<\/div>

Zinc-nickel plating is an environmentally and safer alternative to cadmium and can be used across a wide range of industries. It combines the sacrificial coating properties of zinc with the strength, ductility, and corrosion resistance of nickel \u2013 creating a surface finish that, in some cases, is superior to cadmium.<\/p>\n

The use of sacrificial, anodic coatings has become increasingly popular in the aerospace<\/span><\/a>, industrial<\/span><\/a> and automotive sectors due to its corrosion protection, wear resistance and ability to limit thermal stress.<\/p>\n

Why is zinc-nickel resistant to corrosion<\/h2>\n

Both ZnNi and Cadmium<\/a> are sacrificial coatings that will corrode before the substrate material, protecting it. That is why both coatings experience discoloration before red rust appears. In ZnNi the Zn continues to act as a sacrificial coating, but in addition the Ni is able to act as a barrier layer due to being more noble than the Zn and the underlying substrate. ZnNi coatings protect best when there is between 11-16% Ni with Zn balance.<\/p>\n
