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.
