I-alloy ye-FeCrAl ixhaphake kakhulu kwindawo yokufudumeza umbane.

Kuba ineengenelo ezininzi, ewe, ikwanazo nezingeloncedo, masiyifunde.

Izinto eziluncedo:

1,Ubushushu bokusetyenziswa kwiatmosfera buphezulu.

Ubushushu benkonzo enkulu ye-HRE ingxubevange yentsimbi-chromium-aluminiyam i-electrothermal alloy inokufikelela kwi-1400℃, ngelixa i-Cr20Ni80 ingxubevange kwi-nickel-chromium electrothermal alloy inokufikelela kwi-1200℃.

2, Ubomi benkonzo ende

Ngaphantsi kweqondo lokushisa eliphezulu elifanayo kwi-atmosphere, ubomi be-Fe-Cr-Al element bunokuba ngamaxesha angama-2-4 ubude kunobo be-Ni-Cr element.

3,Umthwalo ophezulu womphezulu

Ngenxa yokuba i-alloy ye-Fe-Cr-Al ivumela ubushushu benkonzo ephezulu kunye nobomi benkonzo ende, umthwalo wecandelo lomhlaba unokuba phezulu, ongenzi nje ukuba ubushushu bunyuke ngokukhawuleza, kodwa bubuye bugcine izixhobo ze-alloy.

I-4, ukuxhathisa okulungileyo kwe-oxidation

Isakhiwo sefilimu ye-Al2O3 ye-oxide eyenziwe phezu kwendawo ye-Fe-Cr-Al i-alloy i-compact, inokubambelela kakuhle kunye ne-substrate, kwaye akulula ukubangela ukungcola ngenxa yokusabalalisa. Ukongeza, i-Al2O3 inokumelana okuphezulu kunye nenqanaba lokunyibilika, elimisela ukuba ifilimu ye-Al2O3 oxide inokumelana ne-oxidation ebalaseleyo. Ukumelana ne-carburizing kukwangcono kune-Cr2O3 eyenziwe kumphezulu we-Ni-Cr alloy.

5,Ubunzima obuthile obuncinci

Ubunzima obuthile be-alloy ye-Fe-Cr-Al buncinci kune-alloy ye-Ni-Cr, oku kuthetha ukuba kunoqoqosho ngakumbi ukusebenzisa i-alloy ye-Fe-Cr-Al kune-alloy ye-Ni-Cr xa usenza amacandelo afanayo.

6, ukumelana okuphezulu

I-resistantivity ye-Fe-Cr-Al i-alloy iphezulu kune-alloy ye-Ni-Cr, ngoko ke izinto ezinkulu ze-alloy zinokukhethwa xa kuqulunqwa amacandelo, okunenzuzo yokwandisa ubomi benkonzo yamacandelo, ngokukodwa kwiintambo ze-alloy ezintle. Xa izixhobo ezineenkcazo ezifanayo zikhethiweyo, ukuphakama kwe-resistiveivity, izinto ezininzi ziya kugcinwa, kwaye indawo encinci yamacandelo kwisithando somlilo iya kuba. Ukongeza, i-resistiveivity ye-Fe-Cr-Al alloy ayichatshazelwa kangako ngumsebenzi obandayo kunye nobushushu bonyango kune-Ni-Cr alloy.

7,Ukumelana kakuhle nesalfure

I-iron, ichromium kunye ne-aluminiyam zikwazi ukumelana nokuhlwa okuhle kwi-atmosfera enesulfure naxa umphezulu womhlaba ungcoliswe zizinto ezinesulfure, ngelixa i-nickel kunye nechromium ziya kukhukuliswa ngokumandundu.

8,Ixabiso eliphantsi

I-Iron-chromium-aluminiyam inexabiso eliphantsi kunenickel-chromium kuba ayinayo nickel enqabileyo.

Izinto ezingeloncedo:

1,Amandla aphantsi kwiqondo lobushushu eliphezulu

Iplastiki yayo iyanda ngokunyuka kweqondo lokushisa. Xa iqondo lobushushu lingaphezulu kwe-1000℃, i-material iya kolula kancinci ngenxa yobunzima bayo, okuya kubangela ukuguqulwa kwento.

2,Kulula ukufumana ubuqhophololo obukhulu

Emva kokusetyenziswa kwiqondo lokushisa eliphezulu ixesha elide kwaye ipholile kwisithando somlilo, iba yi-brittle njengoko ingqolowa ikhula, kwaye ayikwazi ukugoba kwimeko ebandayo.

3, Magnetic

Ingxubevange ye-Fecral ayiyi kuba yimagnetic ngaphezu kwe-600 ° C.

I-4, ukuxhathisa i-Corrosion buthathaka kune-nicr alloy.

Ukuba unolwazi oluthe kratya, wamkelekile ukuba uxoxe nathi.

Sinokuvelisa malunga neetoni ezingama-200 zeemveliso ze-fecral alloy, ukuba ufuna, nceda ukhululeke ukudibana nathi.
