FeCrAl chiwanikwaKoiri yeFoil/Strip Coil 0.05mm Ukobvu hweMetallic Honeycomb Substrates

Kuwanda kwearuminiyamu, pamwe chete nekuwedzera kwechromium, kunoita kuti tembiricha yekukura iwedzere kusvika pa1425 C (2600F); Pasi pemusoro wenyaya, kudzivirira kupisa, izviFeCrAl chiwanikwas dzinoenzaniswa neFe neNi base alloys dzinoshandiswa zvakanyanya. Sezvatinoona kubva patafura iyoyo,FeCrAl chiwanikwas dzine hunhu hwakanaka kana tichienzanisa nedzimwe alloys munzvimbo zhinji.

Zvinofanira kucherechedzwa kuti, panguva yekuchinjana kwemamiriro ekupisa, kuwedzera kwe yttrium kune AF alloy iyo inozivikanwawo seFecralloys alloys, kunovandudza kunamira kwe protective oxide, zvichiita kuti hupenyu hwekushanda hwezvikamu zviri muAF alloy huve hwakareba kupfuura hweA-1 grade.

Waya dzeFe-Cr-Al alloy dzakagadzirwa nesimbi chromium aluminum base alloys dzine zvinhu zvishoma zvinogadzirisa zvakaita seyttrium nezirconium uye zvinogadzirwa nekunyungudutsa, kutenderedza simbi, kugadzira, kupinza, kudhirowa, kurapwa pamusoro, bvunzo yekudzora kusimba, nezvimwewo.
Waya yeFe-Cr-Al yakagadzirwa nemuchina wekutonhodza unomhanya otomatiki uyo simba rayo rinodzorwa nekombuta, inowanikwa sewaya neribhoni (strip).

Zvimiro uye zvakanakira
1. Tembiricha yepamusoro yekushandisa, tembiricha yepamusoro yekushandisa inogona kusvika 1400C (0Cr21A16Nb, 0Cr27A17Mo2, nezvimwewo)
2. Kudzivirira kupisa kwakaderera
3. Kuwanda kwekuwedzera kwekupisa kwakaderera kupfuura maNi-base super-alloys.
4. Kudzivirira kwemagetsi kwakanyanya
5. Kudzivirira ngura zvakanaka kana tembiricha yakakwira, kunyanya pasi pemhepo ine sulfides
6. Mutoro wepamusoro wepamusoro
7. Inodzivirira kukambaira
8. Mutengo wakaderera wezvinhu zvakagadziriswa, Kuwanda kwakaderera uye mutengo wakaderera kana tichienzanisa newaya yeNichrome.
9. Kudzivirira kwakanyanya kwe oxidation pa 800-1300ºC
10. Hupenyu hurefu hwebasa

Kuumbwa kwezvikamu zvealumina zvinochinjika nekuda kwekuoxidation yezvigadzirwa zvekutengesaFeCrAl chiwanikwawaya (0.5 mm ukobvu) dzakaongororwa patembiricha dzakasiyana-siyana nenguva dzakasiyana. Samples dzakaiswa mumhepo ne isothermally oxidized uchishandisa thermogravimetric analyzer (TGA). Maumbirwo e samples dzakaiswa mu oxidized akaongororwa uchishandisa Electronic Scanning Electron Microscope (ESEM) uye X-ray pamusoro pe surface analyzer yakaitwa uchishandisa Energy Dispersive X-Ray (EDX) analyzer. Tekiniki yeX-Ray Diffraction (XRD) yakashandiswa kuratidza chikamu chekukura kwe oxide. Chidzidzo chose chakaratidza kuti zvaikwanisika kukura gamma alumina pamusoro pe high-surface area.FeCrAl chiwanikwapamusoro pewaya kana yaiswa oxidised inodziya pamusoro pe800°C kwemaawa akati wandei.
