In the field of strip steel coating for the car manufacture two conventional coating processes with full-fledged techniques are widely used in practice that give an acceptable quality-to-cost ratio - the hot dipping and the electro galvanizing. But due to a many ecological factors, the Physical Vapor Deposition (PVD) technique comes into play as another alternative for various reasons: A longer service life of the vehicles inevitably calls for enhanced corrosion protection of the car-body sheets used, coating should take place at an energy expenditure that has to be kept as low as possible, and the coating technique shall not result in questionable waste products that are likely to cause environmental pollution. Here the introduction of the PVD technique seems to be very promising for solving all these problems to full satisfaction. At the end of the 60s, and in the early 70s, this coating technique was already tested as an alternative to electroplating in order to substitute tin-plate. But this development was stopped due to various reasons. Since the mid-80s, plants for large-scale pilot operation were installed again in the Far East and recently also in Europe.
