Mmene PVD Imagwirira Ntchito: Kuvumbulutsa Zinsinsi za Ukadaulo Wodula Uwu
Gawo lachitukuko chaukadaulo likukula mosalekeza, ndikupereka mayankho aukadaulo amakampani osiyanasiyana. Kumodzi kopambana kotereku ndiukadaulo wa PVD (Physical Vapor Deposition), womwe umabweretsa gawo latsopano paukadaulo wapamwamba. Mu positi iyi yabulogu, tizama mozama momwe PVD imagwirira ntchito ndikuwona momwe ukadaulo wodabwitsawu ukusinthira magawo angapo.
PVD, monga momwe dzinalo likusonyezera, imaphatikizapo kuyika mafilimu opyapyala pamalo olimba pogwiritsa ntchito thupi. Ukadaulowu umagwiritsa ntchito mfundo zapadera kuti zithandizire kukhazikika, magwiridwe antchito komanso kukongola kwazinthu zosiyanasiyana. Chifukwa chake, tiyeni tipende mozama momwe PVD imagwirira ntchito ndikumvetsetsa tanthauzo lake.
Chofunikira cha PVD ndikupanga malo opanda mpweya mkati mwa chipinda chopangidwa mwapadera. Vutoli limatsimikizira kuchotsedwa kwa zonyansa zilizonse, zomwe zimapereka malo abwino opangira zokutira. Chipinda cha hermetic chikasindikizidwa, chinthu chomwe mukufuna (chomwe chingakhale chitsulo, aloyi, ceramic kapena polima) chimatenthedwa kwambiri. Zotsatira zake, ma atomu kapena mamolekyu omwe ali muzinthu zomwe akufuna amasintha kukhala mpweya.
Tsopano pakubwera gawo lofunikira la momwe PVD imagwirira ntchito - kuyika maatomu a mpweya kapena mamolekyuwa pamwamba pa chinthu chomwe mukufuna. Kuti izi zitheke, gwero lamphamvu kwambiri monga arc kapena plasma likufunika. Gwero lamphamvu limeneli limaphulitsa maatomu, kuwapangitsa kusweka ndi kupanga mtambo wa plasma. Kenako mtambo wa plasma umakankhira maatomuwo kumtunda, kumene maatomuwo amaunjikana ndi kupanga filimu yopyapyala.
Njira ya PVD imapereka maubwino angapo kuposa njira zachikhalidwe zokutira. Choyamba, zimalola kuwongolera bwino makulidwe ndi kapangidwe ka filimu yoyikidwa. Opanga amatha kukwaniritsa zokutira ndi zofanana kwambiri, ngakhale pamawonekedwe ovuta komanso mwatsatanetsatane. Chachiwiri, filimu ya PVD ili ndi kumamatira kwabwino kwambiri ku gawo lapansi, kuonetsetsa kuti moyo wautali ndi kukana kuvala. Kuphatikiza apo, ukadaulo wa PVD umathandizira kuyika kwa zokutira zokhala ndi zinthu zapadera monga kuuma kwakukulu, kukangana kochepa komanso kukana kwambiri kwa dzimbiri.
Kugwiritsa ntchito PVD ndikwambiri ndipo kumakhudza mafakitale osiyanasiyana. Kuchokera ku zida zamagalimoto ndi zida zodulira mpaka zomaliza zokongoletsa ndi zida zamankhwala, ukadaulo uwu ukusintha momwe timalumikizirana ndi zinthu zatsiku ndi tsiku. Mwachitsanzo, zokutira za PVD pazida zodulira zimatha kukulitsa moyo wawo wautumiki, kuchepetsa kufunika kosinthira pafupipafupi. Momwemonso, zokutira za PVD pazigawo zamagalimoto zimakulitsa kulimba kwawo komanso kuchita bwino, kumathandizira kupititsa patsogolo chuma chamafuta ndikuchepetsa kutulutsa mpweya.
Posachedwapa zadziwika kuti asayansi akhala akufufuza kuthekera kwa momwe PVD imagwirira ntchito mu mphamvu zowonjezera. Pogwiritsa ntchito zokutira za PVD pamagetsi oyendera dzuwa, ofufuza akufuna kuwonjezera luso lawo komanso moyo wawo wonse. Momwemonso, zokutira za PVD pamasamba a turbine yamphepo zimatha kukulitsa kukana kwawo kukokoloka, motero kumawonjezera kupanga mphamvu.
Mfundo ya momwe PVD imagwirira ntchito ndi luso lodabwitsa lomwe lasintha uinjiniya wapamwamba kwambiri. Mwa kuwongolera bwino ndikuyika mafilimu opyapyala, zokutira za PVD zimakulitsa kulimba, magwiridwe antchito ndi kukongola kwazinthu zosiyanasiyana. Ndi kugwiritsa ntchito kwake kosiyanasiyana m'mafakitale, ukadaulo wapamwambawu ukupitilizabe kupititsa patsogolo chitukuko. Khalani tcheru pamene tikuwulula zinthu zosangalatsa zomwe zapezedwa m'gawo la PVD.
