FeCrAl AlloyFoil/ Strip Coil 0.05mm mānoanoa no nā mea hoʻoheheʻe meli metala

ʻO ka maʻiʻo alumini kiʻekiʻe, i hui pū ʻia me ka maʻi chromium kiʻekiʻe e hoʻonui ai ka mahana scaling a hiki i 1425 C (2600F);Ma lalo o ke poʻomanaʻo wela wela, kēiaFeCrAl huilaHoʻohālikelike ʻia nā s me nā mea hoʻohana maʻamau ʻo Fe a me Ni.E like me ka mea i ʻike ʻia ma ia papa ʻaina, ʻo kaFeCrAl huilas loaʻa nā waiwai ʻoi aku ka maikaʻi i ka hoʻohālikelike ʻia me nā mea hao ʻē aʻe i ka hapa nui o nā kaiapuni.

Pono e hoʻomaopopo ʻia, i ka wā e hoʻololi ai i nā kūlana wela, ʻo ka hoʻohui ʻana o ka yttrium i ka alloy AF i ʻike ʻia ʻo Fecralloys alloys, e hoʻomaikaʻi i ka pili ʻana o ka oxide pale, e ʻoi aku ka lōʻihi o ke ola o nā mea i loko o ka alloy AF ma mua o ko ka Papa A-1.

Hana ʻia nā uea Fe-Cr-Al i ka hao chromium aluminum base alloys i loaʻa nā mea liʻiliʻi o nā mea reactive e like me ka yttrium a me ka zirconium a hana ʻia e ka hoʻoheheʻe ʻana, ka ʻōwili kila, forging, annealing, drawing, surface treatment, resistance control test, etc.
Ua hana ʻia ka uea Fe-Cr-Al e ka mīkini hoʻoluʻu ʻokoʻa kiʻekiʻe e hoʻomalu ʻia ai ka mana mana e ke kamepiula, loaʻa iā lākou ma ke ʻano he uea a me ka lipine.

Nā hiʻohiʻona a me nā pono
1. ʻO ke kiʻekiʻe e hoʻohana ana i ka mahana, hiki ke kiʻekiʻe ka hoʻohana ʻana i ka mahana i 1400C (0Cr21A16Nb, 0Cr27A17Mo2, etc.)
2. Haʻahaʻa wela coefficient o ke kū'ē
3. Haʻahaʻa haʻahaʻa thermal hoʻonui coefficient ma mua o ka Ni-base super-alloys.
4. Kiʻekiʻe uila resistivity
5. ʻO ke kūpaʻa ʻino maikaʻi ma lalo o ka wela kiʻekiʻe, ʻoi aku ma lalo o ka lewa i loaʻa nā sulfide
6. Haawe ili kiʻekiʻe
7. ʻAʻole hiki ke kolo
8. Haʻahaʻa haʻahaʻa kumu kumu kūʻai, haʻahaʻa haʻahaʻa a me ke kumu kūʻai liʻiliʻi i hoʻohālikelike ʻia me ka uea Nichrome.
9. ʻOi aku ka maikaʻi o ka pale ʻana i ka oxidation ma 800-1300ºC
10. Ola lōʻihi

ʻO ka hoʻokumu ʻana i nā ʻāpana alumina metastable ma muli o ka oxidation o ke kālepaFeCrAl huilaua nānā ʻia nā uea (0.5 mm mānoanoa) i nā mahana like ʻole a me nā manawa.Ua hoʻokahe ʻia nā laʻana i ka ea me ka hoʻohana ʻana i ka thermogravimetric analyzer (TGA).Ua kālailai ʻia ka morphology o nā laʻana oxidised me ka Electronic Scanning Electron Microscope (ESEM) a me ka X-ray ma ka nānā ʻana i ka ʻili me ka hoʻohana ʻana i ka Energy Dispersive X-Ray (EDX).Ua hoʻohana ʻia ke ʻano o ka X-Ray Diffraction (XRD) e ʻike i ke ʻano o ka ulu ʻana o ka oxide.Ua hōʻike ka haʻawina holoʻokoʻa i hiki ke ulu i kahi kiʻekiʻe o ka gamma alumina ma kaFeCrAl huilaili uea i ka isothermally oxidised ma luna o 800°C no kekahi mau hola.
