Icyuma gishingiye ku byuma / Nickel ishingiye ku mavuta / Nickel ishingiye ku mavuta / isahani irwanya ruswa ya superalloy

Nickel ishingiye kuri superalloys nicyiciro cyimvura ikomeza ibishishwa bikora neza mubushyuhe bwo hejuru. Ibintu byiza cyane byo hejuru yubushyuhe bwa nikel-ishingiye kuri superalloys byatumye habaho ishyirwa mubikorwa ryiki cyiciro cya alloys mubikorwa byinshi byo mu kirere.

Icyuma gishingiye ku cyuma ni ubwoko bwa superalloy. Irangwa no kongeramo ibindi bintu hashingiwe ku cyuma cyo kuvanga. Bihuye na superalloys ishingiye kuri fer ni superalloys ishingiye kuri nikel na superalloys ishingiye kuri cobalt.

Cobalt ishingiye kuri superalloys ni ibikoresho bikoreshwa mubushyuhe bwo hejuru hamwe nibidukikije bikabije hamwe nubushyuhe buhebuje bwo hejuru, kurwanya ruswa no kwihanganira kwambara. Cobalt ishingiye kuri superalloys igizwe ahanini nibintu nka cobalt, chromium, tungsten, nikel na aluminium.

Kurwanya ruswa irwanya ruswa itanga ubwiyongere bwimbaraga za mashini, kurwanya ihindagurika ryumuriro, hamwe no kurwanya ruswa ugereranije nudukoko twa gakondo, bisaba kubungabungwa bike no guhangana n’ibidukikije bikaze. Harimo gushyirwaho ingufu zo gukora ibibyimba bishya birwanya ruswa nka aluminiyumu ishingiye kuri super alloys, no gushyiraho uburyo bushya bwo gukora nka radiolisi ikoresha synthesis ya nano-selile kugirango polycristaline ikorwe.

Kurwanya ubushyuhe bwinshi no kurwanya ruswa ya superalloy ahanini biterwa nimiterere yimiti n'imiterere. Dufashe urugero rwa Inconel718 ya nikel ishingiye kuri superalloy nk'urugero, ibinyobwa bigizwe na phase matrix icyiciro, δ icyiciro, karbide, hamwe nicyiciro cya γ 'na γ. gushimangira ibintu bigira uruhare muburyo bwiza bwubukanishi.

Bitewe nibikorwa bigoye kandi bikaze byakazi bya superalloys, ubusugire bwubuso bwimashini bugira uruhare runini mubikorwa byabwo. Nyamara, superalloy isanzwe igoye gutunganya ibikoresho, ubukana bwayo mikorobe ikomera ni ndende, urwego rwo gukomera kumurimo rurakomeye, kandi rufite impagarara zogosha cyane hamwe nubushyuhe buke bwumuriro, kugabanya ingufu no kugabanya ubushyuhe mukarere kaciwe, akenshi bigaragara mugutunganya ubuziranenge bwubutaka, kwangiza ibikoresho birakomeye cyane nibindi bibazo. Mubihe rusange byo guca ibintu, hejuru yubuso bwa superalloy bizatanga ibibazo binini cyane nkurwego rukomye, guhangayika gusigaye, umweru wera, igipande cyumukara hamwe nubutaka bwimbuto.

Superalloys ni amavuta arwanya nikel, fer-nikel, na cobalt bishobora gukoreshwa mubushyuhe bwinshi, akenshi> 70% byubushyuhe bwabyo. Birashobora gukoreshwa mubushyuhe burenga 1050 ° C hamwe ningendo zigera kuri 1200 ° C. Ubu bushyuhe burwanya ubushyuhe butuma iba umukandida usimbuye wa Tungsten Carbide muri Pick Up.

Ubwoko bwa Superalloy bukoreshwa cyane ni ibikoresho bishingiye kuri nikel birimo ibintu byinshi bya chromium, fer, titanium, cobalt nibindi bintu bivanga. Kimwe nandi matsinda yibikoresho byibyuma, imiterere ya superalloys irashobora guhindurwa hamwe nuburyo butandukanye bwo kuvura ubushyuhe hamwe na / cyangwa guhuza no kuzimya. Ugereranije nandi matsinda yibintu, Superalloys ifite ubushyuhe bwo hejuru bwa serivise nuburemere bukomeye. Imbaraga za Superalloys ituma inzira nziza ya Carbide murwego rwo hejuru rwingufu zikoreshwa (> 1kg).
