Cov khoom lag luam
Titanium Alloy Qib 12 yog qhov muaj feem cuam tshuam rau cov npib tsib xee thiab molybdenum, uas txhim kho cov khoom siv tau zoo dua li kev lag luam cov qib. Nws yog siv hauv kev txo qis lossis hloov kho. Tshwj xeeb, nws yog siv hloov ntawm cov lag luam cov qib kawm (piv txwv li qhov zoo dua rau cov brines kub, thiab qhov twg lub zog ntxiv tso cai rau kev siv cov ntu sib zog.
Nyob rau hauv chav tsev kub, nws yog alpha alloy thiab yuav muaj cov nyiaj tsawg ntawm beta theem. Nws hloov mus rau Beta theem ntawm 890℃± 15 degree
Titanium yog reactive, thiab muaj kev sib txawv heev rau cov pa oxygen, uas ua rau cov tawv nqaij ntawm ruaj khov thiab zoo heev oxide. Cov tawv nqaij muab cov khoom siv corrosion zoo tshaj plaws, txawm tias muaj kev cuam tshuam ntawm cov hlau. Cov ntaub ntawv oxide txheej ntaug nthawv thiab raug rau cov cua. Txawm li cas los xij, thaum niam txiv tshiab yog kis rau cov kev mob uas tsis muaj mob lossis tsis muaj huab cua, kev xeb sai yuav tshwm sim. Kev saib xyuas kuj yuav tsum tau noj yog titanium yog ua haujlwm nyob hauv hydrogenlement los ntawm hydrogride embrittlement tuaj yeem ua kom muaj zog, nrog ploj ntawm kev sib tw.
Muaj Muaj Cov Titanium Alloy
Gnee tuaj yeem muab cov khoom siv titanium alloy 12 raws li phaj, ntawv thiab sawb thiab welded yeeb nkab, seamless thiab welded raj, zam billet thiab zam txim.
Corrosion tsis kam ntawm titanium alloy
Titanium alloys tau siv dav lawm vim lawv cov kev tiv thaiv corrosion zoo heev, tshwj xeeb hauv chloride daws. Qhov sib ntxiv ntawm npib tsib xee thiab molybdenum mus rau qib 12 titanium muab nws zoo tshaj plaws ntshiab ua rau kev lag luam ntshiab 2 titanium alloys, thaum tseem muaj zog ntxiv nws lub zog. Thaum cov qib no muaj ntau lub corrosion tsis zoo rau palladium {}}}}}} Alloy athoy distorance nyob rau hauv kub chloride daws teeb meem. Titanium alloys kuj muab cov kev tiv thaiv zoo heev rau cov dav corrosion, nrog corrosion ploj cov nqi qis dua 0.04 mm / xyoo.

Fabrication nrog titanium alloy
Titanium Alloy Qib 12 yog forged conventionally, nyob rau hauv qhov cub nqaim ntau yam 815 - 900 degree. Titanium thiab titanium alloys feem ntau nyuaj dua li ob qho tib si txhuas thiab tag nrho lawv cov siab tawv siab thiab nce nrawm ntawm lub zog nrog kev poob kub. Kub Forging tawm nplooj tuab, tawv sab nraud ntawm titanium oxide rau saum npoo. Cov txheej no yog hu ua "Alpha rooj plaub" thiab feem ntau tau muab tshem tawm los ntawm pickling hauv kev sib tov ntawm nitric thiab hydrofluoric acids. Raws li cov khoom siv, titanium alloys feem ntau yog qhia thiab pickled, thiab tuaj yeem yooj yim txias tsim nyob rau hauv cov tshuab siv cov qauv. Nyob rau hauv txias txoj kev sib tw "alpha rooj plaub" tsis xav tau thiab ntxiv mus rau lwm tus, tsuas yog tshem tawm cov hlau siv hluav taws xob hauv qhov chaw, uas tuaj yeem ua rau pitting corrosion.
