Yuav ua li cas Electroplating txhim kho cov khoom lag luam tiv taus rau qee qhov teeb meem? Dab tsi cov txheej txheem tuaj yeem txhim kho qhov kev tawm tsam?
Tso lus
Electroplating yog txheej txheem uas tso cov hlau lossis alloy txheej tso rau hauv ib substrate los ntawm electrolysis. Nws yog dav siv los txhim kho cov khoom lag luam xws li corrosion tsis kam, coj kev tawm tsam, kev coj ua, thiab loog. Hauv qee cov ntawv thov, ntsuas qhov tsis kam yog qhov tseem ceeb tshwj xeeb. Piv txwv li, hauv cov khoom siv hauv cov tshuab hluav taws xob, ntu automotive, thiab aerospace, particle adhesion lossis yaig yuav cuam tshuam rau cov khoom ua haujlwm lossis kav dej. Yog li ntawd, txhim kho particle tsis kam los ntawm electroplating tau dhau los ua qhov teeb meem tseem ceeb. Cov hauv qab no yuav tham txog kev nthuav dav yuav ua li cas txhim kho cov khoom lag luam hluav taws xob ua kom zoo, thiab tshaj tawm cov khoom siv hluav taws xob, thiab tshaj tawm- ua.
I. Electring txheej txheem optimization
1. TXHEEJ TXHEEM TXHEEJ TXHEEM
Qhov kev sib txuam ntawm cov txheej txheej ncaj qha cuam tshuam nws cov particle tiv taus. Yog hais tias lub coating tuab yog qhov tsis sib xws, qee thaj chaw yuav yog nyias, ua rau lawv raug mob rau kev yaig lossis hnav. Los ntawm kev ua kom zoo dua electrandating cov txheej txheem electrandating xws li ceev tam sim no, plating lub sijhawm, daws qhov kub, thiab kev sib tw nrawm, tuaj yeem hloov kho. Piv txwv li, cov tshuaj mem tes ua kom zoo dua qub thiab cov kev sib txuam ntawm cov txheej ntawm lub microscale, yog li txhim kho cov ntsiab lus tsis kam.
2. Txhim Kho Txheej Txheej Nthov
Denser txheej txheej, qhov ntau nyuaj nws yog rau cov lus kom nkag mus lossis ua raws li. Kho cov muaj pes tsawg leeg thiab cov tshuaj ntxiv ntawm cov tshuaj electroplating tuaj yeem txhawb nqa cov khoom siv roj fab hauv txheej, li kev txhim kho txheej txheej ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Piv txwv li, ntxiv cov nplej ntxiv (xws li qee cov orginic additives) rau cov tshuab hluav taws xob tuaj yeem txo cov txheej dav dav thiab txhim kho nws cov particle tiv thaiv.
3. Multilayer Txheej tsim qauv
Lub particle resistance ntawm ib txheej txheej txheej yog tsawg, tab sis muaj ntau cov txheej txheem sib zog tuaj yeem txhim kho cov kev ua tau zoo ntawm cov txheej txheem sib txawv ntawm cov khaubncaws sab nraud. Piv txwv li, ib txheej txheej nrog siab adhesion thiab corrosion tsis kam (xws li cov kab tsib) tuaj yeem xaiv, thaum lub zog sab nraud thiab hnav tsis muaj zog (xws li chromium) tuaj yeem xaiv. Tus qauv multilayer no zoo thaiv cov kev tawm tsam thiab txuas ntxiv cov khoom lag luam.
Ii. Txheej Cov Khoom Xaiv
1. Siab - hardness txheej khoom
High - Cov txheej txheej tawv tawv zoo ua rau muaj kev tiv thaiv thiab khawb ntawm cov khoom. Piv txwv li, tawv chrome plating, vim nws lub siab tawv thiab hnav tsis kam, yog siv dav hauv cov ntawv thov tiv thaiv. Tsis tas li ntawd, Nickel - phosphorus alloy txheej ntau kuj muaj qhov siab tawv, thiab lawv cov coj tsis kam tuaj yeem txhim kho kev kho cua sov.
2. Corrosion - Tsis muaj cov ntaub ntawv tiv thaiv
Nyob rau qee qhov chaw ib puag ncig, cov teeb meem cuam tshuam nrog corrosive tawm, nrawm cov khoom puas tsuaj. Yog li ntawd, xaiv cov khoom siv txheej txheej nrog cov siab corrosion siab (xws li npib tsib xee lossis zinc {{}}} {} {txhim kho cov khoom lag luam tiv thaiv. Piv txwv li, zinc - nickel alloy txheej tab sis kuj muaj kev ntseeg siab zoo nyob rau hauv particle cuam tshuam.
3. Cov ntaub ntawv txheej ua haujlwm
Qee yam khoom siv txheej ua haujlwm tuaj yeem txhim kho cov ntsiab lus tiv thaiv los ntawm lawv cov khoom tau txais. Piv txwv li, Polytetrarafluoroethylene (PTFE) sib xyaw muaj cov coefficient ntawm kev sib txhuam thiab tus kheej {1} roj ci thiab hnav. Tsis tas li ntawd, graphene - txhim kho lawv lub zog siab thiab hnav tsis kam, tau dhau los ua lub xov tooj kev tshawb fawb rau particle {}} Resistant txheej.
III. Post - Kev Ua Txheej Txheem
1. Nto Passivation
Deg passivation cov foos ib qho ntom xim oxide zaj duab xis nyob rau txheej txheej, ntxiv txhim kho nws cov particle tiv taus. Piv txwv li, passivation kev kho ntawm stainless hlau txheej tuaj yeem txhim kho lawv corrosion tsis kam thiab partalle tiv taus. Hla dhau los kuj txo cov chaw nquag ntawm cov txheej txheej txheej, txo qhov kev nyiam ua kom muaj cov nplaum.
2. Cov txheej txheem sib dhos
Ua ntawv thov cov tsho tiv thaiv kab mob (xws li cov txheej txheem organic lossis tej hub) rau cov hluav taws xob hluav taws xob tuaj yeem txhim kho cov ntsiab lus ntxiv. Piv txwv li, thov cov khaub ncaws - tiv taus polyurethane txheej tuaj yeem tiv thaiv cov txheej ntawm particle erosion. Tsis tas li ntawd, nanocoating thev naus laus zis, vim nws cov adhesion zoo dua thiab hnav tsis kam, kuj tseem hloov tau siv hauv kev tiv thaiv hauv kev tiv thaiv.
3. Cov txheej txheem saum npoo kom zoo
Hloov cov kev ntxhib los mos los yog roughness ntawm txheej txheej deg tuaj yeem cuam tshuam cov khoom nplaum thiab cov kev coj ua kev coj ua. Piv txwv li, micro {{- arc oxidation tuaj yeem tsim cov qauv txheej microating thaum txhim kho txheej txheej hnav tsis kam. Tsis tas li ntawd, kev kho laser laser sab nrauv tuaj yeem tsim tshwj xeeb micro -}}} nanostructures rau ntawm txheej txheej dos particle.
IV. Cov Ntaub Ntawv Thov Cov Ntawv Thov
Siv cov khoom siv hluav taws xob ua piv txwv, cov txheej txheem hauv qab no tuaj yeem siv los txhim kho lawv cov particle:
1. Ua ntej, ib txheej npib tsib xee yog electropated ntawm substrate nto los txhim kho adhesion thiab corrosion tsis kam.
2. Tom qab ntawd, ib qho tawv chromium txheej yog electroplated raws li txheej txheej sab nraud kom txhim kho hardness thiab hnav tsis kam.
3. Cov plated txheej yog tom qab dhau los ua kom muaj cov yeeb yaj kiab tuab olide oxide, txuas ntxiv txhim kho corrosion tsis kam.
4. Nanocoating yog thov kom txo cov nplooj nplaum thiab hnav.
Los ntawm kev thov sib xyaw ua ke ntawm cov txheej txheem no, cov particle tsis kam ntawm cov khoom siv hluav taws xob tuaj yeem ua kom tau zoo, yog li ncua lawv cov nqi kev pab.
V. Cov Ntsiab Lus
Txhim kho cov particle tiv thaiv cov khoom electroplated zoo, suav nrog kev xaiv electroplation, thiab post {{{} kev ua. Los ntawm kev tswj hwm cov kev sib xyaw thiab qhov ceev ntawm cov txheej txheem plated, cov khoom siv tsis zoo, thiab cov khoom lag luam tsis kam, thiab cov khoom lag luam tsis yeem yuav ua tau zoo dua. Hauv kev siv cov tswv yim, cov txheej txheem tsim nyog ua ke yuav tsum tau raug xaiv raws li cov kev xav tau thiab ib puag ncig kev xav tau kom ua tiav cov anti- cov nyhuv pittle.
