carried out at the individual stages of industrial technological process, showed that the essential
problem in obtaining the galvanic coatings of satisfactory quality on the elements made of magnesium
alloys lies not only in the correct surface preparation, which is a well known phenomenon, but also in the
processes of later copper plating. The acid copper plating process, following the chemical nickel plating,
is very aggressive, which consequently leads to occurrence of pits in the base layer, in particular in the
element hollows such as holes and threads.
