Isikebhe esihlanzekile se-wolfram tungsten se-vacuum coating

Incazelo emfushane:

Isikebhe se-W1 esihlanzekile se-tungsten sivame ukusetshenziswa enqubweni yokuhlanganisa i-vacuum.Lezi zikebhe zenzelwe ukuqukatha kanye nokuthutha izinto ezifana nezinsimbi noma ezinye izinto ezinhlelweni zokuhwamuka kwevacuum.Indawo encibilikayo ye-tungsten ehlanzekile kanye ne-thermal conductivity enhle kakhulu iyenza ilungele lolu hlelo lokusebenza, njengoba ingamelana namazinga okushisa aphezulu futhi inikeze ukufudumeza okufanayo okudingekayo ukuze kuhwamulise into endaweni engenalutho.

Iyini indlela yokuhwamuka kwe-vacuum ye-metalization?

Ubuchwepheshe bokuhwamuka kwe-vacuum be-metallization buhilela ukufaka amafilimu amancane ensimbi kuma-substrates kusetshenziswa indawo yokukhipha umoya ephezulu kanye nenqubo yokubeka umhwamuko obonakalayo (PVD).Kulobu buchwepheshe, okokusebenza komthombo wensimbi, okufana ne-aluminium, igolide noma isiliva, kushiswa esikebheni esihwamukayo, kusenze sihwamuke bese sijiya ku-substrate ukuze kwakhe ifilimu yensimbi encane nefanayo.

Izinyathelo ezibandakanyeka kubuchwepheshe be-metalization vacuum evaporation ngokuvamile zifaka:

1. Ukulungiselela: Hlanza i-substrate ezokwenziwa insimbi futhi uyibeke ku-vacuum room.

2. Ukuhwamuka: Faka izinto eziwumthombo wensimbi esikebheni esihwamukayo, njengesikebhe se-tungsten, bese usishisisa ezingeni lokushisa elihwamukayo endaweni enomhwamuko ophezulu.Lapho insimbi ihwamuka, ihamba ngomugqa oqondile ku-substrate.

3. I-Deposition: Umhwamuko wensimbi uyajiya ku-substrate ukuze wakhe ifilimu elincanyana elinamathela phezulu.

4. Ukukhula kwefilimu: Inqubo yokubeka iyaqhubeka kuze kube yilapho kufinyelelwa khona ukujiya kwefilimu yensimbi oyifunayo.

5. Ukucutshungulwa okulandelayo: Ngemva kokwenziwa kwe-metallization, i-substrate ingase ibhekane nezinyathelo ezengeziwe zokucubungula, ezifana ne-anneal noma ukugcoba, ukuthuthukisa izakhiwo zefilimu yensimbi.

Ubuchwepheshe be-vacuum evaporation metallization busetshenziswa kabanzi ezimbonini ezifana ne-electronics, optics, kanye nezimoto, lapho amafilimu ensimbi asetshenziswa kuma-substrates ukuze kufezwe ama-conductive, acwebezelayo, noma ahlobisa.

Uyini umthombo wokuhwamuka kwevacuum?

Umthombo wokuhwamuka kwe-vacuum ezinqubweni zokufakwa kwefilimu elincanyana ngokuvamile uyindawo ephezulu yevacuum edalwe egumbini le-vacuum.Igumbi le-vacuum lifakwe ipompo ye-vacuum esusa umoya namanye amagesi ukuze kwakheke indawo enengcindezi ephansi.Amaphampu evacuum angaba izinhlobo ezihlukahlukene, njengamaphampu e-rotary vane, amaphampu okusabalalisa noma amaphampu e-turbomolecular, kuye ngezidingo ezithile zenqubo.

Uma igumbi levacuum lifinyelela endaweni edingekayo yokucindezela okuphansi, okokusebenza okumele kuhwamuke kushisiswe esikebheni esihwamukayo (njengesikebhe i-W1 Pure Tungsten Boat) kusetshenziswa ukufudumeza okuphikisayo noma ukushisisa kwe-electron beam.Lapho impahla ifinyelela izinga lokushisa lokuhwamuka kwayo, iyahwamuka futhi ihambe ngomugqa oqondile iye endaweni engaphansi, lapho ifinyela khona ukuze yenze uqweqwe oluncane lwefilimu.

Imvelo ye-vacuum ephezulu ibalulekile empumelelweni yenqubo yokuhwamuka kwe-vacuum njengoba inciphisa ukuba khona kwama-molecule egesi kanye nokungcola, okuvumela ukufakwa kwekhwalithi ephezulu, amafilimu afanayo ku-substrate.
