Ukwaleka

TEHRAN, 31 Agasti (MNA) - Abaphandi abavela kwiYunivesithi yeSayensi kunye neTekhnoloji i-MISiS (NUST MISiS) baye baqulunqa ubuchule obukhethekileyo bokusebenzisa iingubo zokukhusela kumacandelo abalulekileyo kunye neengxenye zobuchwepheshe zanamhlanje.
Izazinzulu ezivela kwiYunivesithi yaseRashiya i-MISIS (NUST MISIS) zibanga ukuba imvelaphi yetekhnoloji yabo ilele ekudibaniseni iingenelo zeendlela ezintathu zokubeka ezisekelwe kwimigaqo yomzimba eyahlukeneyo kumjikelo omnye wobugcisa wokufunxa. Ngokusebenzisa ezi ndlela, bafumana iingubo ezininzi ezinomgangatho ophezulu wokushisa ukushisa, ukuxhathisa ukugqoka kunye nokumelana nokubola, iingxelo zeSputnik.
Ngokutsho kwabaphandi, isakhiwo sokuqala sokugquma okubangelwa kubangele ukuphuculwa kwe-1.5-fold in corrosion resistance and high-temperature oxidation xa kuthelekiswa nezisombululo ezikhoyo. Iziphumo zabo zapapashwa kwi-International Journal yeCeramics.
"Ngokokuqala ngqa, i-electrode ekhuselayo esekelwe kwi-chromium carbide kunye ne-binder ye-NiAl (Cr3C2-NiAl) ifunyenwe ngokuphunyezwa ngokulandelelana kwe-vacuum electrospark alloying (VES), i-pulsed cathode-arc evaporation (IPCAE) kunye ne-magnetron sputtering ( NKSK). ) yenziwa kwinto enye. I-coating ine-compositional microstructure, eyenza kube lula ukudibanisa imiphumo enenzuzo yazo zonke iindlela ezintathu, "utshilo uFilipu, iNtloko yeLabhoratri "I-Innatural Diagnostics of Structural Transformation" kwi-MISiS-ISMAN Scientific Centre. Imfundo yaseKiryukhantsev-Korneev ayiboniswanga.
Ngokutsho kwakhe, baqale baphatha umphezulu kunye ne-VESA ukuhambisa izinto ezivela kwi-Cr3C2-NiAl ye-ceramic electrode ukuya kwi-substrate, iqinisekisa amandla aphezulu okubambelela phakathi kwengubo kunye ne-substrate.
Kwinqanaba elilandelayo, ngexesha le-pulsed cathode-arc evaporation (PCA), ii-ion ezisuka kwi-cathode zigcwalisa iziphene kumaleko wokuqala, iintanda ze-latching kwaye zenze i-denser kunye ne-uniform layer ene-corrosion resistance resistance.
Kwinqanaba lokugqibela, ukuhamba kwee-athom kwenziwa yimagnetron sputtering (MS) ukulinganisa i-topography yomphezulu. Ngenxa yoko, kuye kwenziwe umaleko oshinyeneyo omelana nobushushu, othintela ukusasazwa kweoksijini kwindawo enobundlobongela.
"Ukusebenzisa i-microscopy ye-electron yokudlulisa ukufundisisa isakhiwo somaleko ngamnye, sifumene iziphumo ezimbini zokukhusela: ukunyuka komthamo wokuthwala umthwalo ngenxa yomgangatho wokuqala we-VESA kunye nokulungiswa kweziphene ngokusetyenziswa kwemigangatho emibini elandelayo. Ngoko ke, sifumene i-coating-layer-three, ukuchasana kwayo kwi-corrosion kunye ne-high-temperature oxidation kwi-media ye-liquid kunye ne-gaseous iphindwe kabini kunye nesiqingatha ngaphezu kwe-coating yesiseko. Ayizukuba sisibaxo ukuba sisiphumo esibalulekileyo, utshilo uKiryukhantsev-Korneev.
Izazinzulu ziqikelela ukuba i-coating iyakwandisa ubomi kunye nokusebenza kwezinto ezibalulekileyo ze-injini, iimpompo zokuhambisa amafutha kunye nezinye izinto ezixhomekeke ekugugile kunye nokudleka.
Iziko lezeNzululwazi kunye neMfundo yeZiko lezeNzululwazi ngokuZisasaza kwi-High-Temperature Synthesis (i-SHS Centre), ekhokelwa nguNjingalwazi Evgeny Levashov, idibanisa izazinzulu ezivela kwi-NUST MISiS kunye ne-Institute of Structural Macrodynamics kunye neSayensi yezinto. AM Merzhanov Russian Academy of Sciences (ISMAN). Kwixesha elizayo elingekude, iqela lophando liceba ukwandisa ukusetyenziswa kobuchule obudibeneyo bokuphucula i-alloys ekwazi ukumelana nobushushu be-titanium kunye ne-nickel kwishishini leenqwelomoya.
