Latest Patents

Fukushi's notable patent, titled "Electrolytic copper-plated R-T-B magnet and plating method thereof," outlines a unique approach to enhancing the performance of R-T-B magnets. These magnets, characterized by their rare-earth elements such as Y and the inclusion of iron (Fe) or cobalt (Co), feature an electrolytic copper-plating film. This film is tactically designed so that the ratio [I(200)/I(111)] of the X-ray diffraction peak intensity from the (200) to the (111) plane falls between 0.1 and 0.45. The innovative electrolytic copper plating method utilizes a solution rich in copper sulfate and chelating agents, ensuring a pH range adjusted between 10.5 and 13.5 without any reducing agents. This advancement not only optimizes the magnet's electrical properties but also enhances its durability and performance.
