Makhalidwe ndi Njira Zoberekera za Arc Electron Flow

1.Makhalidwe a arc light electron flow

Kuchuluka kwa ma electron, kutuluka kwa ion, ndi maatomu osalowerera ndale mu arc plasma opangidwa ndi arc discharge ndi apamwamba kwambiri kuposa kutuluka kwa kuwala. Pali ma ion a gasi ndi ma ionized zitsulo, ma atomu amphamvu kwambiri, ndi magulu osiyanasiyana ogwira ntchito m'malo opaka, omwe amagwira ntchito yofunika kwambiri pakuwotcha, kuyeretsa, ndi kuyatsa magawo opaka. Mawonekedwe a arc electron otaya ndi osiyana ndi a ion mtengo, osati zonse zomwe zimasintha kukhala "mtengo", koma makamaka mu chikhalidwe chosiyana, choncho amatchedwa arc electron flow. Chifukwa ma elekitironi a arc amathamangira ku anode, kutuluka kwa ma elekitironi a arc kumayendetsedwa kulikonse komwe ma elekitirodi abwino amagetsi a arc amalumikizidwa, ndipo anode imatha kukhala chogwirira ntchito, anode wothandizira, crucible, ndi zina zambiri.

2.Njira yopangira ma arc electron flow

(1) The gasi gwero amapanga arc elekitironi otaya: arc panopa za dzenje cathode arc kumaliseche ndi otentha waya arc kutulutsa akhoza kufika pafupifupi 200A, ndi arc voteji ndi 50-70V.

(2) gwero lolimba amapanga arc elekitironi otaya: cathode arc gwero, kuphatikizapo yaing'ono arc gwero, cylindrical ozungulira gwero, amakona anayi ndege lalikulu arc gwero, etc. The arc panopa aliyense cathode Arc gwero kumaliseche ndi 80-200A, ndi arc voteji ndi 18-25V.

The mkulu-kachulukidwe ndi otsika mphamvu arc elekitironi otaya mitundu iwiri ya arc kumaliseche plasmas akhoza kupanga kwambiri kugunda ionization ndi mpweya ndi zitsulo maatomu filimu, kupeza ayoni mpweya, ayoni zitsulo, ndi osiyanasiyana mkulu-mphamvu yogwira maatomu ndi magulu, potero kuwongolera ntchito yonse ya ayoni wosanjikiza filimu.
