Nickel-plated busbar yog cov khoom sib xyaw ua ke uas tsim los ntawm kev tso cov txheej txheem ntawm cov hlau npib tsib xee rau ntawm nws qhov chaw los ntawm electroplating lossis tshuaj plating txheej txheem uas siv cov khoom siv tooj liab zoo heev ua lub hauv paus. Raws li qhov siab -kev ua tau zoo nto- kho busbar, npib tsib xee- plated busbar ho txhim kho qhov tawv tawv, hnav tsis kam, corrosion kuj thiab siab -kub oxidation kuj thaum khaws cov khoom zoo heev ntawm tooj liab. Piv nrog cov tooj liab liab liab, cov nickel txheej ntawm nickel-plated busbars tuaj yeem cais cov tooj liab matrix ntawm cov pa oxygen, noo noo thiab corrosive media nyob rau hauv ib puag ncig sab nraud, thiab tiv thaiv cov tooj liab los ntawm kev tsim cov cuprous oxide los yog tooj liab sulfide zaj duab xis uas tsis zoo conductivity. Piv nrog cov tin-plated busbars, npib tsib xee{10}}plated busbars tseem tuaj yeem tuav ruaj khov kev tiv thaiv thiab solderability nyob rau hauv siab -kub ib puag ncig (tshaj 150 degree), thaum lub tin-plated txheej yuav soften los yog txawm yaj ntawm qhov kub thiab txias. Cov txheej npib tsib xee kuj muaj cov khoom sib txawv zoo, uas tuaj yeem tiv thaiv cov atoms ntawm tooj liab hauv tooj liab matrix los ntawm diffusing mus rau qhov kev sib txuas sib txuas thiab zam kev tsim cov nkig intermetallic tebchaw hauv siab - daim ntawv thov kub. In multi-layer composite structures or high-density installation scenarios, the surface hardness of nickel-plated busbars (up to 300–500HV) allows them to withstand multiple plugging and tightening without obvious scratches or indentations, which is especially important for systems that require frequent maintenance or replacement of connections. Flat Bar Liab Ntshiab Copper Nickel Plating yog ib daim ntawv ntawm nickel{23}}plated busbar. Nrog nws lub tiaj tiaj tiaj tus ntoo khaub lig- ntu thiab dhau los ntawm - qhov los yog counterbore tsim, nws yog dav siv nyob rau hauv kev sib txuas fais fab thiab faib busbars ntawm ntau yam khoom siv hluav taws xob hluav taws xob.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cov khoom siv ntawm nickel-plated busbars muaj ob ntu: cov khoom siv hauv paus thiab cov khoom siv plating. Qhov sib txuam ntawm ob qho ncaj qha cuam tshuam rau qhov kev ua tau zoo kawg thiab ntev ntev - kev ntseeg siab ntawm cov khoom. Hais txog cov khoom siv hauv paus, feem ntau siv yog siab - purity tooj liab. Cov qib zoo xws li T2 tooj liab (cov ntsiab lus tooj liab Ntau dua lossis sib npaug li 99.9%) thiab C11000 electrolytic tooj liab. Cov tooj liab liab muaj hluav taws xob zoo heev (li 101% IACS), zoo ductility (elongation Ntau dua lossis sib npaug li 30%) thiab ua haujlwm zoo heev, ua kom yooj yim rau kev ua haujlwm theem nrab xws li xuas nrig ntaus, khoov, thiab txiav. Rau cov ntawv thov uas yuav tsum tau muaj zog dua txhua yam, tooj dag (xws li H62, muaj txog 62% tooj liab thiab txog 38% zinc) tuaj yeem siv los ua cov matrix. Lub zog tensile ntawm tooj dag tuaj yeem yog 2-3 npaug ntawm tooj liab, tab sis cov conductivity poob mus txog 28% IACS. Yog li ntawd, nws yog feem ntau haum rau hauv av los yog kev sib txuas cov xwm txheej uas tsis tas yuav muaj kev coj ua zoo tab sis muaj kev ntxhov siab rau cov neeg kho tshuab siab.

 

Rau qhov hnyav- daim ntawv thov rhiab heev, 6061 aluminium alloy kuj tseem siv tau los ua cov substrate thiab tom qab ntawd nickel plated. Txawm li cas los xij, cov txheej txheem txhuas nickel plating yog qhov nyuaj dua thiab yuav tsum tau ua ntej zinc immersion lossis electroless nickel plating ua primer. Nyob rau hauv cov nqe lus ntawm cov ntaub ntawv plating, npib tsib xee plating yog muab faib ua electroless npib tsib xee plating thiab tshuaj nickel plating raws li cov txheej txheem sib txawv. Electroplated npib tsib xee txheej muaj purity siab (nickel cov ntsiab lus Ntau dua los yog sib npaug rau 99.5%), ib tug silvery dawb metallic luster, nplua nplej, thiab cov thickness feem ntau yog tswj nyob rau hauv ntau ntawm 2-10 μm. Lub hardness ntawm electroplated npib tsib xee txheej yog kwv yees li 200-300HV, uas tuaj yeem nce ntxiv mus rau ntau dua 400HV tom qab kev kho cua sov tsim nyog. Electroless npib tsib xee plating txheej yog npib tsib xee-phosphorus alloy (phosphorus ntsiab lus 3%–12%), uas muaj ib tug semi{16}} ci los yog matte tsos thiab ib tug hardness ntau dua (txog 500–600HV). Txij li thaum cov txheej txheem tso tawm tsis cuam tshuam los ntawm kev faib tawm tam sim no, qhov peev xwm ntawm kev ua haujlwm ntawm complex -zoo li tus workpieces (xws li Flat Bar Red Ntshiab tooj liab Nickel Plating nrog qhov sib sib zog nqus los yog tshwj xeeb- cov qauv zoo li tus) yog zoo dua li ntawm electroplated npib tsib xee.

 

Qhov tsis zoo ntawm electroless nickel plating yog tias nws cov conductivity qis dua li ntawm electroplated npib tsib xee. Nyob rau hauv cov nqe lus ntawm kev sib raug zoo quab yuam ntawm cov txheej thiab substrate, tsim nyog npib tsib xee -plated busbars yuav tsum xeem dhau ib tug dabtsi yog khoov xeem: tus qauv yog rov khoov 180℃kom txog thaum nws tawg. Lub txheej ntawm lub pob txha yuav tsum tsis txhob tev los yog tev tawm. Lub thickness ntawm cov txheej yog tsis yog -kev sim ua puas tsuaj siv X-ray fluorescence thickness gauge (XRF), thiab cov thickness sib txawv feem ntau yuav tsum nyob rau hauv ± 20% ntawm tus nqi nominal. Txhawm rau kom ua tau raws li qhov xav tau ntawm kev txhim kho corrosion ntawm cov chaw sib txawv, cov nickel plating txheej yuav tsum dhau qhov Neutral Salt Spray Test (NSS) kom paub tseeb tias qhov chaw ua haujlwm dav dav yuav tsum tsis muaj xeb liab rau 48 teev, thiab thaj chaw marine lossis tshuaj lom neeg yuav tsum tsis muaj xeb liab rau 96-120 teev.
