FeCrAl alloy inowanikwa zvakanyanya munzvimbo dzinodziya magetsi.

Nekuti ine zvayakanakira zvakawanda, hongu ine zvayaikanganisawo, ngatizvidzidzei.

Zvakanakira:

1, Tembiricha yekushandisa mumhepo yakakwira.

Tembiricha yepamusoro yebasa reHRE alloy mu iron-chromium-aluminium electrothermal alloy inogona kusvika 1400℃, nepo yeCr20Ni80 alloy mu nickel-chromium electrothermal alloy inogona kusvika 1200℃.

2, Hupenyu hwebasa refu

Pasi pekupisa kwakafanana kwemhepo, hupenyu hwechinhu cheFe-Cr-Al hunogona kureba ka2-4 kupfuura hwechinhu cheNi-Cr.

3, Mutoro wepamusoro wepamusoro

Nekuti Fe-Cr-Al alloy inobvumira tembiricha yepamusoro yebasa uye hupenyu hurefu hwebasa, mutoro wepamusoro wechikamu unogona kunge wakakwira, izvo zvisingaite kuti tembiricha ikwire nekukurumidza, asiwo zvinochengetedza zvinhu zve alloy.

4, Kudzivirira kwakanaka kwe oxidation

Chimiro cheAl2O3 oxide film chinoumbwa pamusoro peFe-Cr-Al alloy chakabatana, chine kubatana kwakanaka nesubstrate, uye hazvisi nyore kukonzera kusvibiswa nekuda kwekupararira. Pamusoro pezvo, Al2O3 ine resistivity yakanyanya uye melting point, izvo zvinoratidza kuti Al2O3 oxide film ine resistance yakanaka kwazvo ye oxidation. Resistance ye carburizing iri naniwo pane Cr2O3 inoumbwa pamusoro peNi-Cr alloy.

5, Diki chaiyo giravhiti

Huremu hweFe-Cr-Al alloy hwakanyanya kuderera pane hweNi-Cr alloy, zvinoreva kuti zvinodhura kushandisa Fe-Cr-Al alloy pane Ni-Cr alloy pakugadzira zvinhu zvakafanana.

6, Kudzivirira kwakanyanya

Kudzivirira kweFe-Cr-Al alloy kwakakwira kupfuura kweNi-Cr alloy, saka zvinhu zvakakura zvealloy zvinogona kusarudzwa pakugadzira zvikamu, izvo zvinobatsira kuwedzera hupenyu hwebasa rezvikamu, kunyanya kune waya dzakapfava dzealloy. Kana zvinhu zvine zvirevo zvakafanana zvikasarudzwa, kudzivirira kwakakwira, zvinhu zvakawanda zvichachengetwa, uye nzvimbo yezvikamu muchoto ichave diki. Pamusoro pezvo, kudzivirira kweFe-Cr-Al alloy hakukanganisi zvakanyanya nekushanda kunotonhora uye kurapwa kwekupisa kupfuura kweNi-Cr alloy.

7, Kudzivirira kwakanaka kwesarufa

Simbi, chromium nearuminiyamu zvinodzivirira ngura zvakanaka kumhepo ine sarufa uye kana pamusoro payo pakasvibiswa nezvinhu zvine sarufa, nepo nickel nechromium zvichizoparadzwa zvakanyanya.

8, Mutengo wakachipa

Iron-chromium-aluminium yakachipa zvikuru pane nickel-chromium nekuti haina nickel shoma.

Zvakashata:

1, Simba rakaderera pakupisa kwakanyanya

Kupfava kwayo kunowedzera nekuwedzera kwekupisa. Kana tembiricha iri pamusoro pe1000℃, chinhu chacho chinotambanuka zvishoma nezvishoma nekuda kwehuremu hwacho, izvo zvinozokonzera kuchinja kwechinhu chacho.

2, Zviri nyore kuti uwane brittleness yakakura

Mushure mekushandiswa pakupisa kwakanyanya kwenguva yakareba uye kutonhorerwa muchoto, inoomarara sezvo tsanga dzichikura, uye haigone kukotama kana yatonhora.

3, Magineti

Fecral alloy ichave isina simba remagineti pamusoro pe600°C.

4, Kuramba ngura hakuna kusimba pane nicr alloy.

Kana muine rumwe ruzivo, gamuchirai kuti mutaure nesu.

Tinogona kugadzira zvigadzirwa zvefecral alloy zvinosvika matani mazana maviri, kana muchida, ndapota inzwa wakasununguka kutibata.
