Polishing yog txheej txheem ntawm kev tshem tawm qhov tsis xws luag thiab qhov tsis sib xws ntawm qhov chaw ntawm titanium alloys los ntawm kev siv tshuab, txhim kho nto smoothness thiab flatness. Lub hom phiaj tseem ceeb ntawm titanium alloy polishing yog txhawm rau txhim kho nws qhov zoo thiab zoo nkauj, thaum tseem txhim kho nws cov corrosion kuj thiab biocompatibility.
Titanium yog ib hom hlau tshiab, thiab nws cov khoom muaj feem xyuam nrog cov ntsiab lus ntawm impurities xws li carbon, nitrogen, hydrogen, thiab oxygen. Cov ntsiab lus impurity ntawm ntshiab titanium iodide tsis tshaj 0.1%, tab sis nws lub zog yog tsawg thiab nws cov plasticity siab. Kev ua tau zoo ntawm 99.5% kev lag luam ntshiab titanium yog raws li nram no: ceev ρ=4.5g/cubic centimeter, melting point 1725 degree, thermal conductivity λ=15.24W/(mK), tensile zog σ b{ {9}}MPa, elongation δ=25%, cross-sectional shrinkage rate ψ=25%, elastic modulus E=1.078 × 105MPa, thiab 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 hnov mob nrog cov cuab yeej abrasive. Ordinary abrasives tsis haum rau kev sib tsoo thiab polishing titanium. Nws raug pom zoo kom siv superhard abrasives nrog zoo thermal conductivity, xws li pob zeb diamond, cubic boron nitride, thiab lwm yam. Lub polishing log ceev feem ntau yog 900-1800 mm/min. Tsis tas li ntawd, titanium nto yog feem ntau sib tsoo kub hnyiab thiab microcracks. Tag nrho cov titanium alloy hniav nyiaj hniav kub, saib pluaj, bracelets, thiab lwm yam titanium alloy cov khoom muaj qee yam teeb meem hauv polishing, yuav tsum tau tshwj xeeb polishing cov ntaub ntawv los polish lub teeb ci.
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. Txawm li cas los xij, thermal conductivity ntawm ntau yam titanium alloys yog li 50% qis dua li ntawm titanium. Lub elastic modulus ntawm titanium alloy yog hais txog ib nrab ntawm cov hlau, yog li nws rigidity tsis zoo thiab nws yog feem ntau deformation. Nws tsis haum rau ua cov pas nrig thiab nyias-walled qhov chaw. Lub springback ntawm machined nto thaum txiav yog loj, li ntawm 2-3 zaus ntawm stainless hlau. Yog li muaj qee qhov teeb meem hauv polishing.
Titanium alloy polishing txheej txheem khiav:
1. Deg pretreatment: Siv cov kua qaub ntxuav, electrolytic polishing thiab lwm txoj kev los tshem tawm cov teeb meem xws li nto xeb thiab oxide txheej, ua rau saum npoo huv si thiab du.
2. Kev Sib Tsoo: Kev sib tsoo tshuab lossis phau ntawv sib tsoo yog siv los tshem tawm cov burrs saum npoo, tsis sib xws, thiab lwm yam tsis xws luag.
3. Polishing: Siv mechanical polishing los yog tshuaj polishing txoj kev los txhim kho qhov smoothness mus rau ib theem.
4. Kev kho Sandblasting: Txau abrasive rau saum npoo kom tshem tawm cov av thiab qhov tsis xws luag.
5. Ntxuav: Ntxuav nrog dej los yog tov kom tshem tawm cov xuab zeb blasting abrasives thiab polishing residues, xyuas kom huv si thiab du nto.
6. Kev kho deg: Raws li cov kev cai sib txawv thiab kev siv, qhov saum npoo yog kho nrog electroplating, anodizing, thiab lwm yam los txhim kho nws cov corrosion kuj thiab cov khoom zoo nkauj.
Mechanical polishing ( ntxhib polishing, nruab nrab polishing, zoo polishing, iav polishing)
Polishing txheej txheem ntshiab titanium daim iav nto titanium chopsticks
1: Rough polishing: polishing nto ntawm cov khoom nrog titanium alloy tshwj xeeb hemp log lossis wool log thiab tshwj xeeb titanium wax. Them mloog mus rau qhov siv ntawm polishing thiab cov kev taw qhia ntawm cov khoom polishing.
2: Nruab nrab polishing: Siv cov titanium alloy tshwj xeeb polishing coarse daim ntaub log los yog cov ntaub plaub zoo nrog titanium alloy tshwj xeeb nruab nrab polishing ciab rau polish, tshem tawm cov qauv sab laug los ntawm ntxhib polishing, thiab ua rau cov khoom nto ci iab.
3: Precision polishing: Siv cov paj rwb ntaub log tshwj xeeb uas tsim los rau titanium alloy thiab precision polishing ciab tshwj xeeb uas tsim los rau titanium alloy kom ua tiav qhov ci ci ntawm titanium alloy khoom. Tseem muaj qee cov qauv ntaub me me rau ntawm qhov chaw ntawm cov khoom.
4: Daim iav polishing: Siv titanium alloy tshwj xeeb bleached paj rwb ntaub log thiab titanium alloy tshwj xeeb daim iav wax polishing kom tshem tawm cov ntaub me ntsis ntawm cov khoom, kom cov titanium alloy daim iav tiav tiav.
tshuaj polishing
Tshuaj polishing yog ua tiav los ntawm oxidation-txo cov tshuaj tiv thaiv ntawm cov hlau hauv cov tshuaj nruab nrab kom ua tiav lub hom phiaj ntawm qib thiab polishing.
Nws qhov zoo yog tias tshuaj polishing yog ywj siab ntawm hardness, polishing cheeb tsam, thiab cov qauv zoo ntawm cov hlau. Ib feem ntawm kev sib cuag nrog cov tshuaj polishing yog polished yam tsis tas yuav tsum muaj cov cuab yeej tshwj xeeb. Nws yog ib qho yooj yim rau kev khiav lag luam thiab yog tsim nyog rau polishing complex structured titanium hniav nyiaj hniav kub txhawb. Txawm li cas los xij, cov txheej txheem tsis zoo ntawm cov tshuaj polishing yog qhov nyuaj rau kev tswj, thiab nws yuav tsum muaj cov nyhuv polishing zoo ntawm cov hniav hniav yam tsis muaj kev cuam tshuam rau lawv qhov tseeb.
Cov txheej txheem polishing ntawm titanium alloy yog cov txheej txheem tseem ceeb, uas yog qhov tseem ceeb rau kev txhim kho qhov zoo thiab zoo nkauj ntawm titanium alloy. Thaum lub sij hawm polishing txheej txheem, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau kev tswj hwm ntawm ntau yam kev tsis sib xws thiab kev txhim kho cov neeg ua haujlwm zoo, tsis tu ncua kev txhim kho qib thiab zoo ntawm polishing tshuab kom tau raws li qhov xav tau ntawm kev lag luam sib txawv thiab thaj chaw rau titanium alloy cov ntaub ntawv.
