Indlela I-PVD Esebenza Ngayo: Kwembula Izimfihlo Zalobu buchwepheshe Be-Cutting-Edge
Umkhakha wokuthuthuka kwezobuchwepheshe uhlala uvela, uhlinzeka ngezixazululo ezintsha ezimbonini ezihlukahlukene. Okunye okuthuthukile okunjalo ubuchwepheshe be-PVD (Physical Vapor Deposition), obuletha isici esisha kubunjiniyela bangaphandle. Kulokhu okuthunyelwe kwebhulogi, sizongena ngokujulile endleleni i-PVD esebenza ngayo futhi sihlole ukuthi lobu buchwepheshe obumangalisayo buguqula kanjani izinkambu ezimbalwa.
I-PVD, njengoba negama libonisa, ihilela ukufaka amafilimu amancanyana endaweni eqinile ngokusebenzisa inqubo engokomzimba. Ubuchwepheshe busebenzisa izimiso ezihlukile ukuze kuthuthukiswe ukuqina, ukusebenza kanye nobuhle bemikhiqizo ehlukahlukene. Ngakho-ke, ake singene sijule ekutheni i-PVD isebenza kanjani futhi siqonde ukuthi isho ukuthini.
Ingqikithi ye-PVD iwukwenza indawo ye-vacuum ngaphakathi kwekamelo eliklanywe ngokukhethekile. Le vacuum iqinisekisa ukususwa kwanoma yikuphi ukungcola, inikeze indawo ekahle yenqubo yokumboza. Uma igumbi le-hermetic selivaliwe, into ehlosiwe (okungaba insimbi, ingxubevange, i-ceramic noma i-polymer) ifakwa ekushiseni okukhulu. Ngenxa yalokho, ama-athomu noma ama-molecule ezinto eziqondiwe ashintsha abe isimo segesi.
Manje sekuza ingxenye ebalulekile yendlela i-PVD esebenza ngayo - ukufaka lawa ma-athomu egesi noma ama-molecule phezu kwento oyifunayo. Ukufeza lokhu, umthombo wamandla ophezulu njenge-arc noma i-plasma uyadingeka. Lomthombo wamandla uqhumisa ama-athomu, uwabangele ahlakazeke akhe ifu le-plasma. Ifu le-plasma libe selidudulela ama-athomu phezulu, lapho ama-athomu acinana enze ifilimu encane.
Inqubo ye-PVD inikeza izinzuzo eziningana kunezindlela zendabuko zokuhlanganisa. Okokuqala, ivumela ukulawula okunembile kokuqina nokwakheka kwefilimu efakiwe. Abakhiqizi bangakwazi ukufeza ama-coatings ngokufana okuhle kakhulu, ngisho nasezimo eziyinkimbinkimbi kanye nemininingwane eyinkimbinkimbi. Okwesibili, ifilimu ye-PVD inokunamathela okuhle kakhulu ku-substrate, iqinisekisa ukuphila isikhathi eside nokumelana nokugqoka. Ngaphezu kwalokho, ubuchwepheshe be-PVD buvumela ukubekwa kwezingubo ezinezakhiwo ezihlukile njengokuqina okuphezulu, ukungqubuzana okuphansi kanye nokumelana nokugqwala okuhle kakhulu.
Ukusetshenziswa kwe-PVD kubanzi kakhulu futhi kuhilela izimboni ezihlukahlukene. Kusukela ezingxenyeni zezimoto namathuluzi okusika kuya emaqenjini okuhlobisa kanye nemishini yezokwelapha, lobu buchwepheshe bushintsha indlela esisebenzisana ngayo nemikhiqizo yansuku zonke. Isibonelo, ukumbozwa kwe-PVD kumathuluzi okusika kunganweba kakhulu impilo yabo yesevisi, kunciphise isidingo sokushintshwa njalo. Ngokunjalo, izimbobo ze-PVD ezingxenyeni zezimoto zikhulisa ukuqina nokusebenza kahle kwazo, zisiza ukuthuthukisa ukonga kukaphethiloli nokunciphisa ukukhishwa kwekhabhoni.
Muva nje kuye kwavezwa ukuthi ososayensi bebehlola amandla okuthi i-PVD isebenza kanjani emandleni avuselelekayo. Ngokusebenzisa izimbotshana ze-PVD kumaphaneli elanga, abacwaningi bahlose ukukhulisa ukusebenza kahle kwabo nempilo yabo yonke. Ngokufanayo, izimbobo ze-PVD ezinsikeni ze-turbine yomoya zingandisa ukumelana kwazo nokuguguleka, ngaleyo ndlela kwandise ukukhiqizwa kwamandla.
Umgomo wendlela i-PVD esebenza ngayo iwukuqanjwa okusha okuphawulekayo okuguqule ubunjiniyela baphezulu. Ngokulawula kahle kanye nokufaka amafilimu amancane, izimbotshana ze-PVD zithuthukisa ukuqina, ukusebenza kanye nobuhle bemikhiqizo ehlukahlukene. Ngokusetshenziswa kwayo okuhlukahlukene kuzo zonke izimboni, lobu buchwepheshe obusezingeni eliphezulu buyaqhubeka nokuvula indlela yentuthuko eyengeziwe. Hlala ubukele njengoba sembula okunye okuthakazelisayo okutholakele emkhakheni we-PVD.
