Munzvimbo yemazuva ano yeindasitiri iri kuchinja nekukurumidza, uko kunyatsoita zvinhu nemazvo uye kugara kwenguva refu kwakakosha, kudiwa kwetekinoroji yepamusoro yekuputira pamusoro kuri kukura. Maindasitiri akadai semotokari, ndege nemagetsi ari kuramba achitsvaga nzira itsva dzekuvandudza mashandiro, runako uye kugara kwenguva refu kwezvigadzirwa zvavo. Imwe mhinduro yakanaka yakawana kutariswa kukuru mumakore achangopfuura muchina wepurasitiki wesimbi isina ngura.
Muchina wekugadzira simbi isina ngura (vacuum coating) tekinoroji yemazuva ano yakachinja maitiro ekugadzirisa pamusoro pechinhu. Nekushandisa kamuri rekugadzira simbi, muchina uyu unokwanisa kuisa simbi isina ngura pazvinhu zvakasiyana-siyana zvinosanganisira mapurasitiki, simbi neceramics. Maitiro aya, anonzi physical vapor deposition (PVD), anogadzira nzvimbo dzine hunhu hwakanaka, dzakadai sekuoma kwakanyanya, kuramba ngura uye kunaka kwakanaka.
Michina yekuputira simbi isina ngura ine mashandisirwo akasiyana-siyana. Muindasitiri yemotokari, inoshandiswa kuputira zvinhu zvakaita sezvikamu zveinjini, mibato yemasuo nemavhiri, zvichizvipa kugara kwenguva refu uye pamusoro pesimbi isina ngura wakatsetseka. Makambani emuchadenga anovimba nehunyanzvi uhu kuchengetedza zvinhu zvakakosha zvakaita semabhura eturbine nezvinhu zvemuumbi zvinosangana nemamiriro ezvinhu akaomarara. Kunyangwe indasitiri yemagetsi inobatsirwa zvikuru nemichina yekuputira simbi isina ngura sezvo ichigona kugadzira zvinobatanidza zvisingakanganise ngura, mabhodhi edunhu uye mabhokisi emafoni.
Kufarirwa kwemichina yekuputira simbi isina ngura kunogona kukonzerwa nezvakanakira zvakawanda. Chekutanga, maitiro ePVD anobvumira kudzora kwakaringana ukobvu hwekuputira, zvichiita kuti pave nekufanana pamusoro pese. Iyi nhanho yekunyatsojeka inovimbisa kushanda kwakaringana uye kugadzikana kwekunaka. Chechipiri, nekushandisa simbi isina ngura sechinhu chekuisa, pamusoro pekuputira unoratidza kuramba kupfeka kwakanaka, kuramba kukwenya uye kuramba ngura kwemakemikari, nokudaro zvichiwedzera hupenyu hwebasa rechigadzirwa. Pamusoro pezvo, kuputira simbi isina ngura kunopa kupedzisa kwemhando yepamusoro kunoita kuti zvigadzirwa zvive nechitarisiko chakanaka uye chakanyatsonaka chinokwezva vatengi.
Pamusoro pezvo, michina yekuputira simbi isina ngura inopa imwe nzira isingakuvadzi nharaunda pane nzira dzechinyakare dzekuputira. Kusiyana nenzira dzechinyakare dzekuputira electroplating, dzinowanzo sanganisira kushandiswa kwemakemikari ane chepfu uye kugadzira mvura ine tsvina inokuvadza, maitiro ePVD mhinduro yakachena uye inogara kwenguva refu. Iyi inzira inoshanda zvikuru inogadzira marara mashoma uku ichipa kushanda kwakanaka kwekuputira. Iyi nzira isingakuvadzi nharaunda inoita kuti michina yekuputira simbi isina ngura ive sarudzo yakakurumbira kune maindasitiri ari kuedza kuderedza kukanganiswa kwavo nenharaunda.
Sezvo kudiwa kwetekinoroji yepamusoro yekuputira pamusoro kuri kuramba kuchiwedzera, mavacuum coating esimbi isina ngura ari pamberi pechinjo iyi. Kukwanisa kwayo kusimudzira mashandiro echigadzirwa, kuwedzera kugara kwenguva refu uye kuvandudza runako kunoita kuti ive chishandiso chakakosha mumaindasitiri akasiyana-siyana. Pamusoro pezvo, tekinoroji iyi ine hushamwari nezvakatipoteredza inowedzera chimwe chikamu chekukosha, zvichienderana nekutarisa kuri kukura kwepasi rose patsika dzinochengetedza nharaunda.
