Hauv kev tsim khoom lag luam, thev naus laus zis thev naus laus zis yog qhov tseem ceeb ntawm kev txhim kho cov khoom siv. Nickel plating, raws li kev siv dav siv electrochemical deg txheej txheem, txhim kho corrosion kuj, hnav tsis kam, thiab zoo li zoo ntawm Nickel Plated Contacts los ntawm kev tso ib zaj duab xis nyias ntawm cov xim hlau nickel rau saum npoo ntawm cov khoom siv substrate. Yog li, dab tsi yog nickel plating? Dab tsi yog nws cov txheej txheem thev naus laus zis thiab kev siv qhov tseem ceeb? Kab lus no yuav piav qhia txog qhov no los ntawm qhov kev xav ntawm cov ntsiab lus ntawm cov khoom siv, kev faib cov txheej txheem, cov yam ntxwv ntawm kev ua haujlwm, thiab kev xaiv thev naus laus zis.
Khoom txhais ntawm Nickel Plating
Nickel plating nws tus kheej tsis yog cov khoom siv, tab sis cov txheej txheem kho saum npoo. Workpieces kho nrog npib tsib xee plating muaj txheej txheej ntawm hlau npib tsib xee. Nickel yog silvery -white ferromagnetic hlau nrog zoo heev tshuaj stability, corrosion kuj, thiab ductility. Raws li tus qauv atmospheric tej yam kev mob, ib tug nyias passivation zaj duab xis yuav tsim nyob rau hauv lub nickel nto, zoo tiv thaiv corrosion los ntawm huab cua, noo noo, thiab tej yam tshuaj lom neeg tawm.
Cov nickel plating txheej feem ntau npog qhov chaw ntawm cov khoom siv hauv paus, uas tuaj yeem yog hlau, tooj liab thiab nws cov alloys, txhuas thiab nws cov alloys, lossis txawm tias qee yam khoom siv yas. Yog li ntawd, thaum peb tham txog "nickel- cov ntaub ntawv plated," peb tau hais txog cov qauv sib xyaw nrog npib tsib xee ua cov khoom siv ua haujlwm. Cov qauv no khaws cov khoom siv hluav taws xob ntawm cov khoom siv hauv paus thaum muab cov nickel txheej txheej nws qhov tshwj xeeb zoo.
II. Main Nickel Plating txheej txheem hom
Electroplating yog cov txheej txheem nickel plating feem ntau. Cov txheej txheem no yog ua nyob rau hauv ib qho electrolyte uas muaj nickel salts, conductive salts, pH buffers, thiab wetting agents, nrog metallic npib tsib xee li anode thiab workpiece li cathode. Raws li kev cuam tshuam ntawm cov hluav taws xob ncaj qha tam sim no, npib tsib xee ions tsiv mus rau qhov chaw cathode, nce electrons, thiab txo qis rau cov nickel atoms, maj mam tso rau hauv cov xim hlau nplaum nickel txheej. Qhov zoo ntawm electroplating yog ceev ceev deposition ceev, siab txheej purity, thiab ib tug dav controllable thickness ntau yam, ua rau nws haum rau loj zus tau tej cov Nickel Txheej Copper Contacts.
Electroless npib tsib xee plating yog nickel plating txoj kev rau Nickel Plated Hluav Taws Xob Cov Hluav Taws Xob uas tsis tas yuav muaj qhov hluav taws xob sab nraud. Nws lub hauv paus ntsiab lus yog siv ib tug txo tus neeg sawv cev ntawm ib tug catalytically active nto los txo cov npib tsib xee ions nyob rau hauv cov tshuaj rau nickel atoms, uas yog ces muab tso rau ntawm lub substrate nto. Vim tias tsis muaj teeb meem ntawm qhov tsis sib xws tam sim no, electroless npib tsib xee plating muaj peev xwm ua tau zoo heev, txawm tias cov khoom siv nrog cov duab nyuaj xws li qhov sib sib zog nqus thiab qhov muag tsis pom, cov txheej txheem tuaj yeem tau txais. Electroless npib tsib xee plating txheej feem ntau yog npib tsib xee-phosphorus alloys lossis npib tsib xee-boron alloys, muaj zog dua thiab hnav zoo dua li electroplated nickel txheej.
Cov yam ntxwv ua tau zoo ntawm Nickel Plating
Zoo heev Corrosion Resistance. Nickel plating nthuav tawm cov khoom zoo passivation rau Nyias Nickel Txheej Hluav Taws Xob Cov Hluav Taws Xob hauv huab cua, tiv thaiv corrosive media los ntawm kev tiv tauj cov khoom siv hauv paus. Cov kev tshawb fawb pom tau hais tias npib tsib xee plating muaj kwv yees li 20% mus rau 25% siab dua corrosion dua li zinc plating. Nickel-plated workpieces qhia kev tiv thaiv txhim khu kev qha nyob rau hauv qhov chaw ntub dej, chaw ua haujlwm, thiab cov xov xwm tsis muaj zog acidic.
Zoo Aesthetic tsos. Nickel plating muaj ib tug silvery - dawb metallic luster. Tom qab polishing lossis passivation ntawm Micro Nickel Plated Contacts, qhov saum npoo yog ci, du, zoo nkauj, huv si, thiab tiv taus xeb. Qhov no ua rau npib tsib xee plating siv dav hauv cov khoom siv teeb pom kev zoo, cov khoom siv kho mob, cov cuab yeej siv, thiab lwm qhov chaw uas zoo li tseem ceeb heev.
High Hardness thiab Hnav Resistance rau Custom Nickel Plated Contacts. Lub microhardness ntawm electroplated npib tsib xee feem ntau yog nruab nrab ntawm HV 160 thiab 300, thaum lub hardness ntawm electroless npib tsib xee plating tuaj yeem ncav cuag HV 500 txog 600, thiab tuaj yeem nce ntxiv mus rau HV 900 tom qab kev kho cua sov tsim nyog. Cov yam ntxwv no tso cai rau npib tsib xee- plated workpieces los tiv thaiv qee qhov kev sib txhuam thiab hnav, ua rau lawv lub neej ua haujlwm ntev.
Zoo solderability thiab hluav taws xob conductivity rau me me nickel plated hu. Nickel plating muaj kev sib raug zoo nrog brazing thiab tsis kam vuam, thaum nws nruab nrab resistivity ua tau raws li qhov xav tau ntawm kev sib txuas hluav taws xob.
Daim ntawv thov ntawm Nickel Plating hauv hluav taws xob tiv tauj
Hauv kev lag luam hluav taws xob thiab hluav taws xob, nickel plating technology tuav txoj haujlwm tsis tuaj yeem hloov. Ntau cov khoom siv hluav taws xob sib txuas, xws li cov khoom siv hluav taws xob, hloov cov neeg sib cuag, thiab cov khoom sib txuas, yuav tsum muaj cov nickel plating txheej ntawm tooj liab lossis tooj liab alloy substrate. Cov Txheej Txheem Txheej Txheem Nickel Plated Contacts no ua raws li qhov sib txawv ntawm qhov sib txawv, tiv thaiv kev sib tshuam - diffusion ntawm tooj liab substrate thiab cov txheej txheej tom ntej plating, thiab tseem muab kev sib cuag ruaj khov.
Los ntawm npib tsib xee plating, Nickel Plated Copper Hloov Cov Tiv Thaiv nto tiv thaiv kev tiv thaiv ntawm cov neeg sib cuag yog tswj tau zoo, thiab oxidation kuj tau txhim kho zoo, yog li ua kom lub sijhawm ntev - kev ntseeg siab ntawm kev sib txuas hluav taws xob. Hauv micro-cov khoom siv hluav taws xob me me, Nyias Nickel Layer Hluav Taws Xob Cov Hluav Taws Xob tuaj yeem txo cov nqi khoom siv thaum tuav cov khoom siv hluav taws xob. Nyob rau hauv hnyav-load scenarios uas yuav tsum tau muaj tam sim no los yog nquag tso / tshem tawm, Hnyav Duty Nickel Plated Contacts, nrog lawv cov thicker plating thiab hnav tsis kam, yog cov kev daws teeb meem.
Kev xaiv thiab tsim cov lus pom zoo
Thaum xaiv cov txheej txheem nickel plating, kev lag luam tawm - yuav tsum tau ua raws li cov ntawv thov tshwj xeeb ntawm Electroless Nickel Plating Rivets. Yog hais tias ib tug loj plating thickness, siab ntau lawm efficiency, thiab tsawg tus nqi yuav tsum tau, electroplating yog ib tug tsim nyog xaiv. Yog hais tias lub workpiece muaj ib tug complex zoo, tsis tshua muaj siab xav tau rau plating uniformity, los yog ib tug siab -hardness, hnav- resistant plating txheej yuav tsum tau, electroless npib tsib xee plating yuav tsum tau muab qhov tseem ceeb. Hauv kev siv hluav taws xob tiv tauj, kev saib xyuas yuav tsum tau them rau qhov porosity, thickness uniformity, thiab compatibility nrog cov txheej txheem vuam tom ntej.
