Cathodes cathode - Import export

Tungsten and tungsten alloy electrodes are used to produce the arc in high-intensity discharge lamps. Tungsten electrodes from Plansee excel due to their outstanding physical and mechanical properties: a high melting point, low vapor pressure, low thermal expansion, good thermal conductivity and a low electron work function. Plansee supplies anodes, cathodes and support rods. With special alloy additives, Plansee improves the high-temperature dimensional stability, electron work function, formability, machinability and thermal conductivity of the material. For cathodes, aluminium-potassium silicate (AKS) or lanthanum oxide-doped tungsten is available. A new addition to the range: WLZ, a tungsten material doped with lanthanum and zirconium oxide. WLZ is the non-radioactive alternative to thorium-doped materials.

Plansee produces material for wear-resistant coatings, adhesive layers, decorative or DLC coatings. Offering compositions tailored for advanced hard coatings with optimized mechanical and tribological properties. Further topics that might be addressed are: enhancing of thermal and chemical stability, adding of functional properties like self-lubrication, self-hardening and self-healing. To adjust the coating characteristics to the dedicated application, Plansee offers its scientific expertise in alloying of targets and cathodes with elements that influence the coating properties as follows: Grain size and morphology, Hardness adaption, High temperature oxidation resistance, Friction coefficient, Thermal stability, Thermal conductivity, Electrical conductivity, Antibacterial properties, Color effects. Offered sputtering targets and arcing cathodes: Titanium-Aluminum Aluminum-Chromium Chromium Titanium-silicon Titanium Zirconium Tungsten carbide Titanium-diboride
