Plaub-kauj ruam txoj kev rau kev kho deg ntawm titanium alloy forgings: sandblasting, casting, sib tsoo, thiab xim
Qhov ceev ntawm titanium alloy yog me me, yog li lub inertia ntawm cov kua titanium yog me me thaum ntws. Lub fluidity ntawm molten titanium yog qhov tsis zoo, uas ua rau qis casting txaus tus nqi. Qhov sib txawv ntawm qhov kub thiab txias pwm (300 degree) yog qhov loj thiab qhov txias yog ceev. Lub casting yog nqa tawm nyob rau hauv ib qho chaw tiv thaiv. Cov teeb meem xws li qhov pores yuav inevitably tshwm sim rau saum npoo thiab sab hauv ntawm titanium castings, uas muaj kev cuam tshuam zoo rau qhov zoo ntawm titanium castings. Cov hauv qab no piav qhia txog titanium alloy forgings. txoj kev kho saum npoo.
Kev tshem tawm cov txheej txheem txheej txheej
Cov txheej txheej txheej txheej txheej yog qhov tseem ceeb cuam tshuam rau lub cev thiab tshuaj lom neeg ntawmtitaniumcastings. Ua ntej kev sib tsoo thiab polishing titanium castings, txheej txheej txheej yuav tsum tau muab tshem tawm kom ua tiav cov nyhuv polishing txaus. Cov txheej txheej txheej txheej ntawm titanium tuaj yeem raug tshem tawm tag nrho los ntawm sandblasting ua raws los ntawm pickling.
1. Sand blasting: Rau xuab zeb blasting ntawmtitanium castings, feem ntau nws yog qhov zoo dua los siv dawb corundum ntxhib blasting. Cov xuab zeb blasting siab yog me dua li cov hlau tsis muaj nuj nqis thiab feem ntau tswj tau qis dua 0.45Mpa. Vim tias thaum txhaj tshuaj siab dhau lawm, cov xuab zeb tuaj yeem cuam tshuam rau ntawm titanium nto thiab tsim cov nplaim taws. Qhov kub nce tuaj yeem hnov mob nrog titanium nto, tsim cov pa phem thib ob thiab cuam tshuam rau qhov zoo ntawm qhov chaw. Lub sij hawm yog 15 mus rau 30 vib nas this, thiab tsuas yog cov xuab zeb adhering, nto sintered txheej thiab ib feem ntawm oxide txheej nyob rau saum npoo ntawm casting raug tshem tawm. Tus so ntawm cov tshuaj tiv thaiv txheej txheej txheej yuav tsum tau muab tshem tawm sai sai los ntawm cov tshuaj pickling.
2. Pickling: Pickling tuaj yeem tshem tawm sai thiab tshem tawm cov txheej txheem txheej txheej tsis muaj kab mob los ntawm lwm cov khoom ntawm qhov chaw. Ob qho HF-HCl thiab HF-HNO3 pickling daws yuav siv tau rau pickling titanium, tab sis HF-HCl pickling tov muaj ib tug loj hydrogen nqus peev xwm, thaum lub HF-HNO3 pickling kua muaj ib tug me me hydrogen nqus peev xwm thiab muaj peev xwm tswj HNO3 concentration. ntawm HF txo qhov nqus hydrogen thiab tuaj yeem ci ntsa iab. Feem ntau, cov concentration ntawm HF yog li ntawm 3% mus rau 5%, thiab cov concentration ntawm HNO3 yog li ntawm 15% mus rau 30%.
Kev kho qhov tsis xws luag casting
Internal pores thiab shrinkage kab noj hniav tuaj yeem raug tshem tawm los ntawm kub isostatic nias, tab sis nws yuav cuam tshuam qhov tseeb ntawm cov hniav hniav. Nws yog qhov zoo tshaj plaws los siv X-ray qhov teeb meem nrhiav pom, tom qab ntawd zom qhov chaw kom nthuav tawm cov pores, thiab siv laser kho vuam. Deg pore tsis xws luag tuaj yeem kho ncaj qha los ntawm laser vuam hauv zos.
Sib tsoo thiab polishing
1. Kev sib tsoo tshuab: titanium muaj cov tshuaj lom neeg ua haujlwm siab, tsis tshua muaj thermal conductivity, siab viscosity, tsis tshua muaj neeg sib tsoo piv, thiab yooj yim rau cov tshuaj abrasives. Ordinary abrasives tsis haum rau kev sib tsoo thiab polishing titanium. Nws yog qhov zoo tshaj plaws los siv abrasives nrog zoo thermal conductivity. Rau super-hard abrasives, xws li pob zeb diamond, cubic boron nitride, thiab lwm yam, polishing linear ceev yog feem ntau 900 ~ 1800m / min. Txwv tsis pub, kev sib tsoo kub hnyiab thiab micro-cracks yuav yooj yim tshwm sim ntawm titanium nto.
2. Tshuaj polishing: Tshuaj polishing ua tiav lub hom phiaj ntawm qib thiab polishing los ntawm oxidation-txo cov tshuaj tiv thaiv ntawm cov hlau hauv tshuaj lom neeg. Qhov zoo dua yog tias tshuaj polishing tsis muaj dab tsi cuam tshuam nrog lub hardness ntawm cov hlau, polishing cheeb tsam, thiab cov qauv tsim. Txhua qhov chaw nyob rau hauv kev sib cuag nrog cov kua polishing yog polished. Tsis tas yuav tsum muaj cov cuab yeej tshwj xeeb nyuaj, thiab kev ua haujlwm yooj yim. Nws yog tsim nyog rau polishing titanium hniav hniav brackets nrog complex qauv. Txawm li cas los xij, cov txheej txheem tsis zoo ntawm cov tshuaj txhuam hniav yog qhov nyuaj rau kev tswj, thiab nws yuav tsum muaj cov nyhuv polishing zoo ntawm cov hniav hniav tsis cuam tshuam qhov tseeb ntawm cov hniav hniav.
Xim xim
Txhawm rau txhawm rau txhim kho kev zoo nkauj ntawm titanium hniav nyiaj hniav kub thiab tiv thaiv kom tsis txhob muaj xim ntawm titanium hniav nyiaj hniav kub los ntawm txuas ntxiv oxidation nyob rau hauv tej yam kev mob, nto nitriding, atmospheric oxidation thiab anodizing yuav siv tau los xim rau saum npoo los tsim ib lub teeb daj los yog golden daj xim, yog li kev txhim kho lub durability ntawm titanium hniav hniav. Kev zoo nkauj. Txoj kev anodizing siv qhov cuam tshuam ntawm lub teeb los ntawm titanium oxide zaj duab xis los tsim cov xim ntuj. Cov xim muaj yeeb yuj tuaj yeem tsim rau ntawm qhov chaw titanium los ntawm kev hloov lub cell voltage.
