Kwisakhelo setekhnoloji yeizixhobo zokugquma nge-vacuum,Uyilo lokuphinda kuvele kwakhona aluyondlela yokulinganisa encedisayo, kodwa lubuchule obusisiseko obufakwe kuyo yonke inkqubela phambili yezixhobo, ukuphunyezwa kwenkqubo, kunye nemveliso enkulu. Ingakumbi kwizicelo ezifana nezixhobo zangaphakathi zeemoto, izinto ezibonakalayo, kunye neefilimu ezisebenzayo—apho ukuhambelana okuphezulu kuyimfuneko—ukuphinda kuvele kwakhona kwezixhobo kuchazwa ngokuthe ngqo ukulawulwa kweempawu zefilimu kunye nomda ophezulu wokwenziwa okunokwandiswa.
Ngokwembono yenkqubo, i-vacuum coating yiteknoloji yokuvelisa exhomekeke kakhulu kulawulo oludibeneyo lweeparameter ezininzi. Nokuba kwiinkqubo ze-physical vapor deposition (PVD) ezifana ne-magnetron sputtering kunye ne-thermal evaporation, okanye kwiinkqubo ze-hybrid deposition, ulwakhiwo lwefilimu, ukusebenza kwe-optical, kunye nokunamathela konke kulawulwa ziinguqu eziquka inqanaba le-vacuum, uxinano lwe-plasma, izinga lokufakwa, ubushushu be-substrate, kunye nemeko ekujoliswe kuyo. Kule meko, injongo ephambili yoyilo lokuphinda uvelise kukuqinisekisa ukuba ezi parameter zibalulekileyo zihlala zihambelana kakhulu kwiibhetshi ezahlukeneyo kunye nexesha ngokusebenzisa ukulungiswa okucwangcisiweyo koyilo lwezixhobo, iinkqubo zolawulo, kunye neendlela zenkqubo-ngaloo ndlela kuvumela ukusebenza kwefilimu okuphindaphindwayo.
Ukuphinda-phinda kubonakala kuqala ekuzinzeni kwenkqubo yokufunxa. Ijika lokufunxa eliqikelelweyo kunye nenqanaba elizinzileyo lokufunxa zenza isiseko sendawo ehambelanayo yenkqubo. Ngokudibanisa ngokufanelekileyo iimpompo ezingasemva, iimpompo zeRoots, kunye neempompo ezine-vacuum ephezulu (ezifana neempompo ze-turbomolecular okanye ze-diffusion), kunye namaqhinga okulawula uxinzelelo oluvaliweyo, umahluko phakathi kwemijikelo unokunciphisa ngempumelelo. Ukongeza, uyilo lwegumbi elilinganayo kunye nokusasazwa kokuhamba kwegesi okufanayo kudlala indima ebalulekileyo kuzinzo lweplasma kunye nokufana kwefilimu, okwenza isiseko solwakhiwo lokuphinda-phinda.
Kwiinkqubo zemithombo yokubeka, nokuba kulawulo lwentsimi yobushushu yemithombo yokufuma okanye ukufana kwentsimi yemagnethi yeethagethi zokufutha zemagnetron, ulungelelwaniso olusemgangathweni lubalulekile ukugcina ubudlelwane obuzinzileyo phakathi kokufakwa kwamandla kunye nemveliso yezinto. Umzekelo, ukuhambelana kweeprofayili zokukhukuliseka ekujoliswe kuko ekufutheni kuchaphazela ngokuthe ngqo izinga lokubeka kunye nokusasazwa kobukhulu, ngelixa kwiinkqubo zokufuma, impendulo ethe ngqo phakathi kwamandla okufudumeza kunye nezinga lokufuma imisela ukuchaneka kolawulo lobukhulu. Ezi nkalo zifuna ukuqinisekiswa okungqongqo kokuphinda kuvele kwinqanaba loyilo, endaweni yokuxhomekeka kwimbuyekezo yasemva kwenkqubo.
Ukwenziwa kwedijithali kunye nokuguqulwa kweenkqubo zolawulo kuxhasa ngakumbi uyilo lokuphinda kuvele. Ngezinzwa ezichanekileyo, ukufunyanwa kwedatha ngexesha langempela, kunye nee-algorithms zokulawula impendulo, iiparameter zenkqubo eziphambili zinokujongwa ngokuguquguqukayo kwaye zilungiswe kwiiluphu ezivaliweyo, kunciphisa kakhulu ukuguquguquka okubangelwa kukusebenza ngesandla. Kwangaxeshanye, iinkqubo zolawulo lweresiphi ezisemgangathweni zivumela ukutshintsha kwemveliso ngokukhawuleza ngelixa kuqinisekiswa ukulandeleka ngokupheleleyo kunye nokuphindaphinda ngokuchanekileyo kweeparameter zenkqubo yembali, okwenza umqolo wemveliso enokwandiswa.
Ngaphaya kokusebenza kwezixhobo esinye, ukuphinda-phinda kukwasisiseko sokuhambelana kwinqanaba lomgca wemveliso. Kwiinkqubo zokugquma eziqhubekayo zamagumbi amaninzi kunye nezitishi ezininzi, ukulungelelaniswa kweeparameter kunye nokuvumelanisa kwe-takt phakathi kweemodyuli kuchaphazela ngokuthe ngqo ukuphuma kunye nemveliso. Ke ngoko, ukuphinda-phinda kufuneka kufakwe kuyilo lwenqanaba lenkqubo—ukusuka kwigumbi ngalinye ukuya kwimigca yemveliso edityanisiweyo ngokupheleleyo—ukuthintela ukungalingani okubangelwa kukwenziwa ngcono okuzimeleyo.
Ngokwembono yezicelo zokusetyenziswa kokugqibela, ixabiso lokuphinda kuvele libonakala kwiinkalo ezininzi. Kwizinto zangaphakathi zeemoto, ukuhambelana kombala wefilimu kunye nokufana kwe-gloss kuchaphazela ngokuthe ngqo umgangatho obonwayo; kwiingubo zokukhanya, ukuphambuka kobukhulu kunokukhokelela kutshintsho olucwangcisiweyo ekudluliseleni nasekubonakaliseni; kwiingubo ezisebenzayo, ukuguquguquka kokunamathela kunye nokuqina kuchaphazela ukuthembeka komjikelo wobomi bemveliso. Zonke ezi zibonakaliso zokusebenza ekugqibeleni zixhomekeke ekuphindaphindeni kwezixhobo zokugquma.
Ngokwenyani, ukugxininisa kuyilo lokuphinda-phinda akupheleli nje “ekwenzeni into enye ngalo lonke ixesha,” kodwa malunga nokwakha iqonga lokuvelisa elinokuqikelelwa, elilawulekayo, neliphindaphindwayo ngaphakathi kwenkqubo enzima neguquguqukayo. Olu buchule lubonisa umahluko ophambili kwezobuchwepheshe kwiinkqubo zokugquma i-vacuum eziphambili kunye nesiseko esibalulekileyo sokuvelisa okusemgangathweni ophezulu, okukhulu.
