Tehran, 31 Lub Yim Hli (MNA) - Cov kws tshawb nrhiav los ntawm University of Science thiab technology misis) tau tsim cov txheej txheem tiv thaiv rau cov khoom tseem ceeb thiab cov khoom siv niaj hnub no.
Cov kws tshawb fawb los ntawm Lavxias tsev kawm ntawv MISIS) thov hais tias lub tshiab ntawm lawv txoj kev faib nyiaj ntawm peb lub tshuab nqus tsev nyob rau hauv ib lub voj voog sib txawv. Los ntawm kev thov cov hau kev no, lawv tau txais cov txheej txheej ntau nrog cov kub ua kom tiv taus kub, hnav tsis kam thiab corrosion tsis kam, cov ntaub ntawv tshaj tawm sputnik.
Raws li cov kws tshawb nrhiav, tus qauv qub ntawm cov txheej txheej tshwm sim hauv kev txhim kho hauv corrosion thiab kub oxidation piv rau cov kev daws teeb meem uas twb muaj lawm. Lawv cov txiaj ntsig tau tshaj tawm nyob rau hauv cov phau ntawv xov xwm thoob ntiaj teb ntawm Ceramics.
"Rau thawj zaug, kev tiv thaiv kev tiv thaiv ntawm hluav taws xob raws li cov khoom siv hluav taws xob (ves) thiab muaj peev xwm ua tau los ntawm ib qho khoom.) Ntawm peb txoj hauv kev, "Philis, lub taub hau ntawm chav kuaj" ntawm kev hloov pauv ntawm MISIS-ISAN Txoj kev kawm ntawm Kiryukhantsev-Korneev tsis tau qhia.
Raws li nws, lawv xub kho qhov chaw nrog Vesa hloov cov khoom los ntawm CR3C2-nial ceramic muaj zog ntawm txheej thiab lub substrate.
Nyob rau theem tom ntej, thaum pulsed cathode-arc evaporation (PCIA), ation los ntawm lub denser sau tsis xws luag thiab ntau yam kev sib tsoo txheej nrog high corrosion tsis kam.
Nyob rau theem kawg, kev ntws ntawm atoms yog tsim los ntawm magnetron sputtering (ms) rau qib kaum sab nrauv. Raws li qhov tshwm sim, txoj kev ua cua sov ntom ntom nti ua ke yog tsim, uas tiv thaiv lub diffusion ntawm oxygen ntawm kev txhoj puab ib puag ncig.
"Kev siv cov hluav taws xob electron tsom rau kev kawm cov qauv ntawm txhua txheej ua kua thiab cov khoom lag luam uas muaj peev xwm ua tau zoo li ntawm cov khoom siv thib ib. Nws yuav tsis yog qhov ua kom dhau los hais tias qhov no yog Ib qho txiaj ntsig tseem ceeb, "Said Keryukhantsev-Korneev.
Cov kws tshawb fawb kwv yees hais tias cov txheej yuav nce ntxiv lub neej thiab kev ua tau zoo ntawm cov twj tseem ceeb, roj hloov cov twj thiab lwm yam kev hnav khaub ncaws hnav thiab corrosion.
Lub chaw kawm txuj ci thiab kev kawm rau nws tus kheej hais txog kev kub siab (chaw kws tshawb fawb) Kuv yog Merzhanov Lavxias Tsev Kawm Txuj Ci ntawm Kev Tshawb Fawb (Isman). Nyob rau yav tom ntej ze, pab pawg tshawb fawb npaj los nthuav kev siv cov txheej txheem sib txuas ua ke kom txhim kho cov kev lag luam kub-des resistant alloys ntawm titanium thiab npib tsib xee rau lub dav hlau.
