Titanium nto khawb kev kho mob

Titanium, vim nws lub teeb yuag, siab zog, thiab corrosion kuj, yog dav siv nyob rau hauv aerospace, kho mob cog, thiab siab - khoom siv. Txawm li cas los xij, nws qhov hardness tsawg ua rau nws yooj yim rau khawb los ntawm kev sib txhuam los yog kev cuam tshuam thaum siv sij hawm ntev -, cuam tshuam rau kev zoo nkauj thiab kev ua haujlwm. Kev kho khawb ntawm titanium nto yuav tsum muaj kev kho kom zoo uas suav nrog khawb qhov tob, cov khoom siv, thiab cov xwm txheej siv. Qhov no restores nto smoothness thaum zam kev puas tsuaj rau lub substrate. Mastering qee cov tswv yim tswv yim tuaj yeem txhim kho kev kho kom zoo.

Rau kev khawb me me, kev saib xyuas niaj hnub thiab kho yooj yim tuaj yeem txhim kho qhov xwm txheej zoo. Rau txhua hnub hnav ntawm titanium alloy watches lossis cov hniav nyiaj hniav kub, yog tias cov kab plaub hau zoo tshwm sim rau saum npoo, siv cov hlau- tshwj xeeb silicone tu daim ntaub nrog dawb polishing compound. Khaws cov ntaub kom qhuav thaum lub sijhawm ua haujlwm thiab maj mam txhuam hauv qhov ncaj, rov qab - thiab - tawm mus rau 15 feeb txhua lub sijhawm, zam dhau lub zog uas tuaj yeem ua rau muaj kab mob. Nov yog qhov ua kom yuam kev me me: Yog tias koj tsis muaj kev tshaj lij polishing ntawm tes, koj tuaj yeem sib tov tshuaj txhuam hniav nrog me me ntawm cov dej qab zib hauv qhov sib piv 3: 1. Tom qab stirring zoo, thov cov sib tov rau ib daim ntaub mos. Cov micro-abrasive particles ntawm baking soda tuaj yeem txhim kho qhov khawb- tshem tawm cov nyhuv, tab sis ceev faj tsis txhob siv lub zog ntau dhau kom tsis txhob muaj kev puas tsuaj ntau dhau. Yog tias koj tsis muaj cov cuab yeej tshaj lij, cov tshuaj txhuam hniav muaj calorie siab tuaj yeem siv los ua ib qho kev hloov pauv ib ntus: noj cov txiv laum huab xeeb - cov tshuaj txhuam hniav loj npaum li cas rau ntawm daim ntaub mos mos thiab maj mam txhuam qhov chaw khawb hauv ib ncig. Tam sim ntawd tom qab ntawd, ua tib zoo ntxuav txhua qhov seem nrog paj rwb ncoo hauv dej ntshiab los tiv thaiv tus neeg sawv cev polishing los ntawm corroding saum npoo. Txoj kev no yog tsim rau kev puas tsuaj nrog khawb tsawg dua 0.1 mm tob. Tom qab kho, qhov saum npoo tuaj yeem rov qab tau daim iav{20}}zoo li ci yam tsis ua rau cov txheej txheem txheej txheej qub.

Kev khawb nruab nrab yuav tsum muaj cov cuab yeej tshaj lij thiab cov txheej txheem kho txheej txheem. Thaum qhov khawb qhov tob tshaj 0.1 hli, peb yuav tsum siv peb - xim polishing sponge block rau kev kho mob. Thawj kauj ruam yog siv 200-grit lub teeb ntsuab abrasive thaiv, siv nws tusyees ntawm lub kaum sab xis ruaj khov raws li cov kev taw qhia ntawm khawb. Tom qab txhua txhua 20 strokes, kho lub kaum sab xis kom paub meej tias txawm tias quab yuam faib. Ib txoj hauv kev tseem ceeb ntawm no yog txau dej me me thaum lub sijhawm ua haujlwm. Qhov no txo ​​cov cua sov uas tsim los ntawm kev sib txhuam, tiv thaiv cov xim ntawm cov titanium nto vim qhov kub thiab txias, thiab tseem txo cov kev sib txhuam ntawm cov abrasive thaiv thiab qhov chaw, uas ua rau muaj kev kho ntau dua. Cov kauj ruam thib ob suav nrog kev rov ua cov txheej txheem nrog 300-grit sky blue abrasive block, siv koj tus ntiv tes los xyuas seb cov npoo khawb puas tsim kev hloov pauv. Thaum kawg, siv 800-grit txiv kab ntxwv abrasive thaiv kom ua kom lub ntsej muag zoo nkauj thiab tshem tawm cov txheej hazy uas tshwm sim los ntawm qhov chaw muaj kev sib txhuam siab. Yog tias cov khib nyiab sib sau ua ke thaum polishing thiab cuam tshuam koj qhov kev pom, ncua cov txheej txheem thiab siv lub tshuab ntxhua khaub ncaws ultrasonic kom tshem tawm cov seem uas siv cov kev vibration siab. Rau cov ntaub ntawv tshwj xeeb xws li cov ntawv sau digital lossis embossed logos, yuav tsum muaj cov txheej txheem rov qab nias: ib qho nyuaj silicone ncoo yog muab tso rau sab nraum qab ntawm qhov chaw, thiab ib qho precision round-headed siab bar yog siv los nias qhov chaw recessed ib tug los ntawm ib tug. Qhov saum npoo smoothness yog rov qab los ntawm cov yas deformation. Txawm li cas los xij, nws yog ib qho tseem ceeb kom tsis txhob yuam kev kho cov qauv nyuaj, uas tuaj yeem deform lub substrate. Thaum lub sijhawm ua haujlwm, cov roj nplua nyeem me me tuaj yeem siv rau ntawm qhov kawg ntawm lub siab bar kom txo kev sib txhuam nrog cov titanium nto thiab tiv thaiv cov khawb tshiab.

Kev puas tsuaj sib sib zog nqus thiab kev kho cov txheej txheem yuav tsum muaj kev sib txuas ntawm cov ntaub ntawv tshawb fawb thiab kev tsim khoom. Thaum khawb nkag mus rau txheej oxide los yog ua rau micro- chipping ntawm cov npoo, qis - ntws epoxy resin filling tuaj yeem ua tiav kev kho seamless. Ua ntej ua haujlwm, qhov tawg ntawm qhov chaw yuav tsum tau ntxuav nrog isopropyl cawv thiab lub tshuab ua haujlwm hlau. Ib lub 0.8 hli columnar epoxy resin yog siv rau qhov chaw puas, flattened nrog kub tweezers, thiab kho rau ib nrab ib teev. Lub 1 hli protrusion tsim tom qab kho tuaj yeem smoothed tawm nrog kev phais scalpel, tom qab ntawd pib polishing kom rov qab smoothness. Cov lus qhia tseem ceeb yog maj mam xuab zeb lub scalpel ntawm cov ntawv xuab zeb ua ntej smoothing kom cov hniav ntse dua thiab cov txheej txheem smoother, txo qis kev puas tsuaj rau titanium nto. Thaum kawg, siv cov kua roj vanish tiv thaiv thiab lub moos muab tso rau hauv qhov cub kom qhuav rau 24 teev. Yog tias qhov kev puas tsuaj nyob ze ntawm cov khoom siv tshwj xeeb xws li lub hnub hloov khawm, laser cladding tshuab yog siv: siab - lub zog laser beam melts titanium alloy hmoov, tsim cov txheej txheem kho uas yog metallurgically sib txuas rau cov khoom siv hauv qhov chaw puas. Cov txheej no muaj qhov tawv tawv ntawm HV500 lossis siab dua, thiab qhov kub siab- thaj tsam cuam tshuam tsawg dua 0.5mm, tiv thaiv deformation ntawm cov khoom nyob ib sab vim qhov kub thiab txias. Rau kev puas tsuaj loj heev uas tsis tuaj yeem kho tau, hloov lub rooj zaum saib yog qhov kev daws teeb meem kawg. S1-qib qhov chaw nrog laser los tiv thaiv- cov qauv dej ripple cuav yuav tsum raug xaiv los xyuas kom meej tias lub moos kho tau dhau ntawm peb- tes kev sib koom tes thiab qhov ntsuas cua helium-filled airtightness.

Los ntawm kev tiv thaiv kev xav, kev tu txhua hnub thiab kev siv tus cwj pwm ntawm cov khoom titanium ncaj qha cuam tshuam rau lub neej ntev. Txhawm rau tiv thaiv kev sib cuag ncaj qha nrog cov khoom tawv xws li cov yuam sij thiab pob zeb, siv ib lub hnab mos los yog cov ntaub ntawv cais rau kev cia kom txo qis kev sib tsoo ntau dua 80%. Rau siab- yuav tsum muaj daim ntawv thov xws li kev cog lus kho mob lossis cov khoom siv dav hlau, micro- arc oxidation thev naus laus zis tuaj yeem siv rau hauv theem pretreatment deg: siv high-voltage pulses rau cov electrolyte ua rau cov porous oxide zaj duab xis tsim rau ntawm titanium nto. Lub microstructure nrog pore qhov ntau thiab tsawg ntawm 1-10 ​​micrometers txhim kho txheej adhesion thiab txhim kho osseointegration kev ua tau zoo ntawm kev cog hniav los ntawm kev thauj khoom bioactive yam xws li pob txha morphogenetic proteins (BMPs). Hauv cov khoom siv hluav taws xob, lub cev vapor deposition (PVD) thev naus laus zis tuaj yeem tso cov titanium nitride (TiN) lossis pob zeb diamond zoo li carbon (DLC) txheej ntawm titanium nto. Cov yav tas muaj ib tug golden luster thiab ib tug hardness ntawm HV2000-2500, thaum lub tom kawg muaj ib tug tsawg coefficient ntawm kev sib txhuam ntawm 0.05-0.1, ob qho tib si ho txhim kho nto hnav kuj thiab khawb kuj.

Kev kho khawb ntawm qhov chaw titanium yuav tsum sib npaug ntawm kev kho kom zoo nkauj thiab kev tiv thaiv kev ua haujlwm. Los ntawm kev saib xyuas txhua hnub mus rau kev kho kev tshaj lij, los ntawm kev hloov kho cov khoom siv rau kev tsim kho tshiab, txhua kauj ruam yuav tsum muaj kev tswj xyuas meej ntawm cov txheej txheem kev ua haujlwm thiab cov txheej txheem ua haujlwm. Mastering cov kev txawj ntse no tuaj yeem tsis tsuas yog txuas ntxiv lub neej kev pab cuam ntawm cov khoom titanium, tab sis kuj ua kom lawv cov txiaj ntsig zoo xws li lub teeb yuag thiab kev tiv thaiv corrosion, muab kev txhawb zog siab rau siab -kev tsim khoom thiab kev noj qab haus huv.
