FeCrAl AlloyFoil/ Strip Coil 0.05mm Botenya ba Metallic Honeycomb Substrates

Lintho tse phahameng tsa aluminium, hammoho le lihlahisoa tse phahameng tsa chromium li etsa hore mocheso oa sekhahla o eketsehe ho fihlela ho 1425 C (2600F); Tlas'a sehlooho sa ho hanyetsa mocheso, tsenaMotsoako oa FeCrAls li bapisoa le li-alloys tse sebelisoang hangata tsa Fe le Ni. Joalokaha ho ka bonoa tafoleng eo, theMotsoako oa FeCrAls na le thepa e phahameng ha e bapisoa le li-alloys tse ling libakeng tse ngata.

Hoa lokela ho hlokomeloa hore, nakong ea maemo a mocheso a fapa-fapaneng, tlatsetso ea yttrium ho motsoako oa AF, eo hape e tsejoang e le li-alloys tsa Fecralloys, e ntlafatsa ho khomarela oxide e sireletsang, e etsa hore bophelo ba tšebeletso ea likarolo tsa motsoako oa AF bo be telele ho feta ba Sehlopha sa A-1.

Fe-Cr-Al alloy lithapo li entsoe ka tšepe chromium aluminium base alloys e nang le lintho tse nyane tse sebetsang joalo ka yttrium le zirconium mme e hlahisoa ka ho qhibiliha, ho roala tšepe, ho forging, annealing, ho taka, kalafo ea holim'a metsi, tlhahlobo ea taolo ea ho hanyetsa, jj.
Fe-Cr-Al terata e ne e entsoe ka mochini o pholileng oa lebelo o phahameng oo matla a oona a laoloang ke komporo, li fumaneha joalo ka terata le ribone(strip).

Likarolo le melemo
1. Mocheso o phahameng oa ho sebelisa mocheso, boholo ba ho sebelisa mocheso o ka fihla ho 1400C (0Cr21A16Nb, 0Cr27A17Mo2, joalo-joalo)
2. Mocheso o fokolang oa mocheso oa ho hanyetsa
3. Coefficient e tlase ea ho atolosa mocheso ho feta Ni-base super-alloys.
4. High resistivity ea motlakase
5. Ho hanyetsa kutu e ntle tlas'a mocheso o phahameng, haholo-holo tlas'a sepakapaka se nang le sulfide
6. Mojaro o phahameng oa holim'a metsi
7. Ha e kenelle
8. Theko e tlase ea thepa e tala, boima bo tlase le theko e tlase ha e bapisoa le terata ea Nichrome.
9. Khanyetso e phahameng ea oxidation ho 800-1300ºC
10. Bophelo bo bolelele ba tšebeletso

Ho thehoa ha mekhahlelo ea metastable alumina ka lebaka la oxidation ea khoeboMotsoako oa FeCrAllithapo (0.5 mm botenya) dithempereichara tse fapa-fapaneng le linako nako e 'nile ea hlahlojoa. Lisampole li ne li entsoe ka oxidised ka isothermally moeeng li sebelisa tlhahlobo ea thermogravimetric (TGA). Morpholoji ea disampole tse nang le oxidised e ile ea hlahlobjoa ho sebelisoa Electronic Scanning Electron Microscope (ESEM) le X-ray holim'a tlhahlobo e entsoeng ka tšebeliso ea Analyzer ea Energy Dispersive X-Ray (EDX). Mokhoa oa X-Ray Diffraction (XRD) o ne o sebelisoa ho tšoaea karolo ea kholo ea oxide. Phuputso eohle e bontšitse hore ho ne ho ka khoneha ho hōlisa sebaka se phahameng sa gamma alumina holim'aMotsoako oa FeCrAlholim'a terata ha isothermally oxidised ka holimo 800 ° C ka lihora tse 'maloa.
