Dahaarka

TEHRAN, 31 Agoosto (MNA) - Cilmi-baarayaal ka socda Jaamacadda Sayniska iyo Teknolojiyada MSiS (NUST MASIS) waxay soo saareen farsamo gaar ah oo loogu talagalay daboolka ilaalinta qaybaha muhiimka ah iyo qaybaha tiknoolajiyada casriga ah.
Saynisyahano ka socda Jaamacadda Ruushka ee MISIS (NUST MISIS) ayaa sheeganaya in asalka tignoolajiyada ay ku jirto in la isku daro faa'iidooyinka saddex hab oo dhigaal ah oo ku salaysan mabaadi'da jireed ee kala duwan ee hal wareeg oo farsamo. Codsiga hababkan, waxay heleen lakabyo badan oo lakabyo leh oo leh caabbinta kulaylka sare, xirashada caabbinta iyo iska caabinta daxalka, Sputnik ayaa sheegaysa.
Sida laga soo xigtay cilmi-baarayaasha, qaabka asalka ah ee daahan ka soo baxa ayaa keenay 1.5-laab hagaajinta caabbinta daxalka iyo oksaydhka heerkulka sare marka loo eego xalalka jira. Natiijooyinkooda waxaa lagu daabacay Joornaalka Caalamiga ah ee Ceramics.
"Markii ugu horeysay, dahaarka difaaca ee korantada ku salaysan chromium carbide iyo binder NiAl (Cr3C2-NiAl) ayaa la helay iyada oo la fulinayo is-daba-joogga ah ee vacuum electrospark alloying (VES), uumiga cathode-arc (IPCAE) iyo magnetron sputtering ( MS). ) waxaa lagu sameeyaa hal shay. Dahaarku wuxuu leeyahay qaab-dhismeed yar oo ka kooban, kaas oo suurtogal ka dhigaya in la isku daro saameynta faa'iidada leh ee dhammaan saddexda waji, "ayuu yiri Philip, Madaxa Shaybaarka "Cilmi-baadhista Dabiiciga ah ee Isbeddellada Dhismaha" ee Xarunta Sayniska ee MISiS-ISMAN. Waxbarashada Kiryukhantsev-Korneev lama tilmaamay.
Sida laga soo xigtay isaga, waxay marka hore ku daaweeyeen dusha sare ee VESA si ay ugu wareejiyaan walxaha ka soo baxa Cr3C2-NiAl electrode dhoobada ah ee substrate, hubinta xoogga sare ee u dhexeeya daaha iyo substrate-ka.
Marxaladda xigta, inta lagu jiro uumiga cathode-arc (PCIA), ions ka soo baxa cathode waxay buuxiyaan cilladaha lakabka koowaad, dildilaaca oo samaynta lakab cufan iyo labis badan leh oo leh caabbinta daxalka sare.
Marxaladda ugu danbeysa, socodka atomyada waxaa sameysma magnetron sputtering (MS) si loo qiyaaso muuqaalka kore ee dusha sare. Natiijo ahaan, lakabka sare ee kulaylka cufan ayaa la sameeyay, kaas oo ka hortagaya faafinta ogsijiinta ee jawiga gardarrada ah.
"Isticmaalka gudbinta mikroskoobyada elektarooniga ah si aan u barano qaab dhismeedka lakab kasta, waxaan helnay laba saameyn oo ilaalin ah: kororka awoodda culeyska sababtoo ah lakabka koowaad ee VESA iyo hagaajinta cilladaha iyadoo la adeegsanayo labada lakab ee soo socda. Sidaa darteed, waxaan helnay daahan saddex-lakab ah, iska caabbinta taas oo ah daxalka iyo oksaydhka heerkulka sare ee dareeraha iyo gaasaska ayaa hal jeer iyo badh ka sarreeya kan salka hoose. Ma noqon doonto buunbuunin in la yiraahdo tani waa natiijo muhiim ah, "ayuu yiri Kiryukhantsev-Korneev.
Saynis yahanadu waxa ay qiyaaseen in dahaarka uu kordhin doono nolosha iyo waxqabadka qaybaha mishiinada muhiimka ah,matoorada wareejinta shidaalka iyo qaybaha kale ee ku xidhan xidhashada iyo daxalka labadaba.
Xarunta Sayniska iyo Waxbarashada ee Isku-Faafinta Heerkulka Sare (SHS Center), oo uu madax u yahay Professor Evgeny Levashov, ayaa mideeya saynisyahano ka socda NUST MISiS iyo Machadka Dhismaha Macrodynamics iyo Sayniska Qalabka. AM Merzhanov Akademiyada Sayniska Ruushka (ISMAN). Mustaqbalka dhow, kooxda cilmi-baaristu waxay qorsheynayaan inay ballaariyaan isticmaalka farsamada isku dhafan si loo hagaajiyo kuleyliyeyaasha kulaylka u adkaysta ee titanium iyo nikkel ee warshadaha diyaaradaha.
