Latest Patents
Dastolfo's latest patents include a groundbreaking process for low temperature electrolysis of metals in a chloride salt. This innovative method utilizes a low temperature salt bath for the electrolysis of metal oxides, producing the corresponding metal. The bath consists of a first salt, which is at least one fluoride salt, and a second salt, which is at least one chloride salt. The fluoride salt enhances the solubility of metal oxides in the molten salt bath, while the chloride salt lowers the bath's liquidus temperature. The preferred process involves using an anode made primarily of carbonaceous material, with an effective surface area that matches the projected surface area of the anode.
Another significant patent is for a milling solution and method that is substantially nitrate-free. This solution is designed for milling products of refractory metals, particularly titanium. It comprises hydrofluoric acid, a hydrogen inhibitor selected from a specific group, and a balance of water and impurities. The method disclosed allows for chemically milling, etching, and/or pickling metal products, such as titanium alloy forgings, using this innovative solution.
