Abstract (en)
[origin: CN105097357A] A method of manufacturing a magnetic part (15, 17) of a differential relay (5) with high sensitivity comprises performing a surface treatment step of shot peening on at least one portion of a surface of the magnetic piece (15 , 17). The surface treatment step of shot peening comprises projecting pressure microbeads on the surface portion.
Abstract (fr)
Ce procédé de fabrication d'une pièce magnétique (15, 17) d'un relais différentiel (5) à haute sensibilité comprend une étape de traitement de surface par microbillage d'au moins une portion d'une surface de ladite pièce magnétique (15, 17). L'étape de traitement de surface par microbillage comporte une projection de microbilles sous pression sur ladite portion de surface.
