Lub luag haujlwm ntawm dej plating ua ntej nqus plating hluav taws xob cua sov raj:

Cov electroplating primer tuaj yeem ua tiav cov hlau zoo nkauj, thiab tseem txhim kho nws cov kev ua tau zoo ntawm cov hluav taws xob, cua sov thiab corrosion kuj, thiab txhim kho nws lub zog txhua yam. Electroplating yuav tsum ua tib zoo xav txog yam xws li cov khoom siv ua haujlwm, cov khoom siv kho tshuab, cov nqi khoom siv, cov nqi electroplating, qhov nyuaj ntawm electroplating, thiab qhov tseeb qhov tseeb.

Qhov kub ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov lub raj muaj dab tsi ntawm PVD lub tshuab nqus tsev electroplating txheej?

1. Kev loj hlob ntawm zaj duab xis nce qhov kub thiab txias, uas muaj txiaj ntsig zoo rau cov qauv thiab cov khoom ntawm cov yeeb yaj kiab. Nitrogen-titanium, nitrogen-titanium thiab lwm yam txheej. Ntawm qhov kub thiab txias ntawm 400-600 degree, hardness zoo dua thiab kev sib khi quab yuam tuaj yeem tau.

2. Qhov kub ntawm cov txheej txheem PVD txheej tsis muaj kev sib raug zoo nrog kev sib raug zoo ntawm kev sib raug zoo, hardness, thiab lwm yam. Thaum lub sij hawm txheej txheej txheej, qhov kub thiab txias tsis txaus, qhov kev loj hlob ntawm zaj duab xis yog tsis txaus, qhov saum npoo yog ntxhib, thiab corrosion kuj thiab microhardness yog txo. . Cov kub kub zoo li tsim coarse columnar crystals. Nws ua rau qhov tsis zoo ntawm cov txheej txheem substrate, qhov txo qis ntawm kev sib khi quab yuam, thiab txo qis ntawm kev ua yeeb yaj kiab.

3. Ua kom lub substrate kub tuaj yeem tshem tawm cov residues volatile thiab txhim kho qhov chaw diffusion thiab recrystallization. Accelerates lub interface cov tshuaj tiv thaiv thiab diffuses lub hauv paus impurities. Substrate melts.

Ua kom qhov loj ntawm cov khoom siv lead ua. Txhawb txoj kev loj hlob ntxiv ntawm recrystallized interface, txo cov kev ntxhov siab sab hauv, nce cov kauj ruam kev pab cuam, nce txheej txheej kub yuav tsum tau cuam tshuam nrog cov substrate, nyob ntawm seb cov qauv metallographic ntawm lub workpiece, kev kho cua sov, geometry, xws li cov npoo ntse, ceev ceev Kev ntsuas kub thiab ntsuas kub. arc tam sim no. Matrix bias thiab cov tshuaj tiv thaiv siab kuj cuam tshuam qhov kub thiab txias. Txheej txheej tuaj yeem pib ntawm 180. Lub workpiece yuav tsum tau coated ntawm qhov kub thiab txias uas yuav tsis ua rau lub cev hloov mus rau cov khoom siv.

4. Qhov kub ntawm PVD txheej tshaj qhov tempering point kom soften lub workpiece.

5. Yog hais tias muaj ob peb qhov nyob rau hauv lub txheej lub tshuab nqus tsev chamber, ntau plasma yuav sib sau ua ke nyob ib ncig ntawm lub workpiece, uas ua rau lub workpiece kub thiab siab deposition tus nqi.
