Kuzimya no gutondeka inzira ya 316L idafite ibyuma

Kuzimya no gucana ni uburyo bwo gutunganya ubushyuhe bukoreshwa mugutezimbere ibikoresho bya tekinike, harimo ibyuma bitagira umwanda nka 316L. Izi nzira zikoreshwa kenshi mukuzamura ubukana, imbaraga, no gukomera mugihe gikomeza kurwanya ruswa. Dore uburyo inzira yo kuzimya no gutuza ishobora gukoreshwa kumurongo wa 316L idafite ingese:

1. Annealing (Bihitamo): Mbere yo kuzimya no gutwarwa, urashobora guhitamo guhuza umugozi wibyuma 316L utagira umuyonga kugirango ugabanye imihangayiko yimbere kandi urebe ibintu bimwe. Annealing ikubiyemo gushyushya ibyuma ubushyuhe bwihariye (mubisanzwe hafi 1900 ° F cyangwa 1040 ° C) hanyuma ukonjesha buhoro buhoro muburyo bugenzurwa.
2. Kuzimya: Shyushya umurongo wa 316L udafite ingese kugeza ku bushyuhe bwawo bwa austenitis, ubusanzwe hafi 1850-2050 ° F (1010-1120 ° C) bitewe nibigize.
   Fata ibyuma kuri ubu bushyuhe mugihe gihagije kugirango ushushe kimwe.
   Zimya ibyuma byihuse ubishiramo uburyo bwo kuzimya, ubusanzwe amavuta, amazi, cyangwa igisubizo cya polymer. Guhitamo kuzimya ibikoresho biterwa nibintu byifuzwa hamwe nubunini bwumurongo.
   Kuzimya byihuta gukonjesha ibyuma, bigatuma ihinduka kuva austenite ikajya mugice gikomeye, cyoroshye cyane, martensite.
3. Ubushyuhe: Nyuma yo kuzimya, ibyuma bizaba bikomeye cyane ariko byoroshye. Kunoza ubukana no kugabanya ubukana, ibyuma birahinduka.
   Ubushyuhe bukabije ni ingenzi kandi mubisanzwe buri hagati ya 300-1100 ° F (150-590 ° C), bitewe nibintu byifuzwa. Ubushyuhe nyabwo buterwa na progaramu yihariye.
   Fata ibyuma ku bushyuhe bwubushyuhe mugihe runaka, gishobora gutandukana ukurikije ibintu wifuza.
   Uburyo bwo kugabanura bugabanya ubukana bwicyuma mugihe butezimbere ubukana bwacyo. Ubushyuhe bwo hejuru, ubushyuhe bworoshye kandi buhindagurika ibyuma bizaba.
4. Gukonjesha: Nyuma yo gukonjesha, emera 316L ibyuma bitagira umuyonga gukonjesha bisanzwe mu kirere cyangwa ku kigero cyagenwe n'ubushyuhe bw'icyumba.
5. Kwipimisha no Kugenzura Ubuziranenge: Ni ngombwa gukora ibizamini bya mehaniki na metallurgjiya kumurongo wazimye kandi ushushe kugirango urebe ko wujuje ibyifuzo n'imiterere. Ibi bizamini birashobora kuba bikubiyemo kwipimisha ubukana, kugerageza ibintu, kugerageza ingaruka, no gusesengura microstructure. Ibipimo byihariye byo kuzimya nubushyuhe, nkubushyuhe nigihe cyigihe, bigomba kugenwa hashingiwe kumiterere isabwa kubisabwa kandi birashobora gusaba kugerageza no kugerageza. Kugenzura neza ubushyuhe, gufata, kuzimya, hamwe nubushuhe nibyingenzi kugirango ugere ku ntera yifuzwa yo gukomera, imbaraga, no gukomera mugihe ukomeje kurwanya ruswa muri 316L ibyuma bitagira umwanda. Byongeye kandi, ingamba z'umutekano zigomba gufatwa mugihe ukorana nubushyuhe bwo hejuru hamwe no kuzimya.
