Njengoba amadivayisi ezokwelapha ethuthuka ebheke ekuqondeni okuphezulu, izinqubo ezingangenisi kakhulu, kanye nokuqina okuthuthukisiwe, i-Vacuum Coating Technology isibe inqubo ebalulekile yokuguqula ubuso. Ngezindlela ezifana ne-Physical Vapor Deposition (PVD), i-Magnetron Sputtering, kanye ne-Ion Plating, amadivayisi ezokwelapha angafezi nje kuphela ukuhambisana okuhle kakhulu kwezinto eziphilayo, kodwa futhi nokusebenza okulwa namagciwane, ukumelana nokuguguleka, kanye nezimfanelo zobuhle.
I. Isimiso Sokumboza Nge-Vacuum
Ukugqoka i-vacuum kusebenzisa indawo ene-vacuum ephezulu kanye nemithombo yamandla (i-plasma, i-electron beam, noma i-arc discharge) ukuze kushiswe noma kufakwe izinto zokugqoka zibe yizinhlayiya ezinamandla, ezibe sezihlangana ebusweni bezinto zezokwelapha ukuze zakhe amafilimu amancane asebenzayo. Uma kuqhathaniswa nokufaka i-electroplating noma ukufutha kwendabuko, izinzuzo zako zifaka:
Isakhiwo esincane esiqinile sokuqina okuthuthukisiwe
Ukunamathela okuqinile phakathi kwefilimu ne-substrate
Inqubo enobungani nemvelo engenawo amanzi angcolile amakhemikhali, ehambisana nezindinganiso zokukhiqiza eziluhlaza
II. Ukusetshenziswa Kwe-Vacuum Coating Kumadivayisi Ezokwelapha
1. Amathuluzi Okuhlinzwa
Izembozo Ezivamile: I-TiN, i-ZrN, i-DLC (i-Carbon Efana Nedayimane)
Umsebenzi: Kuthuthukisa ubulukhuni bomphezulu kanye nokumelana nokuguguleka, kunciphisa i-coefficient yokungqubuzana, futhi kwandise impilo yesevisi yezikele, ama-scalpel, ama-forceps, nezinye izinsimbi.
2. Amadivayisi Angatshalwa
Izembozo Ezivamile: Ti, TiO₂, HA (Hydroxyapatite)
Umsebenzi: Izembozo ze-Ti ne-TiO₂ zinikeza ukuhambisana okuphezulu kwe-bio futhi zikhuthaza ukuhlanganiswa kwe-osseo. Izembozo ze-HA zithuthukisa umsebenzi wobuso, zenza kube lula ukunamathela kweseli kanye nokubopha kwezicubu.
3. Amadivayisi Enhliziyo Nemithambo Yegazi
Izibonelo: Ama-stents, ama-valve enhliziyo okwenziwa
Umsebenzi: Izembozo ze-DLC noma ze-TiN zinciphisa ukungqubuzana ezindaweni zokuthintana kwegazi, zinciphisa ingozi ye-thrombosis (izakhiwo zokulwa ne-thrombosis), futhi zandisa isikhathi sokuphila kwedivayisi.
4. Izinsimbi Zokuhlinza Amazinyo
Izicelo: Ukuziqeqesha kwamazinyo okumbozwe nge-TiN, ama-probe ambozwe nge-DLC
Umsebenzi: Kuthuthukisa ukumelana nokugqwala kanye nokuqina kwendawo, kuqinisekisa ukunemba okuphezulu kanye nokuqina ekusetshenzisweni kwezokwelapha.
5. Izembozo Ezilwa Namagciwane Nezivikelo
Izinto zokwakha: Ag, Cu, ZnO nanocoatings
Indlela Yokusebenza: Ukukhululwa kwe-ion okulawulwayo noma imiphumela ye-photocatalytic kuvimbela ukukhula kwamagciwane, kunciphisa ingozi yokutheleleka ngemva kokuhlinzwa.
III. Izinzuzo Zenqubo kanye Nenani Lezimboni
Ubukhulu Befilimu Elawulwayo: Ingaguqulwa ngokunembile kusukela kuma-nanometer ambalwa kuya kuma-micrometer amaningana.
Izembozo Ezihlanganisiwe Ezinemisebenzi Eminingi: Zihlanganisa ukumelana nokuguguleka, izakhiwo zokulwa namagciwane, kanye nokuhambisana kwezinto eziphilayo esitokisini esisodwa sefilimu.
Amandla Okukhiqiza Ngokuningi: Kufanelekela ukukhiqizwa okukhuliswayo embonini yamadivayisi ezokwelapha.
IV. Izitayela Zesikhathi Esizayo
Ngokuthuthuka kwamadivayisi ezokwelapha amancane nahlakaniphile, ukugqoka nge-vacuum kuzohlanganisa ubuchwepheshe be-nanotechnology kanye nokugqoka okusebenzayo kwezinto eziphilayo, okufana nalokhu:
Izembozo ezilwa namagciwane ze-Nano-silver (Ag) zokulawula ukutheleleka okuthuthukisiwe
Izembozo ze-Nano-TiO₂ photocatalytic zokusebenza isikhathi eside kokubulala amagciwane
Izembozo ezisebenzayo zokuthuthukisa ukusebenza kahle kokulethwa kwemithi
Isiphetho
Ukugqoka i-vacuum akuyona nje indlela yokuthuthukisa ukubukeka nokuqina kwamadivayisi ezokwelapha; kuwubuchwepheshe obubalulekile bokuthuthukisa ukuphepha nokusebenza. Kusukela kumathuluzi okuhlinza kuya kuma-implants, kusukela kuma-stent kuya kumathuluzi amazinyo, ukugqoka i-vacuum sekuvele kuyisisombululo sobunjiniyela bendawo esibalulekile embonini yezokwelapha.
