More efficient manufacturing of ceramic coatings: no problem thanks to PLANSEE's new cathode fixturing system.
Hard and extremely durable: ceramic coatings make an ideal protective layer for tools and components. To date, ceramic and brittle materials could only be deposited by means of the reactive magnetron sputtering method, in part because of the lack of an appropriate fixing system for arc evaporation. But now PLANSEE has developed a suitable fixing system for ceramic and brittle composite materials. Using an integrated carrier plate and a cathode ring, tungsten carbide, chromium-silicon, titanium-diboride and titanium-chromium, among other materials, can now be used as arc-cathodes.
(firmenpresse) - When it comes to coating tools, arc evaporation is generally a more efficient method than magnetron sputtering. A threaded hole in the arc cathode usually fixes the coating material in the coating system. Ceramic and brittle composite materials are unsuitable for this type of mechanical machining, which they would not withstand intact. Therefore until recently tungsten carbide, for example, could only be applied to the various substrates by means of the magnetron sputtering method.
PLANSEE has now developed a new fixing system facilitating the use of ceramic and brittle composite materials as cathodes in arc evaporation. The system comprises an integrated carrier plate and a cathode ring. As the various cathode materials have different thermal expansion coefficients, molybdenum is also available as an alternative to copper as a material for the carrier plate. The cathode ring made from molybdenum or ceramic materials encloses the coating material and ensures that the arc remains on the cathode material during the coating process.
The new mounting system is suitable for arc cathodes made of tungsten-carbide, chromium-silicon, titanium-diboride and titanium-chromium, among other materials. It is particularly robust and can be reused multiple times in many cases.
