Together with Manz Galvanotechnik, a modular and very flexible anodising plant was developed, set up at the Materials and Surface Engineering Department and put into operation in 2003. When designing this system, great importance was attached to a wide range of variation with regard to the process parameters temperature (0 to 50 °C), type of current (direct current, alternating current, pulsed current), amperage, voltage and frequency. Using special software, desired pulses can be freely drawn and complex electrical programme steps can be programmed. For new research projects in the field of surface refinement of light metals, the anodising plant is currently being considerably expanded. This will soon enable plasma-chemical coating processes (anof, spark discharge) to be realised. Likewise, a process bath is being developed that enables the incorporation of nanoparticles into the layer to improve functional properties.
