I-5J1480 i-alloy echanekileyo 5J1480 superalloy Iron-nickel alloy Ngokwezinto ze-matrix, inokwahlulwa ibe yi-iron-based superalloy, i-nickel-based superalloy kunye ne-cobalt-based superalloy. Ngokwenkqubo yokulungiselela, inokohlulwa ibe yi-superalloy egogekileyo, ukuphosa i-superalloy kunye ne-powder metallurgy superalloy. Ngokwendlela yokomeleza, kukho uhlobo oluqinileyo lokuqinisa isisombululo, uhlobo lokuqinisa imvula, uhlobo lokuqinisa i-oxide kunye nohlobo lokomeleza ifayibha. Iialloyi zobushushu obuphezulu zisetyenziswa ikakhulu ekwenzeni izinto ezinobushushu obuphezulu obunje ngeeblawudi zeinjini yomoya, iintambo zesikhokelo, iidiski zeiturbine, iidiski zoxinzelelo oluphezulu kunye namagumbi okutsha omoya, iiinjini zolwandle kunye nezamashishini, kwaye zikwasetyenziswa ekwenzeni. yezithuthi zasemoyeni, iinjini zerokethi, izixhobo zenyukliya, izixhobo zepetrochemical kunye nokuguqulwa kwamalahle kunye nezinye izixhobo zokuguqula amandla.

ukusetyenziswa kwezinto eziphathekayo

I-5J1480 i-bimetal ye-thermal 5J1480 i-alloy echanekileyo 5J1480 i-superalloy iron-nickel alloy superalloy ibhekisela kuhlobo lwezinto zetsimbi ezisekelwe kwintsimbi, i-nickel kunye ne-cobalt, enokusebenza ixesha elide kwiqondo lokushisa eliphezulu ngaphezu kwe-600 ℃ naphantsi koxinzelelo oluthile; kwaye inamandla aphezulu aphezulu obushushu obuphezulu, ukuxhathisa okulungileyo kwe-oxidation kunye nokuxhathisa ukubola, ukusebenza kakuhle kokudinwa, ukuqina kwe-fracture kunye nezinye iimpawu ezibanzi. I-superalloy yisakhiwo esisodwa se-austenite, esinozinzo oluhle lwesakhiwo kunye nokuthembeka kwenkonzo kumaqondo okushisa ahlukeneyo.

Ngokusekelwe kwiimpawu zokusebenza ezingentla, kunye neqondo eliphezulu le-alloying ye-superalloys, eyaziwa nangokuthi "i-super alloys", yinto ebalulekileyo esetyenziswa ngokubanzi kwi-aviation, i-aerospace, i-petroleum, imboni yeekhemikhali, kunye neenqanawa. Ngokwezinto ze-matrix, i-superalloys ihlukaniswe kwi-iron-based, i-nickel-based, i-cobalt-based kunye nezinye ii-superalloys. Ubushushu benkonzo yentsimbi esekwe kwiqondo lobushushu obuphezulu bungafikelela kuphela kuma-750 ~ 780°C. Kwiindawo ezichasene nokushisa ezisetyenziselwa ukushisa okuphezulu, i-nickel-based based and refractory metal-based alloys isetyenziswa. I-nickel-based superalloys ithatha indawo ekhethekileyo kunye nebalulekileyo kwintsimi yonke ye-superalloys. Zisetyenziswa ngokubanzi ukwenza ezona ndawo zishushu zeenjini zejethi yenqwelomoya kunye nee turbines ezahlukeneyo zerhasi. Ukuba amandla ahlala e-150MPA-100H asetyenziswa njengomgangatho, elona qondo lobushushu liphezulu elinokumelana ne-nickel alloys ngu>1100 ° C, ngelixa i-nickel alloys malunga ne-950 ° C, kunye ne-iron-based alloys yi-<850 ° C, oko kukuthi. , iialloyi ezisekwe kwi-nickel ziphezulu ngokuhambelanayo nge-150°C ukuya malunga ne-250°C. Ngoko abantu bayibiza i-nickel alloy intliziyo ye-injini. Okwangoku, kwiinjini eziphambili, i-nickel alloys yenza isiqingatha sobunzima bubonke. Ayizizo iiblade ze turbine kuphela kunye namagumbi okutsha, kodwa neediski ze turbine kunye nezigaba zokugqibela zecompressor blades sele ziqalisile ukusebenzisa ialloyi zenickel. Xa kuthelekiswa ne-alloys yensimbi, iingenelo ze-nickel alloys zezi: ukushisa okuphezulu kokusebenza, isakhiwo esizinzile, izigaba ezinobungozi obuncinci kunye nokuchasana okuphezulu kwi-oxidation kunye ne-corrosion. Xa kuthelekiswa ne-cobalt alloys, i-nickel alloys inokusebenza phantsi kobushushu obuphezulu kunye noxinzelelo, ngakumbi kwimeko yokunyakaza kwee-blades.

I-5J1480 i-bimetal ye-thermal 5J1480 echanekileyo i-alloy 5J1480 superalloy Iron-nickel alloy Iinzuzo ezikhankanywe ngasentla ze-nickel alloy zihambelana nezinye iimpawu zayo ezintle. I-Nickel sisakhiwo se-cubic esigxile ebusweni kunye ne- kakhulu

Izinzile, akukho tshintsho lwe-allotropic ukusuka kwiqondo lokushisa ukuya kwiqondo lokushisa eliphezulu; oku kubaluleke kakhulu ekukhethweni njengento ye-matrix. Kuyaziwa ukuba isakhiwo se-austenitic sinoluhlu lweenzuzo ngaphezu kwesakhiwo se-ferrite.

I-Nickel inozinzo oluphezulu lweekhemikhali, ayifaki i-oxidize ngaphantsi kwe-500 degrees, kwaye ayichatshazelwa ngumoya ofudumeleyo, amanzi kunye nezinye izisombululo zetyuwa emanzi kubushushu besikolo. I-nickel iyancibilika ngokukhawuleza kwi-asidi ye-sulfuric kunye ne-hydrochloric acid, kodwa ngokukhawuleza kwi-nitric acid.

I-Nickel inamandla amakhulu okusebenzisa i-alloying, kwaye ukongeza ngaphezu kweentlobo ezilishumi ze-alloying element akubonakali izigaba ezinobungozi, ezibonelela ngamathuba okuphucula iipropati ezahlukeneyo ze-nickel.

Nangona iimpawu zemishini ye-nickel ecocekileyo ayinamandla, iplastiki yayo ihle kakhulu, ngakumbi kwiqondo lokushisa eliphantsi, iplastiki ayitshintshi kakhulu.

Iimpawu kunye nokusetyenziswa: uvakalelo lobushushu obuphakathi kunye nokumelana okuphezulu. Inzwa ye-Thermal kumlinganiselo wobushushu obuphakathi kunye nezixhobo zokulawula ngokuzenzekelayo
