Schlötter’s SLOTOLOY ZN VX technology was awarded the Innovation Prize of the state of Baden-Württemberg in 2018. Zinc-Nickel SLOTOLOY ZN 210 VX was developed for barrel applications and deposits zinc-nickel coatings (12-15% nickel).Particularly noteworthy are the consistently high current efficiency and the high deposition rate. Degradation products have been significantly reduced, which means that regular dilution of the electrolyte is not necessary. The required bath voltage for SLOTOLOY ZN 210 VX is lower than for bright nickel-plated steel anodes and significantly lower than for comparable membrane processes. This results not only in lower current quantities for depositing the zinc-nickel alloy, but also in lower energy consumption for cooling and, as a result, a favourable CO2 balance.
