Ukujongana nokukhula kwefilimu kunempembelelo ebaluleke kakhulu. Ukuba uburhabaxa bomphezulu be-substrate bukhulu, kwaye budibene ngakumbi kunye neziphene zomhlaba, kuya kuchaphazela ukudibanisa kunye nesantya sokukhula kwefilimu. Ngoko ke, ngaphambi kokuba i-vacuum coating iqale, i-substrate iya kulungiswa kwangaphambili, edlala indima yobunzima bomhlaba we-substrate ebusweni be-substrate. Emva kokungenelela kwe-ultrasonic, umphezulu we-substrate uya kwenza i-scratch encinci, eyandisa indawo yoqhagamshelwano yeengqungquthela zefilimu ezincinci kunye nobuso be-substrate, enokunyusa kakhulu ukusesikweni kwe-rotor kunye nokudibanisa isiseko se-membrane.
Uninzi lwezixhobo ze-substrate, njengoko uburhabaxa be-substrate buyancipha, ukunamathela kwefilimu kuyanda, oko kukuthi, isiseko se-membrane esibophezelayo siyaqina; kukho kwakhona ezinye izinto ze-substrate eziziimeko ezikhethekileyo, ezifana ne-attachment yefilimu yesiseko se-ceramic. Ukunciphisa amadigri, oko kukuthi, amandla okubopha isiseko se-membrane ayancipha.
Kwimiba echaphazelayo ehambelana nefilimu kunye nefilimu, i-coefficient ye-thermal bulk idlala indima ebalulekileyo. Xa i-coefficient yokwandiswa kwe-thermal yefilimu inkulu kune-coefficient yokwandiswa kwe-thermal ye-matrix, i-torque ayinayo, kwaye uxinzelelo oluphezulu lusemda wamahhala. Ikufutshane embindini weziko ukuba ixinzelelwe, kwaye ifilimu inokuvela ifakwe umaleko. Thatha ifilimu yentlenga ye-Skinus ebhityileyo njengomzekelo. Ngenxa yokuba i-coefficient yokwandisa i-thermal yedayimani incinci, xa ukubekwa kwesigaba segesi kuphelile, ubushushu be-substrate buyancipha ukusuka kubushushu obuphezulu be-sedimentary ukuya kubushushu begumbi, kwaye ukucutha kwedayimani kuyancipha xa kuthelekiswa ne-substrate. Uxinzelelo olukhulu lwe-thermal luya kuvelisa ngaphakathi. Xa i-coefficient yokwandisa i-thermal yefilimu ingaphantsi kwe-coefficient ye-ledger yokufudumala ye-substrate, i-torque ilungile, kwaye ifilimu ayilula ukuyibeka.
