摘要： PURPOSE:To maintain excellent magnetic property for a long period by covering the surface of an RE-B-Fe sintered rare earth magnet or an RE-TM-B hot processed rare earth magnet with the organic layer by an anion type electrodeposition device. CONSTITUTION:For a high corrosion-resistant metallic magnet, the surface of a rare earth magnet is covered with an organic coating layer by an anion type electrodeposition device. By this method, the organic coating layer forming material is adsorbed electrically on the surface of the magnet and forms a film, so the adhesion is increased remarkably as compared with an ordinary immersing method, a spray method, etc. It has a thickness uniform all over the surface, and there is no fear of local coating defects such as a pinhole, etc. Hereby, excellent magnetic property can be gotten for a long time.

摘要： PURPOSE:To aim at the promotion of high speed treatment for descaling by giving mechanical grinding and electric load simultaneously to steel with an oxidized scale on the surface in an electrolytic solution. CONSTITUTION:An electrolyte 19 is filled up in a tank 18 in which a mechanical grinding means 20 and an electrode 21 are set up. A hot rolled steel sheet 17 is led into this electrolyte 19 by a roller 25. One terminal 22 out of a voltage generator 23 is connected to the electrode 21, and the other terminal 24 is connected to the steel sheet subjected to a descaling process, thus an electrolytic cell is constituted of the electrolyte 19, the steel sheet 17 and the electrode. Accordingly, the steel sheet 17 being lend into the electrolyte as traveling is given mechanical grinding and electrolytic load in the electrolyte 19 simultaneously, so that any pickling by hydrochloric acid and sulfuric acid falls into disuse and, what is more, descaling time is reducible, thus it can be made into high speed promotion.
