Nā ʻano a me nā ʻano hana o ka holo ʻana o Arc Electron Flow

1.Characteristics o ka arc māmā electron kahe

ʻOi aku ka kiʻekiʻe o ke kahe o ka electron, kahe ion, a me nā mana kūʻokoʻa kiʻekiʻe i loko o ka plasma arc i hana ʻia e ka arc discharge ma mua o ka hoʻokuʻu ʻana.Nui aʻe nā kinoea a me nā ion metala i hoʻoheheʻe ʻia, hauʻoli i nā mana kiʻekiʻe o ka ikehu, a me nā pūʻulu hana like ʻole i ka wahi uhi, kahi mea nui i ka hoʻomehana, hoʻomaʻemaʻe, a me ka uhi ʻana i nā pae o ke kaʻina hana.ʻOkoʻa ke ʻano hana o ke kahe electron arc mai ka ion beam.No ka holo ʻana o nā electrons arc i ka anode, ua kuhikuhi ʻia ke kahe electron arc ma nā wahi a pau i hoʻopili ʻia ka electrode maikaʻi o ka mana arc, a hiki i ka anode ke lilo i mea hana, anode kōkua, crucible, etc.

2.Method o ka hana ʻana i ke kahe electron arc

(1) Hoʻokumu ke kumu kinoea i ke kahe electron arc: ʻo ke arc o kēia manawa o ka hollow cathode arc discharge a me ka hoʻokuʻu ʻana i ka uea wela hiki ke hiki i kahi 200A, a ʻo ka volta arc he 50-70V.

(2) Hoʻokumu ke kumu paʻa i ke kahe electron arc: kumu cathode arc, me ke kumu arc liʻiliʻi, cylindrical arc source, rectangular plane arc arc source, etc. ʻO ka arc au o kēlā me kēia cathode arc source discharge he 80-200A, a ʻo ka volta arc. 18-25V.

Hiki i ke kahe electron arc kiʻekiʻe a me ka haʻahaʻa haʻahaʻa i loko o nā ʻano plasma hoʻokuʻu arc ke hoʻoulu i ka ionization collision ikaika me ke kinoea a me nā mea kiʻiʻoniʻoni metala, e loaʻa ana i nā ion kinoea, nā ion metala, a me nā ʻano mana ikaika kiʻekiʻe a me nā hui, a laila e hoʻomaikaʻi ai. ka hana holoʻokoʻa o nā ion papa kiʻiʻoniʻoni.
