Cov khoom thiab kev siv ntawm Gr12 titanium alloy forgings

Gr12 titanium forgings muaj lub zog siab, tsis tshua muaj ntom, zoo txhua yam khoom, zoo toughness thiab corrosion kuj. Tsis tas li ntawd, titanium forgings muaj cov txheej txheem tsis zoo, tsis yooj yim rau kev txiav, thiab yooj yim nqus hydrogen, oxygen, nitrogen, carbon thiab lwm yam impurities thaum ua kub. Tsis tas li ntawd, kev hnav tsis zoo thiab cov txheej txheem ntau lawm. Kev lag luam tsim khoom ntawm titanium pib hauv 1948. Nrog rau kev txhim kho ntawm kev lag luam aviation, titanium kev lag luam loj hlob ntawm qhov nruab nrab txhua xyoo ntawm kwv yees li 8%. Tam sim no, cov khoom tsim tawm txhua xyoo ntawm titanium forgings tau mus txog ntau dua 40, 000 tons, titanium forgings ze li 30 hom. titanium forgings yog Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) thiab muaj titanium ntshiab (TA1, TA2 thiab TA3) .

Titanium forgings feem ntau yog siv rau hauv kev tsim cov khoom siv rau cov tshuab dav hlau, ua raws li cov khoom siv rau cov foob pob hluav taws, cov cuaj luaj thiab cov dav hlau ceev ceev.Nyob rau hauv nruab nrab -1960s, titanium thiab nws cov alloys tau siv nyob rau hauv kev lag luam, xws li Raws li kev tsim cov khoom siv hluav taws xob rau kev lag luam electrolysis, condensers rau cov chaw nres tsheb fais fab, cov cua sov rau cov roj refining thiab desalination, thiab cov khoom siv hluav taws xob ib puag ncig. Titanium thiab titanium alloys tau dhau los ua cov khoom siv corrosion-resistant. Tsis tas li ntawd, nws yog siv los tsim hydrogen cia cov ntaub ntawv thiab cov duab nco alloys.

Kev kho deg: tig, chamfering

Nto zoo: lub ntsej muag roughness Ra ntawm ob lub ntsej muag kawg yuav tsum tsis pub ntau tshaj 3.2m (raws li qhov yuav tsum tau muaj kev kuaj xyuas ultrasonic), qhov roughness Ra ntawm sab hauv thiab sab nrauv yuav tsum tsis pub tshaj 12.5m (Ra yuav tsum yog tsis pub ntau tshaj 3.2 m ncig yuav tsum tau rau cylindrical ultrasonic flaw detection), lub chamfering vojvoog yuav tsum yog 5 ~ 15mm. yuav tsum tsis txhob muaj qhov pom kev tsis zoo ntawm qhov chaw ntawm cov khoom, xws li cov kab nrib pleb, wrinkles, ob chav tawv nqaij, thiab lwm yam. Qhov saum npoo ntawm cov khoom yuav tsum du thiab du, thiab cov khoom ntawm cov khoom yuav tsum du thiab du. Cov chaw hauv cheeb tsam tuaj yeem raug tshem tawm los ntawm kev sib tsoo, kev tu qhov tob yuav tsum tsis txhob siab tshaj qhov loj me, thiab yuav tsum yog me me tso cai. Qhov sib piv ntawm kev ntxuav qhov tob rau qhov dav ntawm ob lub ntsej muag kawg yuav tsum tsis txhob ntau tshaj 1: 6, thiab sab hauv thiab sab nrauv yuav tsum tsis txhob ntau tshaj 1: 10. Kev sib tsoo sab nrauv yuav tsum tau nqa tawm hauv axial kev taw qhia.
