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 electrode ku salaysan chromium carbide iyo binder NiAl (Cr3C2-NiAl) waxaa lagu helay fulinta isdaba jooga ah ee vacuum electrospark alloying (VES), pulsed cathode-arc evaporation (IPCAE) iyo magnetron sputtering (MS) waxaa lagu sameeyaa hal shay. ayuu yiri Philip, Madaxa Shaybaadhka "Cilmi-baadhista Dabiiciga ah ee Isbeddellada Dhismeedka" 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 qaabdhismeedka lakab kasta, waxaan helnay laba saameyn oo difaac ah: kororka awoodda culeyska sababtoo ah lakabka koowaad ee VESA iyo hagaajinta cilladaha iyadoo la adeegsanayo labada lakab ee soo socda in tani ay tahay 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.
