Aero-moteri nimwe mubintu byingenzi bigize indege.Ibi ni ukubera ko bifite tekinoroji yo hejuru isabwa kandi biragoye kuyikora.Nkigikoresho cyingenzi mumashanyarazi yindege, gifite ibisabwa cyane mubikoresho byo gutunganya.Ifite imiterere yuburemere bworoshye, ubukana bwinshi, kurwanya ubushyuhe, kurwanya okiside no kurwanya ruswa, hamwe nubwiza buhebuje bwa superalloy butuma bwuzuza ibisabwa nibikoresho bya moteri.
Ibikoresho bya superalloy birashobora gukomeza gukora neza mubushyuhe buri hejuru ya 600 ° C no mubihe bimwe na bimwe.Kugaragara kw'ibikoresho bya superalloy ni ukuzuza ibisabwa bikenewe ibikoresho byo mu kirere bigezweho.Nyuma yimyaka y'ubwihindurize bwibintu, superalloys yabaye ibikoresho byingenzi mubikoresho byo mu kirere bikora ibice bishyushye.Dukurikije raporo zijyanye, muri moteri ya aero, Imikoreshereze yacyo irenga kimwe cya kabiri cyibikoresho byose bya moteri.
Muri moteri igezweho ya aero-moteri, gukoresha ibikoresho bya superalloy ni binini cyane, kandi ibice byinshi bya moteri bikozwe hamwe na superalloys, nkibyumba byo gutwika, ibinyabiziga byayobora, ibyuma bya turbine, hamwe na disiki ya turbine, impeta, na nyuma yo gutwika.Ibigize nkibyumba byo gutwika hamwe numurizo wumurizo byakozwe hakoreshejwe ibikoresho bya superalloy.
Gukoresha superalloy muri aeroengine
Hamwe niterambere ryiterambere ryikoranabuhanga hamwe no gukomeza kwiyongera mubushakashatsi, ubushakashatsi kuri rhenium nshya irimo ibyuma bya kristu imwe hamwe na superalloys nshya bizakomeza gushakishwa.Ibikoresho bishya bizongerera imbaraga murwego rwo gukora ibikoresho byo mu kirere ejo hazaza.
1. Ubushakashatsi kuri blade imwe ya kirisiti irimo rhenium
Ubushakashatsi bumwe bwerekanye ko mugihe cyo gutunganya ibikoresho hamwe na kristu imwe ihimbye, imitungo ya alloy hamwe nibintu bitunganyirizwa bigomba kwitabwaho, kubera ko kristu imwe igomba gukoreshwa mubidukikije bikaze, bityo rero ibintu bimwe bivanga hamwe ningaruka zidasanzwe akenshi byongerwa kuri ibikoresho byo kunoza.Indanganturo imwe.Hamwe niterambere rya kristu imwe ya kristu, imiti yimvange yarahindutse.Mubikoresho, niba ibice bya matsinda ya platine (nka Re, Ru, Ir element) byongeweho, ibikubiye mubintu byangiritse W, Mo, Re, na Ta birashobora kwiyongera.Ongera igiteranyo cyibintu bigoye cyane gushonga, kugirango ibintu nka C, B, Hf bishobore guhinduka bivuye kuri "yakuweho" bijya kuri leta "yakoreshejwe";kugabanya ibikubiye muri Cr.Mugihe kimwe, wongeyeho ibindi bintu bivangavanze birashobora gutuma ibikoresho bikomeza gushikama mubikorwa bitandukanye bikenewe.
Gukoresha rheniyumu irimo kristu imwe ya kirisiti irashobora kuzamura cyane ubushyuhe bwayo no kongera imbaraga zo kunyerera.Ongeramo 3% rhenium kumurongo umwe wa kristu hamwe no kongera muburyo bukwiye ibintu bya cobalt na molybdenum bishobora kongera ubushyuhe bwa 30 ° C, kandi imbaraga ziramba hamwe na okiside yangirika bishobora no kuba muburinganire bwiza.leta, bizagirira akamaro kanini ikoreshwa rya rhenium irimo kristu imwe ya kirisiti mu kirere.Gukoresha rhenium irimo ibikoresho bya kristu imwe ya kirisitu ya moteri ya turbine ya moteri ni inzira mugihe kizaza.Icyuma kimwe cya kirisiti gifite ibyiza bigaragara mubijyanye no kurwanya ubushyuhe, imbaraga zumuriro wumuriro, kurwanya okiside no kurwanya ruswa.
2. Ubushakashatsi kuri superalloys nshya
Hariho ubwoko bwinshi bwibikoresho bishya bya superalloy, ibisanzwe ni powder superalloy, ODS alloy, intermetallic compound hamwe nubushyuhe bwo hejuru bwicyuma cyo kwisiga.
Ifu ya superalloy ibikoresho:
Ifite ibyiza byimiterere imwe, umusaruro mwinshi hamwe numunaniro mwiza.
Intermetallic compound:
Irashobora kugabanya uburemere bwibigize no kunoza imikorere, ikwiranye cyane no gukora sisitemu yo gutwara ingufu.
Amavuta ya ODS afite:
Ubushuhe buhebuje bwo hejuru bukora neza, ubushyuhe bwo hejuru bwa okiside irwanya
Ubushyuhe bwo hejuru cyane bushingiye ku kwisiga:
Ikoreshwa cyane cyane kubyara ubushyuhe bwo hejuru bwo kwisiga amavuta, byongera imbaraga zo kwifata kandi byongera ubushobozi bwo gutwara.
Hamwe nogukoresha kwinshi kwa superalloy tubes muri moteri ya aero-moteri, kubisabwa bizakomeza kwiyongera mubirere bizaza.
