Waa maxay dahaarka isha uumiga iska caabbinta?

Dahaarka isha uumi-baxa iska caabbinta waa hab dahaarka uumi-baxa oo aasaasi ah. "Umi-baxa" waxaa loola jeedaa hab diyaarin filim khafiif ah oo walxaha dahaarka ee ku jira qolka faakuumka la kululeeyo oo la uumi-baxo, si atamka ama molecules-ka walxaha ay u uumi-baxaan oo ay uga baxsadaan dusha sare, iyagoo samaynaya ifafaale socodka uumi-baxa ah, oo ka dhaca dusha sare ee substrate-ka ama substrate-ka, ugu dambayntiina la isku ururiyo si loo sameeyo filim adag.

Habka loogu yeero dahaarka isha uumiga iska caabbinta waa in la isticmaalo tantalum, molybdenum, tungsten iyo biraha kale ee dhalaalaya ee aadka u sarreeya si loo sameeyo qaab ku habboon oo ah isha uumiga, kaas oo lagu shubay agab la uumi bixinayo, hawada u oggolaanaysa inay dhex marto, si toos ah u kululeyso oo u uumi bixinayo agabka uumiga leh, ama walxaha la uumi bixinayo lagu rido alumina, beryllium oxide iyo walxo kale oo loogu talagalay kuleylinta iyo uumiga dadban. Kani waa habka uumi bixinta kululaynta iska caabbinta.

TheMashiinka daahan uumi-baxa vacuumKululeeyaha iska caabbinta ayaa leh faa'iidooyinka qaab-dhismeedka fudud, kharash yar iyo isticmaal la isku halleyn karo. Waxaa loo isticmaali karaa dahaarka uumiga ee walxaha leh dhibic dhalaal yar, gaar ahaan wax soo saarka ballaaran oo leh shuruudo hooseeya oo tayada dahaarka ah. Ilaa hadda, waxaa jira tiro badan oo habab dahaar ah oo kululaynta iyo uumiga ah oo loo isticmaalo soo saarista muraayadaha aluminiumka ah.

Qasaarooyinka habka dahaarka uumiga isha uumiga ee iska caabbinta ayaa ah in heerkulka ugu badan ee lagu gaari karo kuleylintu uu xaddidan yahay, cimriga adeegga kuleyliyuhuna uu gaaban yahay. Sannadihii ugu dambeeyay, si loo hagaajiyo cimriga isha uumiga ee iska caabbinta, warshadda qalabka ayaa qaadatay walxaha dhoobada ah ee gudbiya oo ay samaysay boron nitride oo cimri dheer leh sida isha uumiga. Sida laga soo xigtay warbixin shati oo laga soo saaray Japan, waxay isticmaali kartaa agab ka kooban 20% ~ 30% boron nitride iyo agabyo iska caabbin ah oo lagu qasi karo si looga sameeyo isha uumiga (lagu shubi karo), oo dusha sarena lagu dahaadho lakab zirconium ah oo ka kooban 62% ~ 82%, inta soo hartayna waa agabyo isku-darka zirconium-silicon.
