Ọnọdụ maka mkpuchi cathode ion oghere

Ọnọdụ ndị a ka achọrọ ka ọkụ ọkụ cathode oghere dị:

1. A na-etinye egbe cathode oghere nke nke tantalum tube na mgbidi ụlọ mkpuchi ma nwee ike iji mee ka ọkụ eletrik na-ekpo ọkụ. N'ime dayameta nke ewepụghị tube bụ φ 6 ~ φ 15mm, na a mgbidi ọkpụrụkpụ nke 0.8-2mm.

1. Ọkụ ọkụ ahụ bụ nke arc na-amalite ọkụ ọkụ na arc na-edobe ike ọkụ n'otu aka ahụ. The voltaji nke arc pụtara ike ọkọnọ bụ 800-1000V, na arc pụtara ìhè ugbu a bụ 30-50A; The arc voltaji bụ 40-70V, na arc ugbu a bụ 80-300A.

Usoro mwepụ nke oghere cathode arc na-eso usoro ịtụgharị site na mwepu na-egbuke egbuke na-adịghị mma na mwepu arc na "volt ampere characteristic curve". Nke mbụ, a chọrọ ọkụ eletrik iji nye voltaji mmalite nke 800V iji mee ka ọkụ na-egbuke egbuke na tube tantalum. Argon ion dị elu dị elu n'ime tantalum tube bombard na-ekpo ọkụ na tube na okpomọkụ ebe electrons na-ekpo ọkụ na-emepụta, na-eme ka ọnụ ọgụgụ dị ukwuu nke electron plasma na-abawanye na mberede na-abawanye ugbu a nke oghere cathode arc. Mgbe ahụ, a na-achọkwa ọkụ ọkụ dị elu ugbu a iji nọgide na-agbapụta arc. Usoro nke ịtụgharị site na nkwụsị ọkụ na nkwụsị arc bụ akpaka, ya mere ọ dị mkpa ịhazi ọkụ eletrik nke nwere ike ịmepụta ma elu voltaji na elu ugbu a.

Ọ bụrụ na ihe abụọ a chọrọ na-lekwasị na otu ike isi iyi, nke abụọ mmepụta ọgwụgwụ nke ike transformer ga-emerụ na nnọọ oké wires n'ihi na ọtụtụ ntụgharị ka mmepụta elu voltaji na elu ugbu a, nke ga-abụ nnukwu olu ike isi iyi. Mgbe ọtụtụ afọ nke mmelite gasịrị, ọ ga-ekwe omume ịmekọrịta obere arc na-amalite ọkụ ọkụ na-arụ ọrụ arc na-arụ ọrụ. The arc na-amalite ike ọkọnọ na-eji obere wires na ifufe otutu ntụgharị, nke nwere ike mmepụta a elu voltaji nke 800V na-amụnye tantalum tubes na n'ịwa ìhè mwepu; Ọkụ ọkụ arc nwere ike iwepụta iri puku volt na narị amperes nke dị ugbu a site na ịgbanye waya siri ike na ntụgharị ole na ole iji jikwaa nkwụsi ike nke oghere cathode arc. N'ihi njikọ yiri nke abụọ ike ọkọnọ na tantalum tubes, n'oge usoro nke converting si abnormal glow mwepu na arc ikpughe, abụọ ike ọkọnọ ga-akpaghị aka jikọọ na ịgbanwe si elu voltaji na ala ugbu a na obere voltaji na elu ugbu a.

1. Ngwa ngwa dozie ọkwa agụụ. Oghere oghere maka mwepu ọkụ na tubes tantalum dị ihe dịka 100Pa, na usoro ihe nkiri echekwara n'okpuru ọnọdụ oghere dị ala bụ nke enweghị atụ. Ya mere, mgbe ịgbanye nkwụsị nke arc, ọ dị mkpa iji belata ikuku ikuku ozugbo wee gbanwee ọkwa oghere na 8 × 10-1 ~ 2Pa iji nweta nhazi ihe nkiri mbụ dị mma.

1. The workpiece turntable arụnyere na gburugburu mkpuchi ụlọ, na workpiece jikọọ na-adịghị mma okporo osisi nke ele mmadụ anya n'ihu ike ọkọnọ na agụụ ụlọ jikọọ mma osisi. N'ihi ịdị elu dị ugbu a nke oghere cathode arc, voltaji ele anya nke ion mkpuchi workpiece adịghị mkpa iru 1000V, na-abụkarị 50-200V.

5. Tọọ eriri electromagnetic na-elekwasị anya gburugburu Gan ida, na oghere electromagnetic nke a na-emepụta site n'itinye ugbu a na eriri igwe nwere ike ilekwasị anya n'okirikiri eletrọn dị n'etiti etiti metal ingot, na-abawanye njupụta ike nke electron eruba.
