Ntau Hom Hlau Plating

Kev plating hlau yog ib qho txheej txheem uas muaj kev tso ib txheej hlau rau ntawm qhov chaw ntawm lwm yam khoom. Qhov no ua rau ntau lub hom phiaj, suav nrog kev txhim kho qhov zoo li cas, txhim kho kev tiv thaiv corrosion, muab kev tiv thaiv hnav, thiab ua kom muaj kev sib txuas lus zoo dua. Muaj ntau hom kev plating hlau sib txawv, txhua tus muaj nws cov kev siv thiab qhov zoo tshwj xeeb. Nov yog qee hom feem ntau:

Kev Siv Hluav Taws Xob: Kev siv hluav taws xob yog txoj kev siv hluav taws xob los ua hlau plating uas siv ntau tshaj plaws. Nws yog kev muab cov khoom uas yuav tsum tau plated (lub substrate) tso rau hauv cov tshuaj uas muaj cov hlau ions ntawm cov khoom plating. Ib qho hluav taws xob ncaj qha raug xa mus rau hauv cov tshuaj, ua rau cov hlau ions lo rau ntawm qhov chaw ntawm lub substrate, tsim cov txheej hlau sib xws thiab lo rau. Kev siv hluav taws xob yog siv rau hauv ntau yam lag luam, suav nrog tsheb, khoom siv hluav taws xob, thiab cov hniav nyiaj hniav kub, rau kev kho kom zoo nkauj thiab kev ua haujlwm.

Kev Siv Hluav Taws Xob Tsis Siv Hluav Taws Xob: Tsis zoo li kev siv hluav taws xob, kev siv hluav taws xob tsis siv hluav taws xob tsis tas yuav muaj hluav taws xob sab nraud. Hloov chaw, kev tshuaj lom neeg ntawm cov tshuaj txo qis thiab cov hlau ions hauv cov kua tso cov hlau rau ntawm lub substrate. Kev siv hluav taws xob tsis siv hluav taws xob paub txog nws lub peev xwm los pleev xim rau cov duab nyuaj thiab cov nplaim tsis conductive. Nws feem ntau siv rau hauv kev tsim cov ntawv luam tawm Circuit Board (PCBs) thiab hauv kev lag luam uas xav tau kev tswj qhov tuab kom meej.

Kev Siv Tshuaj Pleev Xim Rau Hauv: Kev siv tshuaj pleev xim rau hauv yog ib txoj kev yooj yim uas siv los muab cov khoom siv pleev xim rau hauv cov tshuaj uas muaj ntsev hlau. Cov hlau ions hauv cov tshuaj no lo rau ntawm qhov chaw ntawm cov khoom siv, ua ib txheej nyias nyias ntawm cov hlau uas xav tau. Cov txheej txheem no feem ntau siv rau cov ntawv thov me me thiab ua ib kauj ruam ua ntej kho hauv lwm cov txheej txheem pleev xim.

Kev Tso Pa Hauv Lub Tshuab Nqus Tsev (PVD thiab CVD): Kev Tso Pa Hauv Lub Cev (PVD) thiab Kev Tso Pa Hauv Lub Tshuaj (Chemical Vapor Deposition) (CVD) yog cov txheej txheem siv los tso cov zaj duab xis hlau nyias nyias rau ntawm cov khoom siv hauv qhov chaw nqus tsev. PVD cuam tshuam nrog kev ua pa ntawm cov hlau hauv lub tshuab nqus tsev, ua raws li nws cov khoom tso rau ntawm qhov chaw ntawm cov khoom siv. CVD, ntawm qhov tod tes, siv cov tshuaj lom neeg los tsim cov txheej hlau. Cov txheej txheem no siv rau hauv kev lag luam semiconductor, optics, thiab cov txheej kho kom zoo nkauj.

Anodizing: Anodizing yog ib hom kev plating electrochemical tshwj xeeb uas siv rau ntawm txhuas thiab nws cov alloys. Nws cuam tshuam nrog kev tsim cov txheej oxide tswj hwm ntawm qhov chaw ntawm cov hlau. Anodizing muab kev tiv thaiv corrosion zoo dua, txhim kho kev tiv thaiv hnav, thiab tuaj yeem siv rau kev kho kom zoo nkauj.

Kev Galvanization: Kev Galvanization suav nrog kev txheej hlau lossis hlau nrog ib txheej zinc los tiv thaiv kev xeb. Txoj kev siv ntau tshaj plaws yog kev galvanization kub, qhov twg cov substrate raug muab tso rau hauv zinc molten. Galvanization yog siv dav hauv kev tsim kho thiab kev lag luam tsheb.

Tin Plating: Tin plating yog siv los tiv thaiv kev xeb, txhim kho kev sib txuas, thiab muab qhov ci ntsa iab. Nws feem ntau siv rau hauv kev lag luam ntim khoom noj (cov kaus poom) thiab cov khoom siv hluav taws xob.

Kev plating kub: Kev plating kub muab kev tiv thaiv xeb zoo heev, kev ua hluav taws xob zoo, thiab kev zoo nkauj. Nws feem ntau siv rau hauv kev lag luam hluav taws xob, tshwj xeeb tshaj yog rau cov connectors thiab contacts.

Kev Siv Chrome Plating: Chrome plating yog paub txog nws cov khoom zoo nkauj thiab tiv taus xeb. Nws feem ntau siv rau hauv kev lag luam tsheb thiab chav dej.

Txhua hom hlau plating muaj nws cov txiaj ntsig thiab cov kev siv tshwj xeeb, ua rau lawv yog cov txheej txheem tseem ceeb hauv ntau yam lag luam. Kev xaiv txoj kev plating nyob ntawm cov yam ntxwv xav tau ntawm cov khoom tiav thiab cov ntaub ntawv koom nrog.
