Idayimani eyenziwe ngekhemikhali eyomeleleyo ineempawu ezikhethekileyo zoomatshini kunye nelastiki. Ubunzima, ubuninzi kunye ne-thermal conductivity yedayimani yizona ziphezulu phakathi kwezinto ezaziwayo. Idayimani nayo ineyona modulus iphezulu yokunwebeka kwayo nayiphi na imathiriyeli. I-coefficient of friction yefilimu yedayimani yi-0.05 kuphela. Ukongeza, idayimani ineyona conductivity iphezulu ye-thermal, eyanda ngaphezu kwesihlanu ukuba ifilimu yedayimane ilungiselelwe usebenzisa i-isotopi ecocekileyo yekhabhoni. Esona sizathu siphambili sokusebenzisa i-isotopes yekhabhoni ukulungisa idayimani kukunciphisa ukusasazeka kwe-phonon yedayimane. Njengesixhobo esinzima kakhulu, ifilimu yedayimane yinto efanelekileyo yokugqoka, enokuthi ifakwe kumphezulu wezixhobo zokusika kunye nokubumba ukuze kuphuculwe kakhulu amandla abo omhlaba kunye nokwandisa ubomi babo benkonzo. I-coefficient ephantsi ye-friction kunye ne-thermal conductivity ephezulu yeefilimu zedayimani zingasetyenziselwa iibheringi zesantya esiphezulu kwi-aviation yegama. I-thermal conductivity ephezulu, i-coefficient ephantsi ye-friction kunye nokuhanjiswa kokukhanya okulungileyo kwefilimu yedayimani nayo yenza ukuba isetyenziswe rhoqo njengempahla ye-fairing yemijukujelwa.
(2) IiPropati zeThermal kunye nezicelo zeDayimane
Kule mihla, i-thermal conductivity yefilimu yedayimani eyenziweyo isondele kakhulu kwidayimane yendalo. Ngenxa ye-thermal conductivity ephezulu kunye nokumelana nombane okuphezulu, idayimani ingasetyenziswa njengomaleko wokugquma we-substrate yesekethe edibeneyo, kunye nomaleko wokugquma we-thermal conductive we-laser-state eqinile. Ukongeza, i-diamond ephezulu ye-thermal conductivity, umthamo omncinci wobushushu, ngakumbi kumaqondo obushushu aphezulu xa impembelelo yokutshatyalaliswa kobushushu ibalulekile, yinto ebalaseleyo yokushisa ubushushu. Ngophuhliso lwetekhnoloji yedayimani ebhityileyo yokubeka ifilimu, yenze ukusetyenziswa kwedayimani ebhityileyo yokubeka ifilimu eshushu kwiilaser ezinamandla, izixhobo zemicrowave kunye neesekethe ezihlanganisiweyo zibe yinyani.
Nangona kunjalo, iipropati zeefilimu zedayimane ezenziweyo ziyahluka kakhulu ngenxa yeenkqubo ezahlukeneyo zokulungiselela. Ngokomzekelo, iipropati zokuthutha i-thermal, ezibonakaliswe ngokukodwa ngokungafani okukhulu kwi-thermal diffusivity kunye ne-thermal conductivity. Ukongeza, ifilimu yedayimani eyenziweyo ibonisa i-anisotropy eyomeleleyo, kwaye ukuqhutyelwa kwe-thermal yobukhulu befilimu obufanayo obunxusene nomphezulu wefilimu ngokucacileyo buncinci kunobume befilimu. Ezi zibangelwa iiparamitha zolawulo ezahlukeneyo kwinkqubo yokwenza ifilimu. Kunokubonwa ukuba inkqubo yokulungiselela iifilimu ezibhityileyo zedayimani kufuneka ziphuculwe ngakumbi ukuze kwenziwe ukusebenza kwayo okugqwesileyo kusetyenziswe ngokubanzi.
