METHODS FOR PREPARING THE SURFACE OF ALUMINUM ALLOYS FOR ELECTROPLATING (review)
A review of modern scientific publications in the field of methods for preparing the surface of aluminum alloys for electroplating is presented. It is shown that the most widely used methods of preparation are: zinc treatment, high-porosity anodic oxidation and immersion nickel plating. A number of combined methods for preparing the surface of aluminum alloys for electroplating are given. Methods of direct application of electroplating coatings on aluminum and its alloys without the use of a sublayer, both by electrolytic and chemical methods, are considered.
