Mazurczak: Cooling the black chrome process more efficiently

Thanks to its more compact size and improved heat transfer, an efficient titanium plate heat exchanger has made it possible to keep the black chrome process stable while reducing the bath volume by 25 percent.

Electrolytes require a certain working temperature, which can be exceeded during continuous operation due to the generation of Joule heat, heat input from the ambient temperature or exothermic reactions. In coating processes with high current densities, a high thermal output is converted into Joule heat in the bath. This heat input must be cooled continuously and reliably, and space-saving and energy-efficient heat exchangers can effectively support the cooling of process baths in electroplating.
