ALKALINE ELECTROLYTE FOR ELECTRODEPOSITION OF ZINC-NICKEL COATINGS

摘要

FIELD: chemistry.SUBSTANCE: electrolyte contains, g/l: zinc oxide 12-15, caustic soda 100-120, sulfuric nickel 7-17, triethanolamine 40-60, hexamethylenediamine- N,N,N',N'- tetraacetic acid 0.5-2, diglycine 1-3, water to 1 l.EFFECT: increase of corrosion stability of zinc-nickel coatings, extension of range of working current densities, reduction of ecological load on purification of sewages by application of low-concentrated electrolytes.2 tbl, 4 ex
