| titleOfInvention | COMPOSITION FOR PRODUCING ELECTRIC INSULATION COATING ON TAPES OF AMORPHIC AND NANOCRYSTALLINE ALLOYS, METHOD FOR PREPARING IT AND METHOD FOR PRODUCING FROM IT COATING |
| abstract | 1. The composition for producing an electrical insulating coating on tapes of amorphous or nanocrystalline alloys containing phosphorus oxide and water, characterized in that it additionally contains zinc oxide and lithium carbonate in the following ratio, wt.%: Phosphorus Oxide - 24.5 - 28.0 Zinc Oxide - 11 - 12 Lithium carbonate - 9.5 - 10.0 Water - Else 2. A method of preparing a composition for an electrical insulating coating on tapes of amorphous or nanocrystalline alloys by mixing the starting components, characterized in that zinc oxide is added to phosphoric acid first, after it is completely dissolved in portions with vigorous stirring, lithium carbonate is added, after the cessation of carbon dioxide evolution, the mixture is kept for 8 to 10 hours, and then water is added until a density of 1.25 - 1.33 g / cm 3 is obtained.n n n 3. A method of producing an electrical insulating coating on tapes of amorphous and nanocrystalline alloys, comprising applying a composition containing phosphorus oxide and water to a surface to be treated, heat treatment in air and subsequent annealing, characterized in that a composition is added that additionally contains zinc oxide and lithium carbonate, heat treatment carried out in a gradient mode from 25 to 250 - 320 o With a tape speed of 0.3 - 0.4 m / min, and annealing is carried out at a crystallization temperature of the material or at 80 - 120 o C below this temperature.n n n 4. The method according to p. 3, characterized in that the annealing is carried out in the presence of a longitudinal constant magnetic field of more than 50 Ns of tape material. |
