Zinc-nickel coatings are widely used due to their excellent anti-corrosion properties. It is crucial for the quality of these and other metallic coatings that the composition of the galvanic bath remains within a narrow tolerance range. This is the only way to achieve the desired coating properties. Electroplating baths are subject to process-related fluctuations, which can have a considerable influence on the deposition behavior and the resulting coating thickness. In order to better control the deposition process and avoid excessive waste, the bath solutions must be regularly monitored by analysing the solution as often as possible. In the case of an electroplating bath with a zinc-nickel solution, continuous monitoring is desirable. Inline measurement using X-ray fluorescence analysis is the ideal solution for efficient bath monitoring and control.
