FeCrAl AlloyFoil/ Strip Coil 0.05mm Hukobvu hweMetallic Huchi Substrates

Iyo yakakwira aluminium yemukati, pamwe neyakakura chromium yemukati inoita kuti tembiricha yekuyera iwedzere kusvika 1425 C (2600F);Pasi pemusoro wemusoro wekudzivirira kupisa, izviFeCrAl alloys inofananidzwa neanowanzo shandiswa Fe uye Ni base alloys.Sezvinoonekwa kubva patafura iyo, iyoFeCrAl alloys ane zvivakwa zvepamusoro kana zvichienzaniswa nemamwe alloys munzvimbo zhinji.

Izvo zvinofanirwa kucherechedzwa kuti, panguva yekuchinjisa tembiricha mamiriro, iyo yttrium yekuwedzera kune AF alloy iyo inozivikanwawo seFecralloys alloys, inovandudza kuomerera kweiyo inodzivirira oxide, zvichiita kuti hupenyu hwebasa hwezvikamu muAF alloy hurebe kupfuura iyo A-1 giredhi.

Fe-Cr-Al alloy waya dzakagadzirwa nesimbi chromium aluminium base alloys ine zvidiki zvezvinoita zvinhu zvakaita seyttrium uye zirconium uye inogadzirwa nekunyungudika, kukungurutswa kwesimbi, kuforoma, kudhirowa, kudhirowa, kurapwa kwepamusoro, kuyedza kudzora kuyedza, nezvimwe.
Fe-Cr-Al waya yakaumbwa nenzira yekumhanyisa otomatiki yekutonhodza muchina iyo simba remagetsi rinodzorwa nekombuta, inowanikwa sewaya uye ribhoni(strip).

Zvimiro uye zvakanakira
1. Yakakwirira uchishandisa tembiricha, iyo yakanyanya kushandisa tembiricha inogona kusvika 1400C (0Cr21A16Nb, 0Cr27A17Mo2, nezvimwewo)
2. Yakaderera tembiricha coefficient yekupikisa
3. Kuderera kwekuwedzera kwekushisa kwekuwedzera kwehuwandu kupfuura Ni-base super-alloys.
4. High magetsi resistivity
5. Kuramba kwakanaka kwekuora pasi pekushisa kwepamusoro, kunyanya pasi pemhepo ine sulfides
6. Mutoro wepamusoro wepamusoro
7. Creep-resistant
8. Mutengo wepasi mbishi-material, Lower density uye mutengo wakachipa zvichienzaniswa newaya yeNichrome.
9. Superior oxidation resistance pa800-1300ºC
10. Hupenyu hurefu hwebasa

Kuumbwa kwe metastable alumina phases nekuda kweiyo oxidation yekutengeseranaFeCrAl alloywaya (0.5 mm ukobvu) panguva dzakasiyana tembiricha uye nguva nguva yakaongororwa.Samples aive isothermally oxidised mumhepo achishandisa thermogravimetric analyzer (TGA).Iyo morphology yemasampuli ane oxidised yakaongororwa pachishandiswa Electronic Scanning Electron Microscope (ESEM) uye X-ray pamusoro pekuongororwa kwepamusoro kwakaitwa pachishandiswa Energy Dispersive X-Ray (EDX) analyzer.Iyo nzira yeX-Ray Diffraction (XRD) yakashandiswa kuratidza chikamu chekukura kweoxide.Chidzidzo chese chakaratidza kuti zvaigoneka kukura yakakwirira-yepamusoro nzvimbo gamma alumina paneFeCrAl alloypawaya kana yaiswa oxidised kupfuura 800°C kwemaawa akati wandei.
