Polishing ntawm titanium alloy cov khoom

Kev ntxuav yog qhov tseeb ntawm kev tshem tawm cov imperfections thiab lopsidedness ntawm txheej txheej ntawm titanium composites thiab ua haujlwm ntawm qhov ua tiav thiab qhov sib npaug. Lub hauv paus yog vim li cas rau titanium kev sib xyaw ua ke tu yog ua haujlwm ntawm nws qhov zoo ntawm qhov chaw thiab kev xav, txawm li cas los xij ntxiv txhim kho nws qhov kev yaig qhov cuam tshuam thiab biocompatibility.

Titanium yog lwm hom hlau. Cov khoom ntawm titanium txuas nrog cov khoom ntawm cov pa phem xws li carbon, nitrogen, hydrogen, thiab oxygen. Qhov zoo tshaj plaws titanium iodide muaj cov pa phem ntawm qee yam xws li 0.1%, txawm li cas los xij nws txoj kev sib koom siab yog tsawg thiab nws cov plliancy siab. Cov khoom ntawm 99.5% niaj hnub unadulterated titanium yog: thickness ρ=4.5g/cubic centimeter, liquefying point 1725 degree, sov conductivity λ=15.24W/(m. K), rigidity σb{{9 }}MPa, ncab δ=25%, hla cheeb tsam Shrinkage ψ=25%, ntau yam modulus E=1.078 × 105MPa, hardness HB195.

Titanium muaj tshuaj lom neeg muaj zog, tsis tshua muaj thermal conductivity, siab viscosity, tsis tshua muaj neeg sib tsoo piv, thiab yooj yim rau react nrog abrasives. Ordinary abrasives tsis haum rau kev sib tsoo thiab polishing titanium. Nws yog qhov zoo tshaj plaws los siv superhard abrasives nrog zoo thermal conductivity. Xws li pob zeb diamond, cubic boron nitride, thiab lwm yam., polishing log ceev yog feem ntau 900 ~ 1800m / min. Txwv tsis pub, kev sib tsoo kub hnyiab thiab micro-cracks yog nquag tshwm sim ntawm titanium nto. Tag nrho cov titanium alloy hniav nyiaj hniav kub, saib pluaj, bracelets thiab lwm yam khoom siv titanium alloy muaj qee qhov teeb meem hauv polishing. Cov ntaub ntawv tshwj xeeb polishing yog xav tau los txhuam qhov chaw ci ntsa iab.

Lub thermal conductivity ntawm titanium yog λ=15.24W/(mK), uas yog hais txog 1/4 ntawm nickel, 1/5 ntawm hlau, thiab 1/14 ntawm txhuas. Lub thermal conductivity ntawm ntau yam titanium alloys yog li 50% qis dua li ntawm titanium. . Lub elastic modulus ntawm titanium alloy yog hais txog 1/2 ntawm cov hlau, yog li nws tsis muaj zog rigidity thiab yooj yim rau deform. Nws tsis haum rau ua cov pas nrig thiab nyias-walled qhov chaw. Tus nqi rov qab ntawm lub tshuab ua haujlwm thaum txiav yog qhov loj heev, li 2 mus rau 3 npaug ntawm cov hlau tsis muaj steel. sij hawm. Yog li muaj qee qhov nyuaj ntawm polishing.

Titanium alloy polishing txheej txheem

1. Deg pretreatment: Siv pickling, electrolytic tu thiab cov tswv yim sib txawv kom tshem tawm nto xeb, oxide txheej thiab lwm yam khoom ua kom puas ntsoog kom lub nto zoo meej thiab du.

2. Kev Sib Tsoo: Siv cov tshuab lossis phau ntawv crushing kom tshem tawm cov burrs, lopsided lopsidedness nyob rau theem sab saum toj.

3. Polishing: Siv cov khoom siv tu lossis tshuaj ntxuav kom ua haujlwm ntawm cov txheej txheem ua tiav mus rau qib tshwj xeeb.

4. Sandblasting: Txau abrasives nyob rau hauv ib tug superficial theem kom tshem tawm cov av thiab deformities ntawm ib tug superficial theem.

5. Kev Tu: Ntxuav nrog dej los yog teb rau kev tshem tawm cov xuab zeb blasting ntxhib thiab tu cov kws tshwj xeeb tso nyiaj kom lav qhov saum npoo zoo meej thiab du.

6. Kev kho deg: Raws li ntau yam yuav tsum tau ua thiab siv, qhov saum npoo yog electroplated, anodized, thiab lwm yam. txhawm rau txhim kho nws txoj kev yaig tawm tsam thiab txhim kho.

Mechanical polishing (coarse polishing, nruab nrab polishing, nplua polishing, iav polishing)

Polished lub plawv-dimensional ntshiab titanium daim iav titanium chopsticks

1: Rough polishing: Siv lub log tshwj xeeb hemp lossis wool log rau titanium alloy thiab ntxiv tshwj xeeb titanium wax rau polish kom ua tiav qhov chaw du ntawm cov khoom. Them mloog mus rau qhov siv ntawm polishing thiab cov kev taw qhia ntawm cov khoom polishing.

2: Nruab nrab polishing: Siv lub log ntxhib polishing los yog cov ntaub plaub zoo tshwj xeeb uas tsim los rau titanium alloy thiab tshwj xeeb nruab nrab polishing ciab rau titanium alloy los txhuam kom tshem tawm cov kab uas tshuav los ntawm kev ntxhib polishing thiab ua rau saum npoo ntawm cov khoom ci.

3: Zoo polishing: Siv cov paj rwb ntaub log tshwj xeeb uas tsim rau titanium alloy thiab zoo polishing ciab tshwj xeeb uas tsim rau titanium alloy kom cov khoom titanium alloy ncav cuag siab brightness. Kuj tseem muaj qee cov ntaub ntawv me me ntawm qhov chaw ntawm cov khoom.

4: Daim iav Polishing: Siv cov xoob xoob bleached paj rwb ntaub log tshwj xeeb uas tsim los rau titanium alloy thiab tshwj xeeb daim iav wax polished rau titanium alloy kom tshem tawm cov ntaub me ntsis ntawm cov khoom, kom cov titanium alloy yuav muaj daim iav tiav.

Tshuaj polishing

Tshuaj polishing ua tiav lub hom phiaj ntawm leveling thiab polishing los ntawm cov tshuaj tiv thaiv redox 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. Nws tsis xav tau cov cuab yeej tshwj xeeb nyuaj thiab yooj yim rau kev khiav lag luam. 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.
