Properties

• alkaline zinc/nickel process of the third generation with superior throwing power and lower temperature sensitivity than regular processes
• carbonate and sulfate doesn't need to be frozen out
• produces Zn/Ni alloy deposits containing 12 to 14 % Ni
• produces alloy layers with a very uniform composition in the current density range from 0.1 to 3 A/dm2
• produces a grain refined, bright and homogenous surface appearance
• because of the third generation additives, the layer is very ductile, and exhibits no embrittlement, even in several different tests
• non cyanide alkaline process with high current efficiency (50–60 %)

General Advantages of Zinc/Nickel-Layers

Compared to other layer-systems as zinc or Zn/Fe, Zn/Ni-layers offer the following advantages:

• highest cathodic corrosion protection for steel and iron parts
• high thermal power rating until 160 °C (320° F)
• no voluminous corrosion products compared with zinc-layers
• no contact corrosion with aluminium
• virtually no risk of hydrogen embrittlement
• resistant against all common hydraulic fluids
• the nickel-detachment of zinc/nickel-layers with 15 % Ni-content is comparable with the detachment of stainless steel
