  • Anisotropic permanent magnets
    Patent number: 4536230
    Abstract: A permanent magnet made of a rigid material, said magnet having, within its entire body or in a part thereof, an anisotropic magnetic structure wherein the axes of easy magnetization in the elementary magnet regions have a convergent orientation in the environment of at least one of magnet poles. The value of magnetic induction to be delivered by the magnet of the invention to an air gap, or other part of magnetic circuit is raised relative to conventional anisotropic permanent magnets made of the same materials.

  • Process for the electrolytic deposition of layers of nickel alloys
    Patent number: 4525248
    Abstract: A process of electrolytic deposition of layers of nickel alloys, especially nickel alloyed with molybdenum, with tungsten, and with phosphorus, from an electrolyte on the basis of sulphosalicylate. The object to be coated is degreased, rinsed with activation solution, for example with sulphosalicylic acid, is electrolytically activated with nickel (II) chloride solution, and coated in an electrolyte containing compounds of alloying elements, a halide, wetting agents, and a luster-forming admixture.

  • Electrolyte for cathodic deposition of nickel alloys with iron
    Patent number: 4372826
    Abstract: An electrolyte for the deposition of nickel alloys with iron in the range from 3 to 30% by weight of iron. This electrolyte is based on nickel(II)- and iron(II) sulphosalicylate, with an admixture of a halide, for example potassium iodide, further an admixture of a wetting agent, for example sodium laurylsulphate, and an admixture of a compound with a buffer effect, for example boric acid.
