Itandukaniro ryibigize
Amavuta ashingiye kuri Cobalt akoresha cobalt (Co), chromium (Cr), molybdenum (Mo), nibindi nkibintu nyamukuru, muri byo cobalt ikagira igice kinini, kandi umubare munini wicyuma (Fe), karubone (C) nibindi byongeweho; nikel-ishingiye kuri nikel ikoresha nikel (Ni) nkibintu nyamukuru, ikanongeramo chromium (Cr), molybdenum (Mo), umuringa (Cu), titanium (Ti), niobium (Nb) nibindi bintu.
Itandukaniro ryimikorere
Amavuta ashingiye kuri Cobalt afite akazi keza ko gukomera no koroshya ibintu, kandi byoroshye gutunganywa muburyo butandukanye. Birakwiriye gutunganya ibice ukoresheje cobalt ishingiye ku mavuta. Amavuta ya Nickel ashingiye kubikorwa kandi byoroshye guhimba, gusohora no gukora rotor, kandi birakwiriye gutunganya ibice. Gutezimbere no kunoza imashini yihuta yihuta ukoresheje nikel ishingiye kuri nikel.
1.Ubuvuzi bushyushye: Byombi ubushyuhe bwo hejuru busaba kuvura ubushyuhe. Bombi bafata uburyo bwo kuvura ubushyuhe bwo kuvura igisubizo gikomeye + kuvura gusaza. Ingorabahizi yuburyo bwo gutunganya ubushyuhe ni bumwe.
2.Weldability: Byombi ubushyuhe bwo hejuru burimo gusudira neza. Mugihe cyo gusudira kashe ya kashe, ubushyuhe biroroshye kwegeranya no gutera deformasiyo. Birasabwa gukoresha ibikoresho bishingiye kuri cobalt, bifite ubushyuhe bwinshi, ubushyuhe bukomeye bwumuriro, coefficient nto yo kwaguka, hamwe no guhindura ibintu bito. , gusudira fusion imbaraga nibyiza.
3.Gutunganya gutunganya: Gutunganya ibintu neza birashobora gukorwa.
Byombi ubushyuhe bwo hejuru buvanze bifite imikorere myiza.
Itandukaniro ryimikorere
1. Kurwanya ruswa:
Amavuta ya Cobalt afite imiti irwanya kwambara, kurwanya ruswa hamwe nubushyuhe bwo hejuru, kandi irashobora gukomeza imikorere ihamye mubidukikije bikabije nka acide ikomeye, alkali ikomeye, ubushyuhe bwinshi n’umuvuduko mwinshi, kandi ikwiranye ninganda zikora zikeneye kwihanganira imitwaro myinshi nibidukikije bikabije;
Amavuta ya Nickel afite imbaraga zo kurwanya ruswa kandi arashobora gukomeza gutuza no kuba inyangamugayo mubitangazamakuru bitandukanye byangirika. Bafite kandi ubushyuhe buhebuje bwo hejuru kandi burashobora gukomeza imbaraga nubukomere mubushyuhe bwo hejuru. Ariko ntibikwiye kubitangazamakuru byangiza cyane.
2.Ubushyuhe bwumuriro: Amavuta ashingiye kuri Cobalt afite imiterere yubushyuhe bwo hejuru kuruta amavuta ya nikel kandi arashobora gukoreshwa mubushyuhe bwo hejuru hejuru ya 1200 ° C mugihe kirekire, mugihe amavuta ashingiye kuri nikel ashobora gukoreshwa gusa kuri 1000 ° C. Amavuta ashingiye kuri Cobalt afite aho ashonga cyane hamwe nubushyuhe bwumuriro, kwaguka kwinshi nyuma yo gushyuha, kandi bifite ibyiza mumashanyarazi; nikel ishingiye kuri nikel ifite imbaraga zo kurwanya okiside no kwangirika, ariko mubihe byubushyuhe bwo hejuru, cobalt Amavuta yibanze afite imbaraga zo kurwanya ubushyuhe bwo hejuru cyane hamwe nubushyuhe bwo hejuru.
3.Imbaraga za mashini: Amavuta ya Cobalt afite imbaraga zubushyuhe bwo hejuru kandi arwanya umunaniro mwinshi wumuriro, mugihe amavuta ya nikel ashingiye ku guhindagurika no gutunganywa neza, ariko imbaraga zubushyuhe bwo hejuru hamwe nubushyuhe bwumuriro buruta kure cyane ya alubumu ishingiye kuri cobalt. . Ku bushyuhe bwicyumba, imbaraga za cobalt zishingiye ku mavuta ziri munsi gato, ariko kurambura ni byinshi; nikel ishingiye kuri nikel ifite imbaraga zisumba izindi, ariko ziroroshye, kandi zigomba gukoreshwa mubwitonzi ahantu hamwe ningaruka. Ku bushyuhe bwinshi, iyo ubushyuhe buri kuri 650 ° C, ibinyomoro bishingiye kuri nikel bifite imbaraga nyinshi, ariko kandi biravunika cyane, kandi bikunze kuvunika iyo bikoreshejwe mubihe byingaruka. Iyo ubushyuhe buzamutse bugera kuri 900 ° C, superalloy ishingiye kuri nikel ntigishobora gukoreshwa, mugihe superalloy ishingiye kuri diyama iracyafite imbaraga runaka.
4. Gukomera kwa mashini: Ibyo bita gukomera nubushobozi bwibikoresho byo kurwanya ihinduka. Ubukomezi bwa nikel bushingiye kuri nikel buri munsi yubwa cobalt bushingiye ku mavuta yose.
Uumunyabwenge
Amavuta ashingiye kuri Cobalt akoreshwa kenshi mugukora ibice bitandukanye nibice bitandukanye birwanya kwambara, birwanya ruswa, ubushyuhe bwinshi kandi birwanya ingaruka zakazi; nikel ishingiye kuri nikel ikoreshwa cyane mu ndege, mu kirere, ingufu, mu nyanja, kurengera ibidukikije no mu zindi nzego, cyane cyane Gukora ibice by'ingenzi nka blade ya turbine n'ibyumba byo gutwika muri moteri ya aero.
