TEHRAN, 31 August (MNA) - Ofufuza ochokera ku yunivesite ya Science and Technology MISiS (NUST MISiS) apanga njira yapadera yogwiritsira ntchito zokutira zotetezera ku zigawo zofunika kwambiri ndi mbali zamakono zamakono.
Asayansi ku Russian University MISIS (NUST MISIS) amanena kuti chiyambi cha luso lawo lagona kaphatikizidwe ubwino wa njira mafunsidwe atatu zochokera mfundo za thupi osiyana mkombero vakuyumu imodzi luso. Pogwiritsa ntchito njirazi, adapeza zokutira zamitundu yambiri ndi kukana kutentha kwakukulu, kukana kuvala ndi kukana kwa dzimbiri, Sputnik malipoti.
Malinga ndi ochita kafukufukuwo, mawonekedwe oyambirira a zokutira zomwe zachitikazo zinapangitsa kuti pakhale kusintha kwa 1.5-fold incorrosion resistance and high-temperature oxidation poyerekeza ndi mayankho omwe alipo. Zotsatira zawo zidasindikizidwa mu International Journal of Ceramics.
"Kwa nthawi yoyamba, zokutira zoteteza za elekitirodi zochokera ku chromium carbide ndi binder NiAl (Cr3C2-NiAl) zidapezedwa ndikukhazikitsa motsatizana kwa vacuum electrospark alloying (VES), pulsed cathode-arc evaporation (IPCAE) ndi magnetron sputtering ( MS). ) imachitidwa pa chinthu chimodzi. Chophimbacho chimakhala ndi microstructure yopangidwa, yomwe imapangitsa kuti zitheke kuphatikizira zopindulitsa za njira zonse zitatu, "anatero Philip, Mtsogoleri wa Laboratory "Innatural Diagnostics of Structural Transformations" ku MISiS-ISMAN Scientific Center. Maphunziro a Kiryukhantsev-Korneev sanasonyezedwe.
Malinga ndi iye, iwo anayamba kuchitira pamwamba ndi VESA kusamutsa zinthu Cr3C2-NiAl ceramic electrode ku gawo lapansi, kuonetsetsa kuti mkulu adhesion mphamvu pakati zokutira ndi gawo lapansi.
Pa gawo lotsatira, panthawi ya pulsed cathode-arc evaporation (PCA), ma ions ochokera ku cathode amadzaza zolakwika mu gawo loyamba, kutsekeka ming'alu ndikupanga wosanjikiza wandiweyani komanso wofanana kwambiri wokhala ndi kukana dzimbiri.
Pamapeto pake, kutuluka kwa ma atomu kumapangidwa ndi magnetron sputtering (MS) kuti agwirizane ndi malo apamwamba. Chotsatira chake, pamwamba pake pamakhala wosanjikiza wosamva kutentha, womwe umalepheretsa kufalikira kwa okosijeni kuchokera kumalo ankhanza.
"Pogwiritsa ntchito ma microscopy a ma elekitironi opatsirana kuti tiphunzire kapangidwe ka gawo lililonse, tidapeza zodzitchinjiriza ziwiri: kuchuluka kwa mphamvu yonyamula katundu chifukwa cha gawo loyamba la VESA ndikukonza zolakwika ndikugwiritsa ntchito zigawo ziwiri zotsatirazi. Choncho, tapeza zokutira zosanjikiza zitatu, kukana kwa dzimbiri ndi mkulu-kutentha oxidation mu madzi ndi mpweya TV ndi nthawi imodzi ndi theka kuposa ❖ kuyanika m'munsi. Sizingakhale kukokomeza kunena kuti izi ndi zotsatira zofunika, "adatero Kiryukhantsev-Korneev.
Asayansi akuyerekeza kuti zokutirazi ziwonjezera moyo ndi magwiridwe antchito a zida zofunika kwambiri za injini, mapampu otengera mafuta ndi zinthu zina zomwe zimatha kuvala komanso dzimbiri.
The Scientific and Educational Center for Self-Propagating High-Temperature Synthesis (SHS Center), motsogozedwa ndi Pulofesa Evgeny Levashov, amagwirizanitsa asayansi ochokera ku NUST MISiS ndi Institute of Structural Macrodynamics and Materials Science. AM Merzhanov Russian Academy of Sciences (ISMAN). Posachedwapa, gulu lofufuza likukonzekera kukulitsa kugwiritsa ntchito njira yophatikizirapo kuti apititse patsogolo ma alloys osagwira kutentha a titaniyamu ndi faifi tambala pamakampani opanga ndege.
