might require a modified process.

The X-ray spectrum. As a result of characteristic and bremsstrahlung radiation generation a spectrum of X-ray energy is produced within the X-ray beam. This spectrum can be manipulated by changing the X-ray tube current or voltage settings, or by adding filters to select out low energy X-rays.

The Tungsten Carbide Manufacturing Process

The heat is sufficient enough to be able to slightly melt the tungsten carbide and this results in it being turned into a cement style material. There are special names given to tungsten carbide that has been made in this fashion with hard metal or Carboloy being used. This is not the only process of making tungsten carbide though.
