1.Izici zokugeleza kwe-electron ukukhanya kwe-arc
Ukuminyana kokugeleza kwe-electron, ukugeleza kwe-ion, nama-athomu angathathi hlangothi anamandla aphezulu ku-arc plasma akhiqizwa ukukhishwa kwe-arc kuphezulu kakhulu kunokukhishwa kokukhanya. Kukhona ama-ion e-gas amaningi nama-ion ionized ensimbi, ama-athomu anamandla amakhulu ajabulile, kanye namaqembu ahlukahlukene asebenzayo endaweni yokumboza, adlala indima ebalulekile ekushiseni, ekuhlanzeni, nasezigabeni zokumboza zenqubo yokumboza. Ifomu lesenzo lokugeleza kwe-electron ye-arc lihlukile kulelo le-ion beam, akuzona zonke ezihlanganayo zibe "i-beam", kodwa ikakhulukazi esimweni esihlukile, ngakho-ke kubizwa ngokuthi i-arc electron flow. Ngenxa yokuthi ama-arc electron ageleza abheke ku-anode, ukugeleza kwe-electron ye-arc kuqondiswa nomaphi lapho kuxhunywe khona i-electrode ephozithivu ye-arc power supply, futhi i-anode ingaba i-workpiece, i-anode eyisizayo, i-crucible, njll.
2.Indlela yokukhiqiza ukugeleza kwe-arc electron
(1) Umthombo wegesi ukhiqiza ukugeleza kwe-arc electron: i-arc yamanje yokukhishwa kwe-arc ye-cathode engenalutho kanye nokukhishwa kwe-arc yocingo olushisayo kungafinyelela cishe ku-200A, futhi i-arc voltage ingu-50-70V.
(2) Umthombo oqinile ukhiqiza ukugeleza kwe-arc electron: umthombo we-arc cathode, ohlanganisa umthombo we-arc omncane, umthombo we-arc cylindrical, indiza engunxande umthombo omkhulu we-arc, njll. I-arc yamanje yokukhishwa komthombo we-cathode arc ngayinye yi-80-200A, futhi i-arc voltage yi-18-25V.
Ukugeleza kwe-electron ye-arc enobukhulu obukhulu kanye nephansi kwamandla ezinhlotsheni ezimbili ze-arc discharge plasma kungenza i-ionization enamandla yokungqubuzana ngegesi ne-athomu yefilimu yensimbi, ithole ama-ion amaningi egesi, ama-ion ensimbi, nama-athomu namaqembu asebenzayo anamandla aphezulu, ngaleyo ndlela kuthuthukiswe umsebenzi wonke we-ion layer yefilimu.
