1. Hunhu hwekuyerera kwemaerekitironi echiedza chearc
Kuwanda kwemaerekitironi, kufamba kwemaion, uye maatomu asina simba rakawanda muplasma yearc inogadzirwa nekubuda kwearc kwakakwira zvikuru kupfuura kubuda kwechiedza. Kune maion akawanda egasi uye maion esimbi ane ionized, maatomu ane simba rakawanda, uye mapoka akasiyana-siyana anoshanda munzvimbo yekuputira, ayo anoita basa rakakosha muzvikamu zvekudziya, kuchenesa, uye kuputira kwemaitiro ekuputira. Chimiro chekushanda kwekuyerera kwemaerekitironi earc chakasiyana neche ion beam, kwete ese anoungana kuita "danda", asi kazhinji ari mumamiriro akasiyana, saka anonzi arc electron flow. Nekuti maerekitironi earc anoyerera akananga kune anode, kufamba kwemaerekitironi earc kunotungamirwa chero kupi positive electrode yesimba rearc yakabatana, uye anode inogona kuva workpiece, assistant anode, crucible, nezvimwewo.
2. Nzira yekugadzira arc electron flow
(1) Manyuko egasi anogadzira kuyerera kwemaerekitironi e arc: simba re arc rekubuda kwe cathode arc rakavhurika uye rinobuda netambo inopisa rinogona kusvika pa200A, uye voltage ye arc iri 50-70V.
(2) Soko rakasimba rinoburitsa arc electron flow: cathode arc source, kusanganisira small arc source, cylindrical arc source, rectangular plane large arc source, nezvimwewo. Arc current ye cathode arc source discharge yega yega i80-200A, uye arc voltage i18-25V.
Kuyerera kwemaerekitironi e arc ane density yakakura uye simba shoma mumhando mbiri dze arc discharge plasma kunogona kugadzira ionization yakasimba neatomu dzegasi nefirimu resimbi, zvichiwana ma ioni egasi akawanda, ma ioni esimbi, uye maatomu akasiyana-siyana ane simba guru uye mapoka, nokudaro zvichivandudza mashandiro ese ema ioni efirimu.
