Kutarisana nekukura kwefirimu kune simba guru. Kana kuomarara kwepamusoro pe substrate kuri kukuru, uye kuchiwedzera kusanganiswa nezvikanganiso zvepamusoro, zvinokanganisa kubatana uye mwero wekukura kwefirimu. Nokudaro, usati watanga kuputira vacuum, substrate ichave ichigadziriswa, iyo inotamba basa rekuomarara kwepamusoro pe substrate pamusoro pe substrate. Mushure mekupindira kwe ultrasonic, pamusoro pe substrate pachaumbwa kukwakuka kudiki, izvo zvinowedzera nzvimbo yekubata yezvikamu zvitete zvefirimu uye pamusoro pe substrate, izvo zvinogona kuwedzera zvakanyanya chimiro che rotor uye musanganiswa we membrane base.
Kune zvakawanda zvezvinhu zve substrate, sezvo kuomarara kwe substrate kuchiderera, kunamira kwefirimu kunowedzera, kureva kuti, simba rekubatanidza base membrane rinosimba; kunewo zvimwe zvinhu zve substrate zviri zviitiko zvakakosha, zvakaita sekubatanidza firimu ye ceramic base. Dhigirii dzakaderera, kureva kuti, simba rekubatanidza base membrane rinopera simba.
Muzvinhu zvinopesvedzera zvinoenderana nefirimu nefirimu, thermal bulk coefficient inoita basa guru. Kana thermal expansion coefficient yefirimu yakakura kupfuura thermal expansion coefficient ye matrix, torque inenge isina kunaka, uye maximum tension iri pa free boundary. Iri pedyo nepakati pepakati kuti iome, uye firimu rinogona kuita serakaiswa layer. Tora sedimentary Skinus thin film semuenzaniso. Nekuti thermal expansion coefficient yedhaimani idiki, kana gas phase deposition yapera, substrate tembiricha inodzikiswa kubva pa sedimentary tembiricha yakakwira kuenda pa room temperature, uye contraction yedhaimani inodzikiswa zvichienzaniswa ne substrate. Thermal stress huru ichaburitsa mukati. Kana thermal expansion coefficient yefirimu iri pasi pe heating ledger coefficient ye substrate, torque inenge yakanaka, uye firimu harisi nyore kuisa layer.
