Electron beam gushonga 3D icapa titanium aluminium igizwe nibice byubatswe
TiAl ishingiye kuri alloy ifite ibiranga ubucucike buke, imbaraga zidasanzwe, modulus nyinshi, kurwanya ubushyuhe bwo hejuru bwa okiside, nibindi, bikaba byoroshye nka 50% kuruta nikel ishingiye kuri superalloy.
Ibyuma bya elegitoronike bishonga ibyumaIcapiro rya 3D tekinoroji yo gutegura ibikoresho bya TiAl bishingiye ku buhanga nkuburyo bushya kandi bugezweho bwo gukora, bifatwa nkuburyo bwiza bwo gukora ibikoresho bya TiAl bishingiye ku mavuta, hamwe na micro-zone idasanzwe yo gushonga, kuvura ubushyuhe bwizuba, gukomera byihuse nibindi byiza byikoranabuhanga . Ibibazo byuburyo bubi nuburyo bukomeye bwo gukomera muri casting, ingot metallurgie na powder metallurgie biratsindwa. Bitewe nibiranga ubwayo, bizana ibibazo bikomeye bya tekiniki kubikorwa bya elegitoroniki.
Muri Werurwe 2021, ingorane za tekiniki nko gusenyuka kw'ifu (guhuha ifu), guhuza imikoranire idahagije, guhindagurika kwaaluminium, ubucucike buke, guhinduranya kutaringaniye hamwe nuburyo burebure bwimiterere yibice byakemuwe mugikorwa cya beam electron ikora TiAl alloy.
Gukwirakwiza no kuzamura ibipimo ngenderwaho kugirango hategurwe ibice binini binini byubatswe hifashishijwe ibikoresho bya elegitoroniki ya elegitoronike ishonga 3d ikoranabuhanga rya printer, kugenzura intego ihindagurika rya microstructure ihindagurika ryibikoresho ahantu hirengeye, no guhindura ibipimo byimikorere nuburyo bwo gucapa, Ø110mm × 66mm yuzuye cyane kandi Trek-48Al-2Cr-2Nb supercharger turbine yarakozwe neza. Iterambere rishya ryakozwe muri titanium na aluminium igizwe nibice byubatswe. Mugihe kimwe, mugutezimbere inzira yo gusikana hamwe no kwibanda kumurongo, inzira yo gushiraho ibice byinzibacyuho bigoramye byatsinzwe.
Ifu ya elegitoroniki yamashanyarazi yahise iturika
Binyuze mu gutezimbere no kuzamura ibikorwa byo gushyushya, ubunini bwikigereranyo kinini hamwe nigikorwa kimwe murwego rutandukanye cyacapwe neza
Electron beam 3D icapa uburebure bwa 90mm Ti-48Al-2Cr-2Nb inkoni yikizamini
Nyuma yo gutinda kwinyandiko zitinze, microstructure ya transvers na longitudinal ya Ti-48Al-2Cr-2Nb yari imwe, kandi ubucucike bushobora kugera kuri 99,6%. Imbonerahamwe ikurikira irerekana impuzandengo yimiterere yimikorere ya transvers na longitudinal test bar.
| Ubushyuhe | Tanga imbaraga | Imbaraga | Igipimo cyo kuramba |
| 650 ° C. | ≥410 | 00500 | ≥1.2 |
| Ubushyuhe bw'icyumba | 30430 | ≥510 | ≥1.8 |
Ibikoresho bya tekinike ya Ti-48Al-2Cr-2Nb ifu yacapishijwe na tekinoroji ya electron
Ibikoresho bya elegitoronike bikora Ø110mm × 66mm Ti-48Al-2Cr-2Nb alloy turbocharger
Electron beam 3D icapa uburebure bwa 90mm Ti-48Al-2Cr-2Nb inkoni yikizamini
Biravugwa ko GE Aviation yatangaje ku mugaragaro ko moteri ya GE9XFAA yemejwe n’ubuyobozi bukuru bw’indege (FAA), kandi moteri ifite ibice birenga 300 byongera inganda, muri byo titanium aluminium y’umuvuduko ukabije wa turbine ikozwe na beam guhitamo gushonga tekinoroji ni imwe murimwe.
