For more than three decades, corrosion resistant layers for automotive light reflectors were deposited by PCVD (Plasma Chemical Vapour Deposition) using Hexamethyldisiloxane as a common source. This siloxane is easy to evaporate due to its high vapor pressure, it is available at an acceptable price, and the plasma polymers have all the properties required to fulfill the different specifications of car manufacturers and their suppliers throughout the world. Progress in the development of modern car lights leads to light sources with a higher light output, but smaller housings with an increasing temperature impact on the thermo-plastic materials. This is why the temperature resistance of corrosion resistant layers must be improved. Another ongoing target to cut coating costs is the reduction of process times. New siloxanes and their mixtures with gases are an approach to improve corrosion resistance and increase deposition rates. The paper reports first results obtained from a series of different production machines, including evaporation batch coaters, short-cycle sputter machines such as the DynaMet family, and the new PylonMet IV sputter system.
