Duplex ibyuma bitagira umuyonga 2205 uburyo bwo gusudira no kwirinda

1. Igisekuru cya kabiri cyicyuma cya duplex kitagira umuyonga gifite ibiranga karubone ntoya cyane, azote nkeya, ibisanzwe bisanzwe Cr5% Ni0.17% n na 2205 birenze urugero bya azote ugereranije nigisekuru cya mbere cyibyuma bya duplex ibyuma bitagira umuyonga, biteza imbere kurwanya ruswa no guhuza itangazamakuru rya 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 pariki, austenite na ferrite bingana na 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 kimwe cyumuvuduko wumuvuduko urashobora kubika ibikoresho, imbaraga zumusaruro hamwe ningutu yo kwangirika kwangirika kwicyuma cya duplex ibyuma bitagira ibyuma byikubye hafi inshuro 1 icyuma cya austenitike kitagira ibyuma, coefficente yo kwagura umurongo ntikiri munsi yicyuma cya austenitike kitagira ibyuma bya sisitemu ya austenitike, kandi ibyuma bya karubone biri hafi yacyo. Gukonjesha gukonje ntabwo ari byiza nkicyuma cya austenitis.

4. Bitewe 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 byo gukonjesha bishyushye 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 kubyara umusaruro, kandi gukura byihuse kwingaruka zintete ntibibaho mubushyuhe bwinshi.

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 nubushuhe bwibasiwe nubushyuhe bwicyuma gisudira byagiye bihinduka. Ku bushyuhe bwinshi, microstructure ya duplex ibyuma bidafite ibyuma bigwa na ferrite na austenite mugihe cyo gukonja. Ingano yimvura ya austenite iterwa nibintu byinshi.
