For hard and wear resistant coatings
PALLUNA® 4700 is a chloride-free, ammonia-reduced high-speed electrolyte for the deposition of a semi-bright to bright palladium-nickel alloy in reel-to-reel lines (selective dipping, jet plating, brush plating) and tabplaters.
Depending on the operating conditions, the electrolyte deposits alloy layers with approx. 80% of Pd. The alloy composition is largely independent of the current density.
The hard and wear-resistant layers are ductile, with low internal stresses and exhibit good corrosion resistance.
