Plaub yam ntawm kev soj ntsuam zoo rau electroplating txheej

Yuav ua li cas los tsim ib tug tivthaiv uas undergoes zoo soj ntsuam tom qab electroplating ua. Kev soj ntsuam zoo ntawm electroplating txheej muaj xws li cov tsos, thickness, adhesion nrog lub hauv paus hlau, ductility, microhardness, brittleness, corrosion kuj, hnav tsis kam, thiab weldability ntawm cov coatings. Txawm hais tias qhov tshwj xeeb kev soj ntsuam cov ntsiab lus sib txawv nyob ntawm qhov thiab txheej, txheej txheej txheej, corrosion kuj, thiab adhesion thiab thickness ntawm substrate hlau ntawm txheej yog cov ntsiab lus uas yuav tsum tau soj ntsuam rau tag nrho cov coatings.
Txoj kev tshuaj xyuas zoo thiab kev soj ntsuam ntawm cov txheej txheem electroplating muaj lawv tus kheej cov qauv hauv lub tebchaws thiab cov qauv thoob ntiaj teb, thiab cov tuam txhab sib txawv kuj muaj cov qauv kev lag luam sib xws.
(1) Cov tsos ntawm txheej
Cov tsos ntawm cov txheej yog ib qho ntawm cov khoom uas yuav tsum tau kuaj xyuas rau ib feem lossis txheej txheej. Feem ntau, cov tsos ntawm cov txheej yog ncaj qha pom nrog lub qhov muag liab qab nyob rau hauv lub teeb ntuj. Nws cov ntsiab lus suav nrog macroscopic uniformity, xim, ci ci, crystallization txheej xwm, thiab macroscopic adhesion ntawm txheej. Feem ntau hais lus, ntxiv rau nws cov xim tshwj xeeb thiab ci ntsa iab, cov txheej yuav tsum zoo ib yam, ua tib zoo, nrog zoo adhesion, tsis muaj pinholes, kab txaij, blistering, tev, burrs, nodules, pitting, scorching, cracking, tev, tev, xim txawv txav los yog plating to. Txawm li cas los xij, rau qhov chaw plated, me me tsis xws luag feem ntau tso cai rau ntawm tus nuv.
(2) Corrosion kuj ntawm coatings
Muaj ob hom kev xeem tseem ceeb rau kev ntsuas qhov kev tiv thaiv corrosion ntawm cov coatings: kev ntsuam xyuas ib puag ncig ntuj thiab kev ntsuam xyuas kev ua kom nrawm nrawm. Cov qub suav nrog cov kev sim ntawm qhov chaw nyob rau hauv ib puag ncig kev ua haujlwm thiab kev ntsuas huab cua nyob rau hauv cov huab cua sib txawv. Hom qauv no tuaj yeem ntsuas qhov kev tiv thaiv corrosion ntawm cov txheej txheem, tab sis qhov tsis zoo yog tias lub voj voog ntev dhau lawm; Cov yav tas muaj xws li nruab nrab ntsev tsuag tshuaj ntsuam, tooj liab acetate accelerated test, corrosion paste test, electrolytic corrosion test, industrial gas corrosion test, damp heat test, thiab lwm yam.
(3) Adhesion ntawm txheej
Muaj ntau txoj hauv kev los ntsuas qhov adhesion ntawm electroplating txheej thiab cov hlau hauv paus, tab sis lawv yog tag nrho cov kev xeem zoo. Cov kev sim ntau yam rau txheej adhesion muaj xws li kev sib txhuam polishing test, tev tawm, xeem cov ntaub ntawv, hla kev xeem, dabtsi yog khoov xeem, thermal vibration test, sib sib zog nqus nqus cov txheej txheem, thiab lwm yam. Thov xa mus rau lub teb chaws tus qauv rau kev siv tshwj xeeb.
(4) Thickness ntawm txheej
Txhawm rau kom ntseeg tau tias qhov ua tau zoo ntawm cov khoom, cov txheej txheem ntawm cov khoom yuav tsum ncav cuag ib qho tuab. Cov txheej txheem uas nquag siv los ntsuas cov txheej tuab muaj xws li kev puas tsuaj thiab tsis muaj kev puas tsuaj. Txoj kev ntsuas kev puas tsuaj muaj xws li anodic dissolution Coulomb method, metallographic method, dissolution weighing method, kua flow method, droplet method, thiab lwm yam; Cov kev ntsuas tsis muaj kev puas tsuaj muaj xws li cov cuab yeej ntsuas cov cuab yeej, txoj kev sib nqus, eddy tam sim no txoj kev X-ray backscatter method, X-ray spectroscopy, thiab lwm yam.
