Duplex ibyuma bitagira umuyonga umuyoboro 2205 wo gusudira no kwirinda

. kurwanya imbaraga zo kwangirika no kurwanya imiti ya acide hamwe na chloride ion nyinshi.Azote nikintu gikomeye gikomeye cya austenite.Kwiyongera kwa azote muri duplex ibyuma bitagira umuyonga ntabwo byongera gusa plastike nubukomezi bwibyuma nta byangiritse bigaragara, ahubwo binatezimbere imbaraga zicyuma, kandi bikabuza kugwa no gutinda kwa karbide.

2. Imikorere yubuyobozi: Muri parike, austenite na ferrite hafi kimwe cya kabiri cyigisubizo gikomeye, gifite ibiranga imiterere ya biphase.Igumana ibiranga umubare muto wa ferritic idafite ibyuma bitwara ibyuma, kurwanya ibinogo, kumeneka hamwe na chloride yibora, hamwe nubukomezi bwiza, ubushyuhe buke buke, kurwanya ruswa hagati yimiterere yimiterere nubukanishi hamwe no gusudira neza.

3. Mugihe cyurwego rumwe rwumuvuduko urashobora kubika ibikoresho, imbaraga zumusaruro hamwe ningutu zo kwangirika kwangirika kwicyuma cya duplex ibyuma bitagira ibyuma byikubye inshuro 1 inshuro 1 icyuma cya austenitike kitagira ibyuma, coefficente yo kwagura umurongo ntikiri munsi yicyuma cya austenitike kitagira umuyonga wa austenitis sisitemu yicyuma, nicyuma gito cya karubone kiri hafi yacyo.Gukonjesha gukonje ntabwo ari byiza nkicyuma cya austenitis.

4Bitewe nubushake buke bwa ferrite yicyiciro kimwe hamwe na azote nyinshi muri zone yibasiwe nubushyuhe, ingufu zinsinga zo gusudira zirashobora kugenzurwa muriki gihe mugihe ibikoresho byo gusudira byatoranijwe neza, kandi imikorere yuzuye nibyiza.

5. Igicucu gishyushye: Ibyiyumvo byumuriro ushushe biri hasi cyane ugereranije nicyuma cya austenitis.Ibi ni ukubera ko nikel itari hejuru, umwanda woroshye gukora eutectic yo gushonga gake ni muke, firime yamazi ifite aho ishonga ntago byoroshye kuyibyaza umusaruro, kandi ubwiyongere bwihuse bwikibazo cyibinyampeke ntibubaho hejuru ubushyuhe.

6. Ubuke bwa zone yibasiwe nubushyuhe: Ikibazo nyamukuru cyo gusudira ibyuma bya duplex ibyuma bitagira umuyonga ni zone yibasiwe nubushyuhe.Bitewe ningaruka zo gukonjesha byihuse bya zone yibasiwe nubushyuhe muburyo butaringaniye bwubushyuhe bwo gusudira, ferrite ikonje cyane ihora igumishijwe, ikunda kongera ubukana bwa ruswa hamwe na hydrogène iterwa no guturika.

7. Metallurgie yo gusudira: Mugihe cyo gusudira ibyuma bya duplex bitagira umuyonga, munsi yumukino wo gusiganwa ku magare, microstructure hamwe na zone yibasiwe nubushyuhe bwicyuma cyasuditswe byagiye bihinduka.Ku bushyuhe bwinshi, microstructure ya duplex idafite ibyuma itwarwa na ferrite na austenite mugihe cyo gukonja.Ingano yimvura ya austenite iterwa nibintu byinshi.
