PROTECTIVE QUALITIES OF ALTERNATELY LAYERED PLATES

The basic regularities of the corrosion-electrochemical behavior of al ternately layered electroplates (ALP) copper-nickel were investigated. It was established that the protective ability of ALPs in a NaCl solu tion is proportional to the number of the layer-pairs in a plate of th e same thickness. It enables one to apply coatings of a higher protect ive quality with the same consumption of metals, or to substantially r educe the use of expensive nonferrous metals, retaining the basic perf ormance of the protective coatings.
