Ukubhekana nokukhula kwefilimu kunomthelela obaluleke kakhulu. Uma ubulukhuni obungaphezulu be-substrate bukhulu, futhi buhlanganiswa kakhulu nokukhubazeka kwendawo, kuzothinta ukunamathiselwa kanye nezinga lokukhula kwefilimu. Ngakho-ke, ngaphambi kokuba i-vacuum coating iqale, i-substrate izobe icutshungulwa ngaphambili, edlala indima yobunzima obungaphezulu be-substrate ebusweni be-substrate. Ngemuva kokungenelela kwe-ultrasonic, ubuso be-substrate buzokwenza i-scratch encane, okwandisa indawo yokuxhumana yezinhlayiya zefilimu encane kanye nobuso be-substrate, okungakwandisa kakhulu ukuhleleka kwe-rotor kanye nokuhlanganiswa kwesisekelo se-membrane.
Ngezinto eziningi ze-substrate, njengoba ukuqina kwe-substrate kuncipha, ukunamathela kwefilimu kuyanda, okungukuthi, amandla okubopha isisekelo se-membrane kuba namandla; kukhona futhi ezinye izinto ze-substrate ezingamacala akhethekile, njengokunamathiselwe kwefilimu yesisekelo se-ceramic. Amadigri anciphile, okungukuthi, amandla okubopha isisekelo se-membrane aba buthaka.
Ezicini ezinomthelela ezifana nefilimu nefilimu, i-thermal bulk coefficient idlala indima ebalulekile. Uma i-coefficient yokwandisa okushisayo yefilimu inkulu kune-coefficient yokwandisa ukushisa kwe-matrix, i-torque iyinegethivu, futhi ukungezwani okuphezulu kusemngceleni wamahhala. Iseduze nendawo emaphakathi ukuze iminyaniswe, futhi ifilimu ingase ibonakale igqinsile. Thatha ifilimu elincanyana le-Skinus njengesibonelo. Ngenxa yokuthi i-coefficient yokwandisa okushisayo yedayimane incane, lapho ukufakwa kwesigaba segesi sekuphelile, izinga lokushisa le-substrate liyehla lisuka kuzinga lokushisa eliphakeme le-sedimentary liye kuzinga lokushisa lekamelo, futhi ukufinyela kwedayimane kuyehla uma kuqhathaniswa ne-substrate. Ukucindezeleka okukhulu okushisayo kuzokhiqiza ngaphakathi. Uma i-coefficient yokwandisa okushisayo yefilimu ingaphansi kwe-coefficient yeleja yokushisa ye-substrate, i-torque ilungile, futhi ifilimu akulula ukuyibeka.
