Unyango lobushushuyinkqubo apho izinto zetsimbi zifudunyezwa, zigcinwe zifudumele kwaye zipholile kwindawo ethile, kwaye iimpawu zabo zilawulwa ngokuguqula isakhiwo se-metallographic kumphezulu okanye ngaphakathi kwezinto.
Iimpawu zenkqubo
Ukunyangwa kobushushu besinyithi yenye yeenkqubo ezibalulekileyo ekuveliseni oomatshini.Xa kuthelekiswa nobunye ubuchwephesha bokucwangcisa, unyango lobushushu aluyitshintshi imilo kunye nokwakheka kweekhemikhali ngokubanzi kwendawo yokusebenza, kodwa lutshintsha ulwakhiwo lwemicro ngaphakathi kwendawo yokusebenza okanye lutshintshe ukwakheka kweekhemikhali zomphezulu womsebenzi., ukunika okanye ukuphucula ukusebenza kwe-workpiece.Ibonakaliswa ngokuphucula umgangatho wangaphakathi we-workpiece, ngokuqhelekileyo ingabonakali ngeso lenyama.
Ukuze wenze i-workpiece yensimbi ibe nezixhobo ezifunekayo zomatshini, iipropati ezibonakalayo kunye neekhemikhali, ngaphezu kokukhethwa okufanelekileyo kwezinto kunye neenkqubo ezahlukeneyo zokubumba, inkqubo yonyango lokushisa isoloko iyimfuneko.Intsimbi yeyona nto isetyenziswa kakhulu kwishishini loomatshini.I-microstructure yensimbi iyinkimbinkimbi kwaye inokulawulwa ngonyango lokushisa.Ngoko ke, unyango olushushu lwentsimbi ngowona mxholo uphambili wonyango lwentsimbi.Ukongeza, i-aluminiyam, ubhedu, i-magnesium, i-titanium, njl. kunye ne-alloys zabo nazo zinokuphathwa ubushushu ukuze zitshintshe iipropathi zabo zomatshini, zomzimba kunye neekhemikhali zokufumana ukusebenza okwahlukileyo.
Inkqubo yonyango lokushisa
Inkqubo yokunyanga ukushisa ngokubanzi ibandakanya iinkqubo ezintathu zokufudumeza, ukugcinwa kobushushu kunye nokupholisa, kwaye ngamanye amaxesha kukho iinkqubo ezimbini kuphela zokufudumeza kunye nokupholisa.
Ukufudumeza enye 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 kungcoliseko kwendalo.Le mithombo yobushushu ingasetyenziselwa ukufudumeza ngokuthe ngqo okanye ukufudumeza ngokungathanga ngqo ngeetyuwa ezityhidiweyo okanye isinyithi, kunye namasuntswana adadayo.
Xa isinyithi sishushu, i-workpiece ibonakaliswe emoyeni, kwaye i-oxidation kunye ne-decarburization ihlala isenzeka (oko kukuthi, umxholo wekhabhoni phezu kwendawo yentsimbi iyancitshiswa), enefuthe elibi kakhulu kwiipropati zomphezulu womhlaba. iinxalenye emva kokunyanga ubushushu.Ngoko ke, isinyithi kufuneka ngokuqhelekileyo sifudunyezwe kwindawo elawulwayo okanye indawo ekhuselayo, kwityuwa etyhidiweyo kunye ne-vacuum, kwaye inokukhuselwa ngeendlela zokugqoka okanye zokupakisha.
Ubushushu bokufudumala ngenye yeeparameters zenkqubo ebalulekileyo yenkqubo yokunyanga ukushisa.Ukukhethwa kunye nokulawulwa kobushushu bokufudumala yingxaki ephambili yokuqinisekisa umgangatho wonyango lokushisa.Ubushushu bokufudumala buhluka kunye nezinto zetsimbi eziza kucutshungulwa kunye nenjongo yonyango lokushisa, kodwa ngokuqhelekileyo kushushu ngaphezu kweqondo lokushisa lokutshintsha kwesigaba ukufumana isakhiwo esiphezulu sokushisa.Ukongeza, ukuguqulwa kuthatha ixesha elithile, ngoko xa umphezulu we-workpiece yentsimbi ufikelela kwiqondo lokushisa elifunekayo lokufudumeza, kufuneka ligcinwe kulo bushushu kangangexesha elithile ukwenza ubushushu bangaphakathi nangaphandle buhambelane kunye ne-microstructure. utshintsho ngokupheleleyo.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.
Ukupholisa kwakhona linyathelo eliyimfuneko kwinkqubo yonyango lobushushu.Indlela yokupholisa iyahluka kunye neenkqubo ezahlukeneyo, ngokukodwa ukulawula izinga lokupholisa.Ngokuqhelekileyo, izinga lokupholisa lokuthotywa kwesisu lelona licothayo, izinga lokupholisa lesiqhelo liyakhawuleza, kwaye izinga lokupholisa lokucinywa likhawuleza.Nangona kunjalo, kukho kwakhona iimfuno ezahlukeneyo ngenxa yeentlobo ezahlukeneyo zetsimbi.Umzekelo, intsimbi enomngxuma eqinileyo inokuqiniswa ngesantya sokupholisa esifanayo njengesiqhelo.
