  • Method for pre-treating stainless steel substrates before soldering using nanocrystalline solder foils
    Patent number: 12220758
    Abstract: A soldered product comprising a first component soldered to a second component is provided. The first component comprises a stainless steel substrate, an adhesion promoter layer made of nickel deposited on at least one joining surface of the stainless steel substrate; and a tin layer deposited on the adhesion promoter layer. The tin layer has a layer thickness in the range of 10-30 ?m. The second component is typically a rare earth magnet.

  • Method for pre-treating stainless steel substrates before soldering using nanocrystalline solder foils
    Patent number: 11383315
    Abstract: A method for plating a stainless steel substrate is provided. According to one embodiment, the method comprises sandblasting at least one joint surface of a stainless steel substrate and treating the joint surface of the stainless steel substrate with an aqueous solution (acid bath) which contains sulfuric acid, nitric acid and hydrofluoric acid. The stainless steel substrate is then rinsed with hydrochloric acid. The method further includes galvanic deposition of a nickel plating on the joining surface of the stainless steel substrate and the subsequent deposition of a tin layer on the nickel-coated joining surface of the stainless steel substrate.

  • Method for the pretreatment of rare-earth magnets prior to soldering using nanocrystalline soldering foils and magnetic component
    Patent number: 11253951
    Abstract: A magnetic component with a rare-earth magnet is provided. The rare-earth magnet has a bronze coating that partially or entirely covers the surface of the rare-earth magnet. Further, the tin coating partially or entirely covers the bronze coating. A production process for the magnetic component as well as a soldering method for connecting the magnetic component with a substrate is also provided.
