METHOD OF PRELIMINARY WORKING ALUMINIUM ALLOYS Russian patent published in 1995 - IPC

Abstract SU 1823533 A1

FIELD: instrument making, machine engineering. SUBSTANCE: before galvanotreatment articles made of silumins were worked with high-frequency plasma at the following parameters: ion temperature is 300-400 K, azimuthal component of magnetic field intensity is 100-150 A/m, axial component of magnetic field intensity is 20-40 A/m, electron gas temperature is (5·10⁴- 05·10⁵K), charged particle concentration is 10⁹- 10¹⁰ U/cub.cm, plasma-forming gas flow rate is 100-150 m/s. EFFECT: improved method of working. 1 tbl
