Coating

TEHRAN, 31 Nyamavhuvhu (MNA) - Vatsvagiri kubva kuYunivhesiti yeSainzi neTekinoroji MISiS (NUST MISiS) vakagadzira nzira yakasarudzika yekushandisa machira ekudzivirira kune zvakakosha zvikamu uye zvikamu zvehunyanzvi hwemazuva ano.
Masayendisiti kubva kuRussian University MISIS (NUST MISIS) vanoti mavambo ehunyanzvi hwavo ari mukubatanidza zvakanakira nzira nhatu dzekuisa zvichienderana nemisimboti yemuviri yakasiyana mune imwe tekinoroji vacuum kutenderera. Nekushandisa nzira idzi, vakawana akawanda-layer coatings ane high heat resistance, kupfeka kusamira uye corrosion resistance, Sputnik inoshuma.
Maererano nevatsvakurudzi, chimiro chepakutanga chekuputira chinoguma chakakonzera kuvandudzwa kwe1.5-fold in corrosion resistance uye high-temperature oxidation kana ichienzaniswa nemhinduro dziripo. Mhedzisiro yavo yakaburitswa muInternational Journal yeCeramics.
"Kekutanga, chivharo chekudzivirira che electrode chakavakirwa pachromium carbide uye binder NiAl (Cr3C2-NiAl) yakawanikwa nekuteedzera kutevedzana kwevacuum electrospark alloying (VES), pulsed cathode-arc evaporation (IPCAE) uye magnetron sputtering ( MS). ) inoitwa pachinhu chimwe. Iyo yekuputira ine yakaumbwa microstructure, iyo inoita kuti zvikwanise kusanganisa zvinobatsira zvemaitiro ese matatu," akadaro Firipi, Musoro weLabhoritari "Innatural Diagnostics of Structural Transformations" paMISiS-ISMAN Scientific Center. Dzidzo yeKiryukhantsev-Korneev haina kuratidzwa.
Sekureva kwake, ivo vakatanga kubata kumeso neVESA kuendesa zvinhu kubva kuCr3C2-NiAl ceramic electrode kuenda kune substrate, kuve nechokwadi chepamusoro chekunamatira kusimba pakati pejasi uye substrate.
Pachinhanho chinotevera, panguva yepulsed cathode-arc evaporation (PCA), maion kubva mucathode anozadza kukanganisa muchikamu chekutanga, kutsemuka kwakatsemuka uye kugadzira denser uye yakawanda yunifomu layer ine yakakwira corrosion resistance.
Padanho rekupedzisira, kuyerera kwemaatomu kunoumbwa nemagnetron sputtering (MS) kuti aenzane nepamusoro petopography. Nekuda kweizvozvo, denderedzwa repamusoro rinodzivirira kupisa rinoumbwa, iro rinodzivirira kupararira kweokisijeni kubva munzvimbo ine hutsinye.
"Tichishandisa transmission electron microscopy kudzidza chimiro chega rega rega, takawana maitiro maviri ekudzivirira: kuwedzera kwekutakura mutoro nekuda kwechikamu chekutanga cheVESA uye kugadziriswa kwehurema nekushandiswa kwezvikamu zviviri zvinotevera. Naizvozvo, isu takawana matatu-layer coating, iyo inopikisa iyo kune ngura uye yakakwirira-tembiricha oxidation mumvura uye gaseous media imwe nehafu yakapetwa kupfuura iyo yepasi coating. Hazvingave zvekuwedzeredza kutaura kuti ichi chiitiko chakakosha, "akadaro Kiryukhantsev-Korneev.
Masayendisiti anofungidzira kuti kupfekedza kuchawedzera hupenyu uye kushanda kwezvinhu zvakakosha zveinjini, pombi dzekufambisa mafuta uye zvimwe zvinhu zviri pasi pekupfeka uye ngura.
Scientific and Educational Center for Self-Propagating High-Temperature Synthesis (SHS Center), inotungamirirwa naPurofesa Evgeny Levashov, inobatanidza masayendisiti kubva kuNUST MISiS uye Institute of Structural Macrodynamics uye Materials Science. AM Merzhanov Russian Academy yeSainzi (ISMAN). Munguva pfupi iri kutevera, boka rekutsvagisa rinoronga kuwedzera kushandiswa kweiyo yakasanganiswa nzira yekuvandudza kupisa-resistant alloys yetitanium uye nickel yeindasitiri yendege.
