Tus nqi ntawm lub tshuab nqus tsev PVD Txheej Rau Hauv Kev Kho Mob

Tus nqi ntawm lub tshuab nqus tsev PVD txheej nyob rau hauv cov ntaub ntawv kho mob

Thov cov PVD coatings rau cov khoom siv kho mob yuav ua tau kom zoo nkauj thiab ua haujlwm zoo. Nov yog qee cov lus teb rau cov lus nug.

Lub cev vapor deposition (PVD) yog lub txheej txheem cov txheej txheem uas muaj ntau tus neeg paub siv los txhim kho kev ua haujlwm ntawm kev txiav cov cuab yeej. Txawm li cas los xij, lub tshuab nqus tsev cov tshuab IKS PVD tuaj yeem muab cathode arc PVD txheej kev pab cuam kom muaj zog thiab ntau lubricating khoom, uas tau nce lub cuab yeej lub neej los ntawm 10 zaug piv nrog cov cuab yeej uncoated, hnav resistant nto.

Tsis tas li ntawd, cov kws kho mob cov khoom siv tau nce siv PVD coatings kom paub qhov txawv ntawm lawv cov khoom siv los ntawm cov khoom zoo sib xws thiab / los txhim kho cov kev ua tau zoo ntawm lawv cov khoom, raws li cov txheej hauv inert yog biocompatible thiab tsis hnov mob nrog cov pob txha, cov nqaij los yog lub cev kua. Piv txwv ntawm cov khoom siv kho mob nrog PVD muaj xws li kev sib tw, kev xyaum siv thiab koob, thiab lwm yam "hnav" rau ntau yam khoom thiab cov ntawv kho hniav .

PVD coatings muab zoo ntug retention, yog li cov cuab yeej phais ntshiab nyob twj ywm. Rau lwm cov khoom siv, lawv txo qhov qis ntawm mating stainless hlau yam thiab pab tiv thaiv oxidation thiab corrosion.

Cov teeb meem uas muaj teeb meem nrog PVD coatings:

Qhov cathode arc PVD txheej txheem yog dab tsi?

Cathode arc PVD yog tus txheej txheem ntawm kev siv lub tshuab siv tshuab arc vaporize ntau yam hlau los ntawm cov khoom tau los hauv cov khoom siv lub tshuab nqus tsev. Cov kab ua pa xws li titanium, chromium, zirconium, aluminium thiab ntau lwm cov kev sib tov nrog cov roj (feem ntau yog nitrogen thiab / los yog cov pa roj carbon uas muaj cov roj cua) tsim ib cov ntaub ntawv uas tso cai rau cov khoom uas muaj coated.

Lub cathode arc PVD ua ib theem siab ntawm cov hlau ionization (tshaj 95%), uas pab kom lub siab txheej lo rau cov khoom siv substrate. Cov qauv feem ntau muaj qhov chaw khiav hauj lwm dav dav, uas ua rau kom muaj kev ruaj ntseg zoo nrog ntau txheej txheem. Lwm cov txheej txheem txheej txheem, xws li kev nplawm los yog xuas plating, tsis tshua muaj zog thiab muaj qhov rais me me, ua rau nws tsis yooj yim rau kev tsim cov khoom zoo zoo.

Dab tsi yuav tsum ua kom tiav ua ntej nrag duab?

Yuav kom tau ib qho zoo nplaum txheej, qhov uas yuav tsum tau co yog qhov tseem ceeb heev rau kev ntxuav. Cov nplaim ntawm ib sab yuav tsum tsis pub dawb ntawm oxides, EDM recasting thiab organic films, vim cov kab mob no tuaj yeem cuam tshuam qhov zoo dua.

Tshem tawm cov kabmob ua ntej txheejtxheem, txheejtxheem cov tuam txhab siv kev ua haujlwm xws li polishing, tumbling, acid etching thiab cov xuab zeb thiab iav hlaws txau. Txawm li cas los xij, ib txhia ntawm cov technologies no yuav hloov qhov chaw tiav ntawm cov coated qhov, ces cov PVD coating tuam txhab feem ntau ua hauj lwm nrog cov neeg siv khoom los tsim cov txheej txheem uas ua tau raws li lawv cov cai kom muaj txheej zoo thiab ib feem zoo li.

Txoj kev txheej txheem puas yuav cuam tshuam rau cov npoo ntse?

Yog hais tias qhov chaw muaj qhov ntse ntug, txoj kev ntxuav tu uas yuav cuam tshuam rau kev pom tseeb ntawm ntug tsis siv. Tsis tas li ntawd, txheej txheem txheej txheem yuav muab kho kom txo tau cov cua sov thiab cov nqi them yog tias qhov txheej txheem me me los yog muaj zog heev. Cov kev txhim kho no ua kom paub tseeb tias cov yeeb yam tsis ntxim nyiam tshaj thiab tias txheej tsis yog tuab heev.

Qhov kev kho mob zoo li cas yog qhov zoo tshaj plaws?

Lub PVD txheej yog nyias nyias (feem ntau yog 0.0001 rau 0.0005 nti) thiab feem ntau rov ua qhov qub ntawm qhov ntu (tshwj tsis yog siv cov txheej txheem tu tsev tu dej). Qhov zoo tshaj plaws kev tshwm sim yog tshwm sim thaum lub qhov saum npoo ntawm qhov yog du. Yog li, cov hniav sib tsoo los yog txhuam hniav feem ntau ua tau zoo dua li cov xuab zeb los yog cov txheej txheem npoo ntom ntom.

Nws yog qhov zoo tshaj plaws rau tus neeg muab daim ntawv tso cai rau tsim ib qho kev ntxhib los mos rau ntawm qhov yog tias qhov xaus ntawm qhov yuav tsum tau siv rau hauv ib cheeb tsam ntawm qhov. Cov khoom textures tej zaum yuav ua paug thaj chaw ntawm qhov no, uas yuav tsum tau ua qee yam ua haujlwm tshiab, cuam tshuam cov nyiaj txuag uas tus neeg muag khoom yuav cia siab tau.

Npaum li cas kub yog siv nyob rau hauv cov txheej txheem PVD txheej txheem?

Txhua hom raug txheej txheem ntawm PVD txheej kub yog li 800 ° F. Cov ntsuas kub yuav hloov qhov nyuaj ntawm qhov chaw los yog ua rau cov khoom ua rau deform (shrink los yog loj hlob). Yuav kom txo tau qhov ua tau zoo, peb npaj siab kom sov cov khoom kub ntawm 900 txog 900 ° F kub thiab txias, ces txheej txheej.

Cov hom ntaub ntawv twg yog siv tau?

PVD txheej yuav siv rau feem ntau ntawm cov hlau kom muaj cua sov rau 800 ° F. Cov ntaub ntawv kho mob uas siv rau ntau tshaj 303,440C thiab 17-4 stainless hlau; Titanium alloy; Thiab qee qhov cuab yeej hlau. PVD coatings yog feem ntau tsis haum rau txhuas vim hais tias txheej txheem txheej txheem yog nyob ze ze ntawm lub pob zeb ntawm cov khoom.

Cov coatings feem ntau yog siv rau kev kho mob li cas?

Cov khoom siv kho mob feem ntau yog IV PVD coatings. Cov feem ntau yog siv cov titanium nitride (TiN) nrog ib tug thickness ntau ntawm 0.0001 rau 0.0002 ntiv, vickers hardness ntau ntawm 2,400 mus 2,600Hv, thiab kub.

Qhov thib ob hom tshuaj kho mob thib ob yog txhuas titanium nitride (AlTiN), feem ntau yog hu ua dub nitride lossis cov titanium dub. Nws muaj ib qhov thickness ntawm 0.0001 rau 0.0002 ntiv tes, qhov muaj zog ntawm 4,000 rau 4,200 Hv, thiab cov dub dub nto.

Lwm ob txoj kev kho mob coatings yog chromium nitride (CrN) thiab Alpha. Lub thickness ntawm CrN yog 0.0001 rau 0.0005 nti, qhov khwv hardness yog 2,200 rau 2,400Hv, thiab kev kho qhov muag nyiaj. Alpha yog txheej multilayer txheej uas muaj ib txheej txheej zirconium nitride (ZrN) thiab tsim nyiaj kub. Nws cov thickness ranges ntawm 0.0001 rau 0.0002 nti, nrog siab tshaj plaws hardness, xws li ntawm 4,400 rau 4,600 Hv. Vim nws qhov kev mob siab tshaj, lubricity thiab hnav ua haujlwm, qhov txheej yuav ua ob txog plaub zaug ntev dua TiN.

Dab tsi yog qhov zoo ntawm PVD tshaj tshuaj lom dej vapor deposition (CVD) txheej txheem?

PVD coatings yog coated ntawm kub dua li CVD coatings, thiab PVD coated qhov tsis tas yuav tsum tau kho cua sov dua tom qab txheej. Tsis tas li ntawd, PVD replicates lub qhov kawg tiav rau sab nraud, thaum lub CVD txheej ua ib qhov tsis muaj qab hau tshwj tsis yog tias qhov feem pua yog polished tom qab txheej.

Dab tsi yog qhov zoo ntawm PVD tshaj anodization?

Coated nrog ib titanium alloy, PVD ntau hnav-resistant dua anodization thiab ua rau nws cov xim zoo dua lub sij hawm.

Ntxiv nrog rau cov khoom siv kho mob thiab cov cuab yeej, cov PVD txheej txheem feem ntau siv los txhim kho cov kev ua tau zoo thiab kev pab cuam lub neej ntawm cov khoom siv thwj, molding cov cuab yeej thiab kev txhaj tshuaj molding hnav.
