Kuyini ukumelana nomthombo we-evaporation?

I-Resistance evaporation source coating iyindlela eyisisekelo ye-vacuum evaporation coating.“Ukuhwamuka” kubhekisela endleleni yokulungiselela ifilimu elincanyana lapho okokunamathelayo kugumbi levacuum kushisiswe futhi kuhwamuke, ukuze ama-athomu abalulekile noma ama-molecule ahwamuke futhi aphume phezulu, enze into egeleza umhwamuko, isigameko ebusweni be-vacuum. i-substrate noma i-substrate, futhi ekugcineni ifinyezwe ukwenza ifilimu eqinile.

Le ndlela ebizwa ngokuthi ukumelana nokuhwamuka komthombo we-resistance ukusebenzisa i-tantalum, i-molybdenum, i-tungsten nezinye izinsimbi ezincibilika kakhulu ukwenza isimo esifanelekile somthombo wokuhwamuka, olayishwa ngezinto ezizohwamuka, uvumele umoya ugeleze, ukushisa ngqo kanye nokuhwamuka. zihwamulise izinto ezihwamukile, noma ubeke izinto ezizohwamuka zibe yi-alumina, i-beryllium oxide nezinye izinsimbi zokushisisa nokuhwamuka okungaqondile.Lena yindlela yokuhwamuka kokushisa kokumelana.

Iumshini wokugcwalisa i-vacuum evaporationukushisisa nokuhwamuka yi-heater yokumelana kunezinzuzo zesakhiwo esilula, izindleko eziphansi kanye nokusetshenziswa okuthembekile.Ingasetshenziselwa ukuhwamuka kwezinto ezinephuzu elincibilikayo eliphansi, ikakhulukazi ekukhiqizeni ngobuningi ngezidingo eziphansi zekhwalithi yokumboza.Kuze kube manje, kusekhona inqwaba yezinqubo zokumboza zokushisa kokumelana nokuhwamuka okusetshenziselwa ukukhiqizwa kwezibuko ze-aluminium.

Ukungalungi kwe-resistance evaporation source evaporation coating indlela yokuthi izinga lokushisa eliphezulu elingafinyelelwa ngokushisa lilinganiselwe, futhi impilo yesevisi ye-heater nayo ifushane.Eminyakeni yamuva nje, ukuze kuthuthukiswe impilo yomthombo wokuhwamuka kokumelana, ifekthri yemishini yamukele impahla yobumba eqhutshwayo ehlanganiswe yi-boron nitride enempilo ende njengomthombo wokuhwamuka.Ngokombiko welungelo lobunikazi laseJapane, ingasebenzisa izinto ezakhiwe nge-20% ~ 30% ye-boron nitride nezinto eziphikisayo ezingahlanganiswa nayo ukuze yenze umthombo wokuhwamuka (oku-crucible), futhi imboze ubuso bayo ngongqimba lwe-zirconium equkethe u-62% ~ 82%, kanti ezinye izinto ze-zirconium-silicon alloy.
