Latest Patents
Henriet's latest inventions focus on advanced pickling processes for stainless steel products. One notable patent describes a method for acid pickling that utilizes a bath with specific chemical compositions, including hydrofluoric acid (HF) at concentrations greater than 10 g/l and dissolved ferric iron (Fe³⁺) at more than 15 g/l. This method monitors and maintains the redox potential between +100 mV and +350 mV, allowing for oxidation to maintain the desired conditions. This innovative process not only streamlines the picking operation but also mitigates the environmental pollution typically associated with nitric acid.
Another patent proposes a pickling process in an acid bath containing an oxidant to accelerate pickling kinetics. It focuses on forming peroxygenated derivatives of titanium or its homologs that ionize the metal to a higher valency. This controlled process minimizes oxidizing agent use, ensuring the oxidation-reduction potential remains below the passivation potential of the metallic product.
