Daim ntawv thov ntawm Titanium Alloy Txhaj Moulding Pub hauv Aerospace

Nyob rau xyoo 1970s, tom qab kev vam meej ntawm MIM, nyob rau hauv aerospace teb, nyob rau hauv lig 1970s, tom qab kev vam meej thaum ntxov ntawm MIM, nyob rau hauv lub aerospace teb, MIM tau thov. Nov yog qee qhov piv txwv: lub rooj zaum txoj siv sia, cov khoom siv xauv thiab cov khoom siv, cov roj txhaj tshuaj nozzles thiab cov hniav kho cov pas nrig.

Tsis tas li ntawd, nyob rau hauv xyoo tas los no, tib neeg tau pib siv cov khoom siv high-temperature alloy uas tsim los ntawm MIM txheej txheem rau aeroengines. Cov ntaub ntawv tseem ceeb MIM siv hauv kev lag luam aviation muaj xws li stainless hlau (316L, 410, 420/17-4PH, 13-8PH), superalloys (Hastelloy X, Inconel 713, Inconel 718, Nimonic{{8} } thiab Udimet 700), thiab titanium alloys TIAL thiab Ti{10}}AL-4V.

(1) Lub rooj zaum siv qhov chaw

Qhov loj ntawm lub zog siab MIM lub rooj zaum siv nyob rau hauv aerospace teb yog 90g. Qhov no nrog cov duab complex yog ua los ntawm Fe-7Ni-0.6C alloy steel. Tom qab kev kho cua sov, lub zog tensile ntau dua 200Mpa.

Feem ntau, qhov chaw ntawm qhov loj me no (80mm inch) thiab qhov loj yog dhau ntawm MIM qhov chaw. Txawm li cas los xij, vim yog qhov nyuaj ntawm cov khoom, tsuas yog MIM txheej txheem yog txoj kev tsim khoom lag luam tshaj plaws.

(2) Lub rooj zaum siab ntawm cov roj qhov hluav taws xob valve

Qhov me me MIM siv hauv A380 Airbus yog roj qhov hluav taws xob valve compression lub rooj zaum. Cov khoom siv no yog tsim los ntawm stamping hlau qhov chaw, txiav ncej, ntxhua khaub ncaws, txiv ntseej thiab lwm yam. Tam sim no lawv tau hloov los ntawm ob qhov MIM: MIM-316L stainless hlau qhov chaw los kho cov dej khov tiv thaiv, thiab ib feem ntawm MIM nrog ib qho notch nyob rau sab saum toj ntawm tus ncej los kho cov yas hloov hauv qhov chaw.

Qhov no txuag tau ntau tus nqi tsim khoom, thiab tsis tsuas yog txo tus nqi ntawm cov khoom, tab sis kuj txuag lub sijhawm sib dhos thiab cov nqi tsim khoom rau kev npaj ntau yam.
