Intshayelelo:
Wamkelekile kwakhona kuthotho lwethu lweebhlog malunga nenkqubo ye-PVD (Physical Vapor Deposition)! Kweli nqaku, siza kujonga nzulu amanyathelo asisiseko afunekayo ukuze kufezekiswe iziphumo ezigqwesileyo ngokubeka i-PVD. Ngokuyila inkqubo yokufaka i-PVD, unokuphucula ukuqina, ukumelana nokugqwala kunye nobuhle beemveliso zakho. Nceda ujoyine nathi njengoko sihlola izinto eziphambili ezinegalelo kwiziphumo zokufaka i-PVD eziphumelelayo.
Ukuqonda ukubekwa kwePVD:
Ukufakwa kwePVD yindlela esetyenziswa kakhulu yokufaka iifilimu ezincinci kunye neengubo kwiindawo ezahlukeneyo ezifana neentsimbi, iiseramikhi kunye neeplastiki. Le nkqubo ibandakanya ukufuma kwezinto eziqinileyo kulandele ukujiya kwi-substrate, kwenze ifilimu encinci. Iingubo ezivelayo zihlala zibonisa iimpawu eziphuculweyo ezifana nokuqina, ukumelana nokukrweleka kunye nenkangeleko ekhazimlayo.
Amanyathelo aphambili okuphucula ukufakwa kwePVD:
1. Ukulungiswa komphezulu: Ukulungiswa komphezulu kubaluleke kakhulu ngaphambi kokuba kuqaliswe inkqubo yokufaka i-PVD. Ukucoca ngokucokisekileyo, ukupolisha kunye nokususa amafutha kwi-substrate kuya kususa ukungcola, kuqinisekise ukunamathela ngokufanelekileyo kwaye kuthintele iziphene. Umphezulu ococekileyo ukhuthaza ukunamathela okungcono kokugquma kwaye uphucula umgangatho uphela wediphozithi.
2. Igumbi lokubeka izinto: Indawo ecocekileyo nelawulwayo ibalulekile ukuze kubekho i-PVD ephumelelayo. Igumbi lokubeka izinto ligcinwa liphantsi koxinzelelo kunye nobushushu obulawulwayo, nto leyo evumela ii-athomu okanye iimolekyuli eziphekwe ngomphunga ukuba zihambe ngokukhululekileyo ngaphandle kokuphazamiseka. Ukukhetha ngokufanelekileyo iiparameter zokubeka izinto ezifana noxinzelelo, ubushushu kunye nexesha lokubeka izinto kuqinisekisa ubukhulu befilimu obuchanekileyo kunye nokufana ukuze kufunyanwe iziphumo ezilungileyo.
3. Ukukhethwa komthombo wokufuma: Ukukhethwa komthombo wokufuma kuyichaphazela kakhulu inkqubo yokufakwa kwePVD. Izinto ezikhethiweyo kufuneka zibe msulwa kakhulu ukuqinisekisa umgangatho wefilimu. Imithombo yokufuma ethandwayo ibandakanya iinqanawa ezifudumezayo ezihlala ziqinile, imithombo ye-electron beam, okanye ii-cathode ze-magnetron sputtering, nganye yenzelwe ukuhlangabezana neemfuno ezithile.
4. Ukubeka iliso kwifilimu kunye nokulawula ubukhulu: Ukubeka iliso ngexesha langempela kunye nokulawula ngokuchanekileyo ubukhulu befilimu kubalulekile ekubekweni kwePVD rhoqo nangokuchanekileyo. Ubuchwepheshe banamhlanje obufana ne-quartz crystal microbalances kunye neenkqubo zokubeka iliso ezibonakalayo zivumela ulawulo oluphuculweyo kunye nohlengahlengiso ngexesha lenkqubo yokufaka. Ukugcina ubukhulu befilimu obaneleyo kuqinisekisa ukusebenza okufunekayo kunye nokusebenza.
5. Unyango emva kokufakwa kwePVD: Emva kokuba ukufakwa kwePVD kugqityiwe, amanyathelo emva konyango anokuphucula ngakumbi iimpawu zefilimu. Ukuqhoboshela, ukuqhushumba kweion, okanye ukugrumba kweion ziindlela ezisetyenziswa kakhulu ukuphucula ukunamathela, ukugqitywa komphezulu, kunye nokunciphisa uxinzelelo lweefilimu ezifakwe kuyo. Unyango olufanelekileyo emva kokufakwa kwePVD luqinisekisa ukuba ii-PVD coating zihlala ixesha elide kwaye zisebenza kakuhle.
