ZINC ALLOY
Certain soils, especially those that are inorganic, either are removed in acid cleaners or are dissolved in the acids, or both. As distinct from pickling and derusting, the main emphasis is on cleaning effect, and solutions are therefore more mildly acidic. It is not the object of acid cleaners to remove heavy grease or oil deposits, such as removed by alkaline solutions or solvents, but rather to remove light grease, oxide films and similar inorganic films. They are generally used in final or near final preparation of metals prior to plating.
ZN FE 992 PROCESS FOR ZINC/IRON ALLOY PLATING FROM AN ALKALINE CYANIDE-FREE BATH
Description
ZN FE 992 provides a bright, ductile electro-deposited zinc-iron alloy containing from 0.1% to 0.8% iron that is evenly distributed at low, mid and high current densities. ZN FE 992 alloy deposits provide greatly enhanced corrosion resistance compared to zinc plate when properly chromated.
ZN FE 992 process operates at a zinc concentration of 1 – 2.5 oz./gal (7.5 – 18.75 g/l) allowing more flexibility when maintaining the range of zinc levels. ZN FE 992 process does not require separate rectifiers or anodes for replenishment of iron in the bath.
ZN FE 992 deposits accept a non-silver black chromate as well as conventional yellow, clear, and silver-black chromates.
KM ZN NI 500
Description
KM ZN NI 500 provides a bright, ductile electro-deposited zinc-nickel alloy containing from 12% to 15% nickel that is evenly distributed at low, mid and high current densities. KM ZN NI 500 alloy deposits provide greatly enhanced corrosion resistance compared to zinc plate when properly chromate.
KM ZN NI 500 process operates at a zinc concentration of 6.0 – 12 g/l allowing more flexibility when maintaining the range of zinc levels.
KM ZN NI 500 process does not require separate rectifiers or anodes for replenishment of nickel in the bath. KM ZN NI 500 deposits accept conventional and high corrosion trivalent passivate technologies.
