Kuzimya iki:
Kuzimya, nanone bita Gukomera ni ugushyushya no gukonjesha ibyuma nyuma yumuvuduko kuburyo habaho kwiyongera gukomeye kwubukomere, haba hejuru cyangwa hose.Ku bijyanye no gukomera kwa vacuum, iki gikorwa gikorerwa mu itanura rya vacuum aho ubushyuhe bugera kuri 1,300 ° C bushobora kugerwaho.Uburyo bwo kuzimya buzatandukana kubijyanye nibikoresho bivurwa ariko kuzimya gaze ukoresheje azote nibisanzwe.
Mubihe byinshi gukomera bibaho bifatanije nubushyuhe bwakurikiyeho, ubushyuhe.Ukurikije ibikoresho, gukomera bizamura ubukana no kwambara birwanya cyangwa bigenga igipimo cyo gukomera no gukomera.
Ubushyuhe ni iki:
Ubushyuhe ni uburyo bwo gutunganya ubushyuhe bukoreshwa mubyuma nk'ibyuma cyangwa ibyuma bishingiye ku byuma kugira ngo bigere ku gukomera gukabije kugabanya ubukana, ubusanzwe buherekezwa no kwiyongera kw'imyanda.Ubushuhe bukorwa mubisanzwe nyuma yo gukomera mugushyushya icyuma ubushyuhe buri munsi yikintu gikomeye mugihe runaka, hanyuma ukemerera gukonja.Ibyuma bitageragejwe birakomeye cyane ariko akenshi biravunika cyane kubikorwa byinshi.Ibyuma bya karubone hamwe nicyuma gikora ibikoresho bikonje bikunze gushyukwa mubushyuhe bwo hasi, mugihe ibyuma byihuta cyane hamwe nibikoresho byakazi bishyushye bikoreshwa mubushyuhe bwinshi
Annealing Niki:
Annealing mu cyuho
Annealing kuvura ni inzira aho ibice bishyuha hanyuma bigakonja buhoro buhoro kugirango ubone imiterere yoroshye yikigice no kunoza imiterere yibintu kugirango intambwe ikurikiraho.
Iyo annealing munsi ya vacuum inyungu zikurikira zitangwa ugereranije no kuvura munsi yikirere:
Kwirinda okiside ya intergranular (IGO) hamwe na okiside yo hejuru wirinda de-carburize ahantu h'ubutare, hejuru yubusa isukuye hejuru yibice nyuma yo kuvura ubushyuhe, nta gukaraba ibice bikenewe.
Inzira zizwi cyane ni:
Guhangayikishwa no guhagarika umutima bikorwa ku bushyuhe bugera kuri 650 ° C hagamijwe kugabanya imihangayiko yimbere yibigize.Izi mpagarara zisigaye ziterwa nintambwe zabanjirije inzira nka casting hamwe nicyatsi kibisi.
Guhangayikishwa cyane birashobora gutuma umuntu agoreka bidakenewe mugihe cyo gutunganya ubushyuhe cyane cyane kubice bikikijwe.Birasabwa rero gukuraho izo mihangayiko mbere yubuvuzi bwa "nyabwo" bwo kuvura ubushyuhe ukoresheje imiti igabanya ubukana.
Recrystallisation annealing irakenewe nyuma yimikorere ikonje kugirango igarure microstructure yambere.
Igisubizo niki gusaza
Gusaza ninzira ikoreshwa mukongera imbaraga mukubyara imvura yibintu bivanga mubyuma.Umuti wo gukemura ni ugushyushya amavuta kubushyuhe bukwiye, ukayifata kuri ubwo bushyuhe igihe kirekire bihagije kugirango utume umwe cyangwa benshi binjira mubisubizo bihamye hanyuma bikonjesha vuba bihagije kugirango ibyo bisubizo bikemuke.Ubushyuhe bwimvura ikurikiraho butuma irekurwa ryibintu bisanzwe mubisanzwe (kubushyuhe bwicyumba) cyangwa muburyo bwubukorikori (kubushyuhe bwinshi).
Amatanura yatanzwe kugirango avurwe ubushyuhe
