摘要： In order to improve the adhesion of a magnetic steel sheet with no film of an inorganic material on the surface, in particular to a tension-imparted insulating film, an anodic treatment is executed in an aqueous solution of a silicate prior to forming the insulating film. Thus, a thin silicic film having a good adhesion to the insulating film is firmly formed on the surface of the surface of the steel sheet. This makes it possible to intimately and favorably form a tension-imparting insulating film on a grain oriented magnetic steel sheet to lower the iron loss of the grain oriented magnetic steel sheet. Even for an insulating film on a magnetic steel sheet which is not of the tension-imparting type, it is possible to improve the heat resistance of the film and to improve the insulating properties since the thickness of the film can be increased.

摘要： A tin-plating or aluminum-plating surface treated steel material with excellent corrosion resistance containing an intermetallic compound composed of one or more Group IIa (alkaline earth metal) elements and one or more Group IVb elements in a tin-based plating layer or aluminum-based plating layer on the surface of a steel material. For a tin-based plating layer, the long diameter of the intermetallic compound massive bodies is 1 µm or greater and the short diameter/long diameter ratio is at least 0.4. For an aluminum-based plating layer, the long diameter of the intermetallic compound massive bodies is 10 µm or greater and the short diameter/long diameter ratio is at least 0.4.

摘要： In order to improve the adhesion property of an electrical steel sheet with no film of inorganic mineral matter on its surface, especially with respect to a tension-imparting insulating film, anodic electrolysis in an aqueous solution of silicate is carried out before insulating film formation to form a silicic film excellent in adhesion property with respect to the insulating film in a thin and strongly attached condition on the steel sheet surface. By this, a tension-imparting insulating film can be formed on a grain-oriented electrical steel sheet with excellent adhesion property to reduce the iron loss of the oriented electrical steel sheet. Also in the case of an insulating film that is not of the tension-imparting type, enhancement of film heat resistance and improvement of insulating property by increasing a film thickness are possible.
