Qhov ceev ntawm titanium alloy yog tsawg, yog li lub inertia ntawm titanium kua thaum lub sij hawm ntws yog me me. Qhov tsis zoo fluidity ntawm molten titanium ua rau tus nqi qis casting. Muaj qhov sib txawv tseem ceeb (300 degree) ntawm qhov kub thiab txias ntawm pwm thiab txias yog ceev. Qhov tsis tuaj yeem muaj qhov tsis xws luag xws li pores ntawm qhov chaw thiab sab hauv ntawm titanium castings yuav tshwm sim. Qhov no muaj feem cuam tshuam rau qhov zoo ntawm titanium castings. Rau qhov teeb meem no, peb tuaj yeem siv plaub txoj kev kho saum npoo nram qab no: Sandblasting, casting, sib tsoo, xim
Kev tshem tawm cov txheej txheem txheej txheej saum npoo
Cov txheej txheem saum npoo av is yog qhov tseem ceeb cuam tshuam rau lub cev thiab tshuaj lom neeg ntawm titanium castings. Ua ntej cov titanium castings yog hauv av thiab polished, nws yog ib qho tsim nyog yuav tsum tshem tawm tag nrho cov txheej txheem deg kom ua tiav cov nyhuv polishing txaus. Cov txheej txheem txheej txheej ntawm titanium tuaj yeem raug tshem tawm tag nrho los ntawm txoj kev sandblasting ua raws li kev ntxuav cov kua qaub.
Sandblasting: Rau kev kho sandblasting ntawm titaniumcastings, ntxhib dawb corundum feem ntau yog qhov kev xaiv. Lub siab ntawm sandblasting feem ntau qis dua 0.45 Mpa. Thaum cov xuab zeb blasting siab dhau lawm, cov xuab zeb tuaj yeem cuam tshuam rau titanium nto, ua rau muaj qhov hnyav heev. Qhov kub nce ntxiv yuav ua rau muaj kuab paug thib ob thiab cuam tshuam rau qhov zoo ntawm qhov chaw. Lub sij hawm sandblasting yuav tsum tau tswj tsis pub dhau 15 mus rau 30 vib nas this. Nws tsuas yog tsim nyog los tshem tawm cov xuab zeb adhered, txheej txheej sintering, thiab qee cov oxide txheej rau ntawm qhov chaw casting. Qhov seem txheej txheej txheej txheej txheej txheej txheem tuaj yeem raug tshem tawm sai sai los ntawm kev siv cov tshuaj ntxuav cov kua qaub.
Pickling: Pickling tuaj yeem tshem tawm sai thiab tshem tawm cov txheej txheem saum npoo, thiab tsis muaj lwm cov ntsiab lus yuav kis tau rau ntawm qhov chaw. Ob lub HF-HCl series thiab HF-HNO3 series ntawm pickling daws yuav siv tau rau pickling ntawm titanium, tab sis cov HF-HCl series pickling kua muaj ib tug ntau dua hydrogen nqus peev xwm, thaum lub HF-HNO3 series pickling kua muaj ib tug tsawg dua hydrogen absorption peev. Kev nqus dej tuaj yeem txo qis los ntawm kev tswj hwm qhov concentration ntawm HNO3, thiab qhov chaw tuaj yeem kho kom zoo nkauj. Feem ntau, qhov concentration ntawm HF yog nyob ib ncig ntawm 3% mus rau 5%, thiab cov concentration ntawm HNO3 yog nyob ib ncig ntawm 15% mus rau 30%.
Kev kho qhov tsis xws luag casting
Internal pores thiab shrinkage kab noj hniav yog cov tsis xws luag sab hauv uas tuaj yeem raug tshem tawm los ntawm cov txheej txheem kub isostatic nias, tab sis lawv tuaj yeem cuam tshuam qhov raug. Nws yog qhov zoo dua los ua X-ray tshuaj xyuas, tom qab ntawd zom tawm ntawm qhov chaw kom nthuav tawm cov pores, thiab siv laser vuam los kho. Deg pore defects tuaj yeem kho ncaj qha los ntawm laser vuam hauv zos.
Sib tsoo thiab polishing
Mechanical sib tsoo: chemical reKev ua haujlwm ntawm Titanium yog siab, thermal conductivity tsawg, thiab viscosity siab. Lub tshuab sib tsoo thiab sib tsoo yog qhov tsawg, thiab nws yooj yim rau hnov mob nrog cov cuab yeej abrasive. Cov khoom siv abrasive feem ntau tsis zoo rau kev sib tsoo thiab polishing titanium. Nws yog qhov zoo tshaj plaws los siv super- tawv abrasives nrog zoo thermal conductivity, xws li pob zeb diamond thiab cubic boron nitride. Txoj kab polishing ceev yog zoo dua los ntawm 900 txog 1800 m / min. Txwv tsis pub, lub titanium nto yog feem ntau sib tsoo kub hnyiab thiab micro tawg.
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 cov tshuaj nruab nrab. Nws qhov zoo dua yog tias cov tshuaj polishing yog ywj siab ntawm qhov hardness ntawm cov hlau, polishing cheeb tsam thiab cov qauv tsim. Txhua feem ntawm kev sib cuag nrog cov tshuaj polishing yog polished. Tsis tas yuav tsum muaj cov cuab yeej tshwj xeeb thiab nyuaj. Kev ua haujlwm yog yooj yim thiab nws yog qhov tsim nyog rau polishing complex-cov txheej txheem titanium hniav nyiaj hniav kub. Txawm li cas los xij, cov txheej txheem tsis zoo ntawm cov tshuaj polishing yog qhov nyuaj los tswj. Nws yog qhov yuav tsum tau ua kom tiav cov nyhuv polishing zoo ntawm cov hniav hniav yam tsis muaj kev cuam tshuam qhov tseeb ntawm cov hniav hniav.
Xim xim
Txhawm rau txhim kho qhov zoo nkauj ntawm titanium forgings thiab tiv thaiv ntxiv oxidation thiab discoloration ntawm forgings nyob rau hauv tej yam kev mob, nto nitriding kev kho mob, atmospheric oxidation, thiab anodizing nto xim txoj kev yuav ua hauj lwm. Cov txheej txheem no ua rau lub teeb daj lossis xim daj rau ntawm qhov chaw, yog li txhim kho cov tsos ntawm qhov chaw. Txoj kev anodizing siv qhov cuam tshuam cuam tshuam ntawm oxide zaj duab xis ntawm titanium los tsim cov xim. Los ntawm kev hloov lub da dej voltage, ntau yam xim tuaj yeem tsim rau ntawm titanium nto.
