3. Muaj ob hom titanium ntsia hlau ua: kub taub hau thiab machining. Machining titanium screws feem ntau tsim nrog GR5 6al4v titanium. Qhov laj thawj tseem ceeb yog qhov no titanium alloy muaj siab hardness thiab zoo txhua yam khoom, uas yog tsim nyog rau machining. Lub taub hau kub yog feem ntau yog ntuj tsim, yog li nws yuav tsum tau hais tias cov khoom yuav tsum tsis txhob nyuaj heev. Ntawm cov titanium, qib 2 thiab qib 4 titanium yog qhov tsim nyog rau cov lus kub. GR4 Ti screws feem ntau ua tiav los ntawm cov lus kub. Gr2 GR4 titanium muaj ib qho kev ntxhib los mos, nrog lub zog ntev ntawm ntau dua 400MPa rau 100h ntawm 350 degree, thiab muaj cov yas zoo thaum ua haujlwm kub.
Qhia nthuav dav
4. Cov titanium screws ua tiav los ntawm cov lus kub yog tus nqi ntau dua ntawm cov khoom siv thiab thev naus laus zis, tab sis cov titanium screws ua tiav los ntawm machining yog qhov zoo tshaj qhov txias taub hau titanium screws nyob rau hauv cov nqe lus ntawm cov tsos thiab precision. Tom qab tag nrho, qhov tseeb ntawm titanium screws ua los ntawm machining tuaj yeem raug rau 0.01mm.
5. Cov uas twb muaj lawm gr4 ti screws thiab titanium alloys feem ntau yog siv los tsim cov qib siab saib qhov chaw, hniav nyiaj hniav kub, spectacle thav ntawv, thiab lwm yam khoom zoo nkauj. Txhawm rau ua kom lub ntsej muag ntshiab titanium lossis titanium alloy muaj zog dua thiab gloss, kev kho hardening feem ntau yog ua los ntawm cov ntshiab titanium lossis titanium alloy. Cov txheej txheem saum npoo tawv uas twb muaj lawm ntawm cov ntshiab titanium lossis titanium alloy yog raws li hauv qab no:
| 1) | Atmospheric thermal oxidation kev kho mob: ncaj qha tshav kub ntshiab titanium los yog titanium alloy qhov chaw nyob rau hauv cov huab cua los ntawm 750 degree mus rau 1000 degree, thiaj li hais tias ib txheej ntawm rutile crystalline titanium dioxide (rutile) yog tsim nyob rau saum npoo ntawm ntshiab titanium los yog titanium alloy, thiab nto. hardness yuav ncav cuag hv1100. Txawm li cas los xij, oxide txheej ua los ntawm txoj kev no nthuav tawm cov xim grey, tsis muaj xim hlau ci, thiab ib qho ntxhib saum npoo. Thaum siv rau cov khoom lag luam dav dav, kev kho mob tom qab feem ntau yog xav tau |
| 2) | Atmospheric thermal oxidation ntxiv rau kev kho lub tshuab nqus tsev: cov ntshiab titanium los yog titanium alloy qhov chaw tom qab atmospheric thermal oxidation kev kho mob yog ntxiv rau hauv lub tshuab nqus tsev kho cua sov rau lub sij hawm ntawm 750 degree thiab 850 degree, thiaj li mus crystallize thiab decompose lub titanium dioxide. nyob rau saum npoo, thiab tsim cov pa oxygen kom diffuse mus rau hauv cov qauv crystalline ntawm ntshiab titanium los yog titanium alloy, thiaj li yuav ua rau cov khoom sib tov hardening nyhuv ntawm cov hlau puag, lub siab dua cov ntsiab lus ntawm cov pa, lub hardness ntau dua, tab sis txoj kev no yuav ua rau. lub coarsening ntawm cov khoom siv lead ua, uas yuav txo tau qhov chaw tiav thiab tsis yooj yim rau polish. |
| 3) | Nqus thermal oxidation nitriding diffusion kev kho mob: nitrogen thiab ib qho kev faib ua feem ntawm oxygen los yog dej vapor yog nkag mus rau hauv lub tshuab nqus tsev vacuum, thiab qhov kub thiab txias yog khaws cia ntawm 700 degree ~ 800 degree nyob rau hauv tsau lub tshuab nqus tsev siab rau ib lub sij hawm ntawm lub sij hawm, kom cov nitrogen thiab oxygen diffuse mus rau hauv crystalline qauv ntawm ntshiab titanium los yog titanium alloy, uas ua rau ib tug hardening txheej ntawm nitrogen-oxygen khoom tov ntawm ib tug tej thickness nyob rau saum npoo ntawm ntshiab titanium los yog titanium alloy qhov chaw, txoj kev no yuav obviously txhim kho cov nplej coarsening thiab nto roughness. nyob rau hauv txoj kev 2, tab sis qhov piv ntawm nitrogen rau oxygen los yog dej vapor thiab kub kho kub yuav tsum tau ua tib zoo tswj nyob rau hauv tus txheej txheem, txwv tsis pub lub nto discoloration thiab roughness ntawm ntshiab titanium los yog titanium alloy yuav tshwm sim. |
| 4) | Ion nitriding txoj kev: tso cov ntshiab titanium los yog titanium alloy qhov chaw rau hauv lub tshuab nqus tsev vacuum, siv high voltage, thiab qhia nitrogen los tsim nitrogen ions. Nitrogen ions tau nyiam los ntawm cov electrode tsim los ntawm cov ntshiab titanium los yog titanium alloy, cuam tshuam cov electrode nto ntawm kev kub ceev, tsim kom muaj qhov kub thiab txias, txhawb cov nitrogen atoms kom nkag mus rau hauv titanium hlau puag cov khoom, thiab tsim cov tshuaj tiv thaiv rau saum npoo, ib txheej diffusion. muaj nitrogen thiab titanium nitride compound txheej yog tsim rau saum npoo ntawm titanium hlau. Nyob rau hauv txoj kev no, ntxiv rau qhov infiltration ntawm nitrogen atoms rau hauv cov ntshiab titanium los yog titanium alloy, titanium nitride siv lead ua txheej kuj tsim rau saum npoo. Yog li ntawd, qhov hardness yog ntau dua li ntawm txoj kev oxidation, tab sis nws yuav ua rau kom lub ntsej muag roughness ntawm ntshiab titanium los yog titanium alloy. |
| 5) | Nqus lub cev evaporation txoj kev: ib txheej ntawm cov zaj duab xis yog ncaj qha plated nyob rau saum npoo ntawm ntshiab titanium los yog titanium alloy los ntawm lub tshuab nqus tsev evaporation txoj kev. Txawm hais tias txoj kev no tsis ua rau lub ntsej muag roughness ntawm cov ntshiab titanium los yog titanium alloy, vim cov txheej txheej tuab, nws tsis tuaj yeem muab kev ua tau zoo hardening rau cov mos substrate ntawm ntshiab titanium los yog titanium alloy. |
