Kwiinkqubo zokugquma nge-vacuum, ukusasazwa kwamandla ee-particles ezifikayo yinto ebalulekileyo echaphazela ukukhula kwefilimu, isakhiwo esincinci, ukunamathela, uxinano, uxinzelelo olushiyekileyo, kwaye ekugqibeleni ukusebenza kwe-optical, mechanical, kunye nokusebenza kwe-coating. Nokuba le nkqubo ibandakanya ukutshiza kwe-magnetron, i-cathodic arc deposition, i-electron-beam evaporation, okanye ezinye iiteknoloji ze-PVD, imeko yamandla ee-particles ezifikelela kwi-substrate ichaphazela ngokuthe ngqo indlela ifilimu ekhula ngayo kwaye ikhula ngayo.
Ke ngoko, umgangatho wokwaleka awunakuvavanywa ngokujonga nje izinga lokufakwa okanye ubukhulu befilimu. Ukuqonda nokulawula ukusasazwa kwamandla eesuntswana kubaluleke ngokulinganayo ekufezekiseni iipropati zefilimu ezizinzileyo kunye nokusebenza kwemveliso rhoqo.
1. Yintoni ukusasazwa kwamandla eenxalenye kwi-vacuum coating?
Ngexesha lenkqubo yokugquma nge-vacuum, ii-athomu, ii-ion, iimolekyuli, kunye nezinye iintlobo zezinto eziphilayo eziveliswe kwithagethi okanye umthombo wokufuma zihamba ngegumbi le-vacuum ukuya kwi-substrate. Ezi particles azifikeli kwi-substrate zinamandla afanayo e-kinetic. Endaweni yoko, zenza usasazo lwamandla.
Ukusasazwa kugqitywa zizinto ezifana netekhnoloji yokubeka, amandla okukhupha, uxinzelelo lokusebenza, izinto ekujoliswe kuzo, ukwakheka kwegesi, ukuthambekela kwe-substrate, umgama ukusuka kumthombo ukuya kwi-substrate, kunye neemeko zeplasma.
Umzekelo, kwi-magnetron sputtering, ii-ion ezinamandla ezivela kwi-plasma zihlasela i-target zize zikhuphe ii-athomu ezijoliswe kuzo. Ezi ntlobo zitshileyo emva koko zihamba ziye kwi-substrate, apho zijiya khona zenze i-coating. Kwi-cathodic arc deposition, inxalenye enkulu ye-deposited flux iqulethwe ziintlobo zesinyithi ezine-ionized eziphezulu ezinamandla e-kinetic aphezulu. Kwi-thermal evaporation, iintlobo zomphunga zi-athomu ezingathathi cala kakhulu ezinamandla e-kinetic aphantsi xa kuthelekiswa.
Olu mahluko kumandla eenxalenye zento yenye yezizathu ezibalulekileyo zokuba kutheni ubuchwepheshe obahlukeneyo bokugquma i-vacuum bunokuvelisa izakhiwo kunye neempawu zefilimu ezahlukeneyo.
2. Indlela Amandla eeNgcambu achaphazela ngayo ukukhula kweFilimu
Xa amasuntswana afakwe kwi-substrate afikelela kumphezulu we-substrate, amandla awo e-kinetic amisela indlela asebenzisana ngayo nomphezulu kunye nee-athomu ezifakwe ngaphambili.
Xa amandla eenxalenye ezincinci aphantsi, iintlobo ezifikayo zinokuhamba okulinganiselweyo kumphezulu. Zinokuhlala kufutshane neendawo zazo zokuqala zokufika, nto leyo ebangela ukuba kubekho isakhiwo esivulekileyo okanye esingenamibhobho. Phantsi kweemeko ezithile, oku kunokukhokelela ekukhuleni kweekholamu, ukwanda kokwakheka kwe-void, kunye noxinano oluphantsi lwefilimu.
