Inkqubo ye-Nickel Alloys Heat Treatment ngokubanzi ibandakanya iinkqubo ezintathu zeukufudumeza, ukugcinwa kobushushu,kwayeUkupholisa, kwaye ngamanye amaxesha kukho iinkqubo ezimbini kuphela zokufudumeza kunye nokupholisa.Ezi nkqubo zixhunyiwe kwaye aziphazamiseki.
Ukufudumeza
Ukufudumezayenye yeenkqubo ezibalulekileyo zonyango lobushushu.Zininzi iindlela zokufudumeza zonyango lwetsimbi.Ukusetyenziswa kwangoko kwamalahle kunye namalahle njengemithombo yobushushu, emva koko kusetyenziswa izibaso ezingamanzi kunye nerhasi.Ukusetyenziswa kombane kwenza ukufudumeza kube lula ukulawula, kwaye akukho ngcoliseko yendalo.Le mithombo yobushushu ingasetyenziselwa ukufudumeza ngokuthe ngqo, okanye ukufudumeza ngokungathanga ngqo ngetyuwa etyhidiweyo okanye isinyithi, okanye amasuntswana adadayo.
Xa isinyithi sifudunyezwa, i-workpiece ibonakaliswe emoyeni, kwaye i-oxidation kunye ne-decarburization ihlala isenzeka (oko kukuthi, umxholo wekhabhoni womphezulu weendawo zetsimbi uyancitshiswa), onempembelelo embi kakhulu kwiipropati zomphezulu womhlaba. iinxalenye emva kokunyanga ubushushu.Ke ngoko, iintsimbi kufuneka zifudunyezwe kwindawo elawulwayo okanye kwindawo ekhuselayo, ityuwa enyibilikisiweyo, kunye ne-vacuum, kunye neendlela zokugquma okanye ukupakisha nazo zinokusetyenziselwa ukukhusela kunye nokufudumeza.
Ubushushu bokufudumala ngenye yeeparameters zenkqubo ebalulekileyo yenkqubo yokunyanga ukushisa.Ukukhethwa kunye nokulawulwa kobushushu bokufudumala ngumba oyintloko wokuqinisekisa umgangatho wonyango lokushisa.Ubushushu bokufudumala buhluka kunye nezinto zetsimbi ezicutshungulwayo kunye nenjongo yonyango lokushisa, kodwa ngokuqhelekileyo kushushu ngaphezu kweqondo elithile lokutshintsha kweempawu ukufumana isakhiwo esiphezulu sokushisa.Ukongeza, utshintsho lufuna ixesha elithile.Ngoko ke, xa ubuso bomsebenzi wensimbi bufikelela kwiqondo lokushisa elifunekayo, kufuneka ligcinwe kule qondo lokushisa ixesha elithile ukwenza ukushisa kwangaphakathi nangaphandle kuhambelana kwaye kuzaliseke ukuguqulwa kwe-microstructure.Eli xesha libizwa ngokuba lixesha lokubamba.Xa kusetyenziswa ubushushu obuphezulu be-energy kunye nonyango lobushushu bomhlaba, isantya sokufudumeza sikhawuleza kakhulu, kwaye akukho xesha libambekayo, ngelixa ixesha lokubamba lonyango lobushushu bekhemikhali lihlala lide.
Phola
Ukupholisaikwalinyathelo eliyimfuneko kwinkqubo yonyango lobushushu.Indlela yokupholisa iyahluka ukusuka kwinkqubo ukuya kwinkqubo, kwaye into ephambili kukulawula izinga lokupholisa.Ngokubanzi, i-annealing inelona zinga lokupholisa elicothayo, isantya sokupholisa esiqhelekileyo siyakhawuleza, kwaye isantya sokupholisa sikhawuleza.Nangona kunjalo, kukho iimfuno ezahlukeneyo ngenxa yamanqanaba ahlukeneyo ensimbi.Umzekelo, intsimbi eqinileyo engenanto ingacinywa ngesantya esifanayo sokupholisa njengesiqhelo.
