Substitution of galvanic processes using secondary plasma flame coating

In comparison with electroplating processes, the ion beam coating method has the advantage that neither poisonous wastewater nor acid or caustic vapors are generated. A high-performance ion source including the high-frequency generator required to excite the plasma was developed and tested to study secondary ion beam coatings. The results show that the coating rates of chrome are higher than those of electroplating coating rates. Moreover, the ion beam coating method can also be used to influence the structure of the separated layers to a much greater extent as well as prevent the forming of fringe crystals (detail information in German).
