Indlela i-PVD Esebenza Ngayo: Ukwembula Izimfihlo Zalobu Buchnoloji Obusezingeni Eliphezulu
Insimu yokuthuthuka kwezobuchwepheshe ishintsha njalo, inikeza izixazululo ezintsha zezimboni ezahlukene. Enye yentuthuko enjalo ubuchwepheshe be-PVD (Physical Vapor Deposition), obuletha isici esisha kubunjiniyela bomphezulu. Kulesi sihloko sebhulogi, sizohlola ngokujulile ukuthi i-PVD isebenza kanjani futhi sihlole ukuthi lobu buchwepheshe obumangalisayo buguqula kanjani izinkambu eziningana.
I-PVD, njengoba igama lisho, ihilela ukufaka amafilimu amancane ezindaweni eziqinile ngenqubo ebonakalayo. Ubuchwepheshe busebenzisa izimiso ezihlukile ukuthuthukisa ukuqina, ukusebenza kanye nobuhle bemikhiqizo eyahlukahlukene. Ngakho-ke, ake sihlole ngokujulile ukuthi i-PVD isebenza kanjani futhi siqonde ukuthi isho ukuthini.
Ingqikithi ye-PVD ukudala indawo yokuhlanza ngaphakathi kwegumbi eliklanywe ngokukhethekile. Le vacuum iqinisekisa ukususwa kwanoma yikuphi ukungcola, okuhlinzeka ngendawo efanelekile yenqubo yokumboza. Uma igumbi elivalwe nge-hermetic selivaliwe, izinto eziqondiwe (okungaba yinsimbi, i-alloy, i-ceramic noma ngisho ne-polymer) zishiswa kakhulu. Ngenxa yalokho, ama-athomu noma ama-molecule ezintweni eziqondiwe aguquka abe yisimo segesi.
Manje sekuza ingxenye ebalulekile yendlela i-PVD esebenza ngayo – ukufaka la ma-athomu noma ama-molecule egesi phezu kwento oyifunayo. Ukuze kufezwe lokhu, kudingeka umthombo wamandla aphezulu njenge-arc noma i-plasma. Lo mthombo wamandla uhlasela ama-athomu, okwenza ahlakazeke futhi akhe ifu le-plasma. Ifu le-plasma libe selisunduzela ama-athomu phezulu, lapho ama-athomu ehlangana khona bese enza ifilimu encane.
Inqubo ye-PVD inikeza izinzuzo eziningana kunezindlela zokumboza zendabuko. Okokuqala, ivumela ukulawulwa okunembile kobukhulu kanye nokwakheka kwefilimu efakiwe. Abakhiqizi bangafinyelela ukumboza ngokufana okuhle kakhulu, ngisho nasezimo eziyinkimbinkimbi kanye nemininingwane eyinkimbinkimbi. Okwesibili, ifilimu ye-PVD inokunamathela okuhle kakhulu ku-substrate, okuqinisekisa ukuthi ihlala isikhathi eside futhi imelana nokuguguleka. Ngaphezu kwalokho, ubuchwepheshe be-PVD buvumela ukufakwa kokumboza okunezici ezihlukile njengokuqina okuphezulu, ukungqubuzana okuphansi kanye nokumelana nokugqwala okuhle kakhulu.
Ukusetshenziswa kwe-PVD kubanzi kakhulu futhi kuhilela izimboni ezahlukahlukene. Kusukela ezingxenyeni zezimoto namathuluzi okusika kuya ekuqedeni kokuhlobisa namadivayisi ezokwelapha, lobu buchwepheshe bushintsha indlela esisebenzisana ngayo nemikhiqizo yansuku zonke. Isibonelo, izembozo ze-PVD kumathuluzi okusika zingandisa kakhulu impilo yazo yesevisi, zinciphise isidingo sokushintshwa njalo. Ngokufanayo, izembozo ze-PVD ezingxenyeni zezimoto zandisa ukuqina nokusebenza kahle kwazo, zisize ekuthuthukiseni ukonga uphethiloli nokunciphisa ukukhishwa kwegesi.
Muva nje kwembulwe ukuthi ososayensi bebehlola amandla okusebenza kwe-PVD emandleni avuselelekayo. Ngokusebenzisa izembozo ze-PVD kumaphaneli elanga, abacwaningi bahlose ukwandisa ukusebenza kahle kwazo kanye nokuphila kwazo. Ngokufanayo, izembozo ze-PVD ezitsheni ze-wind turbine zingandisa ukumelana kwazo nokuguguleka, ngaleyo ndlela zandise ukukhiqizwa kwamandla.
Isimiso sendlela i-PVD esebenza ngayo siyindlela entsha emangalisayo eguqule ubunjiniyela bomphezulu. Ngokulawula nokufaka amafilimu amancane ngokunembile, izembozo ze-PVD zithuthukisa ukuqina, ukusebenza kanye nobuhle bemikhiqizo eyahlukahlukene. Ngezinhlelo zazo ezahlukahlukene ezimbonini, lobu buchwepheshe obusezingeni eliphezulu buyaqhubeka nokuvula indlela yentuthuko eyengeziwe. Hlala ubukele njengoba sembula okunye okuthokozisayo emkhakheni we-PVD.
