I-Fe-Cr-Al alloy yombane yokumelana nobushushu

Inkcazo
Iingcingo ze-Fe-Cr-Al zenzelwe ii-alloy ze-aluminium zesinyithi ze-chromium eziqulathe ubungakanani obuncinci bezinto ezisabelayo ezifana ne-yttrium kunye ne-zirconium kwaye ziveliswa ngokunyibilikisa, ukuqengqeleka kwentsimbi, ukubumba, ukutsalwa, unyango lomphezulu, uvavanyo lokulawula ukumelana, njl.

Umxholo ophezulu we-aluminiyamu, xa udibene nomxholo ophezulu we-chromium, uvumela ubushushu bokulinganisa bufikelele kwi-1425ºC (2600ºF);

Ucingo lwe-Fe-Cr-Al lwenziwe ngomatshini wokupholisa ozenzekelayo okhawulezayo apho amandla ombane alawulwa yikhompyutha, afumaneka njengocingo kunye neribhoni (umcu).

Iifom zemveliso kunye nobungakanani bayo

Ucingo olujikelezayo
Ezinye iisayizi eziyi-0.010-12 mm (0.00039-0.472 intshi) ziyafumaneka xa uzicelile.

Iribhoni (ucingo olusicaba)
Ubukhulu: 0.023-0.8 mm (0.0009-0.031 intshi)
Ububanzi: 0.038-4 mm (0.0015-0.157 intshi)
Ubungakanani/ubukhulu bomlinganiselo max 60, kuxhomekeke kwi-alloy kunye nokunyamezelana kwayo
Ezinye iisayizi ziyafumaneka xa ziceliwe.

Intambo yokufudumeza yombane enokuchasana nayo ineempawu ezinamandla ze-antioxidant, kodwa iintlobo ngeentlobo zeegesi ezikwii-oven ezifana nomoya, ikhabhoni, isalfure, ihydrogen kunye nomoya we-nitrogen, zisenempembelelo ethile kuyo.

Nangona ezi ntambo zokufudumeza zonke ziye zanyangwa nge-antioxidant, ukuthuthwa, ukujijwa, ukufakwa kunye nezinye iinkqubo ziya kubangela umonakalo kwinqanaba elithile kwaye zinciphise ubomi benkonzo yazo.

Ukuze kwandiswe ubomi benkonzo, abathengi kufuneka benze unyango lwangaphambi kokusetyenziswa kwe-oxidation. Le ndlela kukufudumeza izinto ze-alloy ezifakwe ngokupheleleyo emoyeni owomileyo ukuya kubushushu (obuphantsi kwe-100-200C kunobushushu bayo obuphezulu usebenzisa ubushushu), ukugcinwa kobushushu iiyure ezi-5 ukuya kwezili-10, emva koko ziphole kancinci nge-oven.
