Idayimani eyenziwe nge-chemical bonding enamandla ineempawu ezikhethekileyo zoomatshini kunye ne-elastic. Ubunzima, uxinano kunye ne-thermal conductivity yedayimani zezona ziphezulu phakathi kwezinto ezaziwayo. Idayimani ikwanayo ne-modulus ephezulu ye-elasticity yayo nayiphi na into. I-coefficient ye-fricsion yefilimu yedayimani yi-0.05 kuphela. Ukongeza, idayimani ine-thermal conductivity ephezulu, eyanda ngaphezu kwesihlanu ukuba ifilimu yedayimani ilungiselelwe kusetyenziswa ii-isotopes ezicocekileyo zekhabhoni. Isizathu esiphambili sokusebenzisa ii-isotopes zekhabhoni ukulungiselela idayimani kukunciphisa ukusasazeka kwe-phonon yedayimani. Njengezinto eziqinileyo, ifilimu yedayimani sisixhobo esihle sokugquma, esinokugqunywa phezu kwezixhobo zokusika kunye nee-molds ukuphucula kakhulu amandla azo omphezulu kunye nokwandisa ubomi bazo benkonzo. I-coefficient ephantsi ye-friction kunye ne-thermal conductivity ephezulu yeefilimu zedayimani ingasetyenziselwa ii-bearings zesantya esiphezulu zeenqwelomoya zamagama. I-coefficient ephezulu ye-thermal, i-coefficient ephantsi ye-friction kunye ne-transmittance elungileyo yefilimu yedayimani ikwenza ukuba isetyenziswe rhoqo njengezinto zokulinganisa ii-missile.
(2) Iimpawu zobushushu kunye nokusetyenziswa kwedayimani
Kule mihla, ukuhanjiswa kobushushu kwefilimu yedayimani yokwenziwa kusondele kakhulu kuleyo yedayimani yendalo. Ngenxa yokuhanjiswa kwayo kobushushu okuphezulu kunye nokumelana okuphezulu kombane, idayimani ingasetyenziswa njengomaleko wokukhusela we-substrate yesekethe edibeneyo, kunye nomaleko wokukhusela oqhuba ubushushu we-laser eziqinileyo. Ukongeza, ukuhanjiswa kobushushu okuphezulu kwedayimani, umthamo omncinci wobushushu, ingakumbi kumaqondo obushushu aphezulu xa isiphumo sokusasazwa kobushushu sibalulekile, sisixhobo esihle kakhulu sokucoca ubushushu. Ngophuhliso lwetekhnoloji yokubeka ifilimu yedayimani ethambileyo yokuqhuba ubushushu ephezulu, yenze ukusetyenziswa kokufakwa kobushushu kwedayimani ethambileyo kwi-laser ezinamandla aphezulu, izixhobo ze-microwave kunye neesekethe ezidibeneyo kwaba yinyani.
Nangona kunjalo, iimpawu zeefilimu zedayimani zokwenziwa zahluka kakhulu ngenxa yeenkqubo ezahlukeneyo zokulungiselela. Umzekelo, iimpawu zokuthutha ubushushu, ezibonakaliswa kakhulu ngumahluko omkhulu kwi-thermal diffusivity kunye ne-thermal conductivity. Ukongeza, ifilimu yedayimani yokwenziwa ibonisa i-anisotropy enamandla, kwaye i-thermal conductivity yobukhulu befilimu efanayo ehambelana nomphezulu wefilimu ngokucacileyo incinci kunobo bume obuthe nkqo kumphezulu wefilimu. Ezi zibangelwa ziiparameter zolawulo ezahlukeneyo kwinkqubo yokwenza ifilimu. Kuyabonakala ukuba inkqubo yokulungiselela iifilimu ezibhityileyo zedayimani kufuneka iphuculwe ngakumbi ukuze ukusebenza kwayo okuhle kusetyenziswe ngokubanzi.
