With the strongly acidic alloy electrolyte PLATUNA®-Alloy RU, smooth, shiny and crack-free platinum-ruthenium coatings can be deposited up to a layer thickness of 0.5 μm. The deposited coatings are characterized by brilliant gloss and, in contrast to conventional platinum coatings, do not exhibit a yellow tint.
The advantage of the electrolyte is mainly the cost saving due to the ruthenium content. This is because ruthenium is still the cheapest metal among the platinum group metals. Furthermore, the electrolyte has a low sulfuric acid content and is therefore less aggressive to the coating substrate. The deposition rate is independent of the current density, which leads to an optimum layer thickness distribution. No precipitation occurs and the platinum concentrate does not have to be stored in the refrigerator.
