Yuav ua li cas los txiav txim seb lub thickness ntawm ib tug nyuaj chrome plated pas nrig yog uniform

Hla ntu piv txwv ntawm cov tawv chrome plated pas nrig yog ua tiav, thiab ntu ntu ntawm cov tawv chrome plated pas nrig ntawm cov qauv yog hauv av siv cov cuab yeej sib tsoo, los ntawm kev sib tsoo kom zoo, maj mam txo qhov roughness ntawm cov khoom sib tsoo mus rau ua kom cov hlaws dai saum npoo tiaj thiab du. Tom qab ntawd, kev kho polishing yog ua, feem ntau yog siv cov ntaub ntawv xws li pob zeb diamond polishing tus neeg saib xyuas los txhim kho qhov zoo. Cov qauv kho nyuaj chrome plated pas nrig yog muab tso rau hauv lub tshuab ntsuas metallographic rau kev soj ntsuam. Los ntawm kev kho qhov focal ntev thiab kev nthuav dav ntawm lub tshuab tsom iav, ciam teb ntawm chrome txheej thiab substrate, nrog rau kev faib tawm ntawm chrome txheej ntawm hard chrome plated pas nrig ntawm qhov hla ntu tuaj yeem pom meej. Saib seb lub thickness ntawm chrome txheej yog zoo ib yam nyob rau hauv ntau txoj hauj lwm (xws li lub circumferential kev taw qhia thiab cov axial kev taw qhia). Yog hais tias qhov sib txawv thickness yog pom tseeb, nws txhais tau hais tias chrome txheej tsis sib xws.
Hla-section sampling ntawm lub hard chrome plated pas nrig kuj yuav tsum tau, tab sis lub scanning electron microscope muaj ntau dua yuav tsum tau rau cov qauv, yuav tsum tau zoo conductivity thiab nto flatness. Yog li ntawd, kev kho mob xws li tshuaj tsuag kub kuj yuav tsum tau thaum lub sij hawm ua qauv npaj. Cov qauv yog muab tso rau hauv lub tshuab ntsuas hluav taws xob scanning, thiab cov duab daws teeb meem siab ntawm ntu ntu ntawm chrome txheej tuaj yeem tau txais los ntawm kev tshuaj xyuas cov qauv saum npoo nrog lub teeb hluav taws xob. Cov duab no tuaj yeem muab cov ntaub ntawv ntxaws ntxaws microstructural, suav nrog cov qauv siv lead ua, porosity thiab thickness faib ntawm chrome txheej. Siv cov duab tsom xam software, lub thickness ntawm chrome txheej ntawm qhov chaw sib txawv tuaj yeem raug ntsuas kom raug thiab nws qhov sib xws tuaj yeem raug ntsuas kom raug. Qhov sib nqus tuab ntsuas ntsuas lub thickness ntawm chrome txheej raws li lub hauv paus ntsiab lus sib nqus. Thaum lub substrate yog cov khoom sib nqus, qhov kev sojntsuam ntawm qhov sib nqus thickness ntsuas yog muab tso rau ntawm qhov chaw ntawm lub zog chrome plated pas nrig.
Cov cuab yeej txiav txim siab qhov tuab ntawm chrome txheej los ntawm kev ntsuas qhov kev hloov pauv hauv cov hlau nplaum sib nqus ntawm qhov kev sojntsuam thiab cov substrate. Ntsuas ntawm qhov chaw sib txawv ntawm qhov chaw ntawm lub zog chrome plated pas nrig thiab sau cov ntaub ntawv tuab ntawm txhua qhov chaw.
Yog tias cov ntaub ntawv sib txawv ntawm qhov chaw sib txawv me me thiab nyob rau hauv qhov kev tso cai yuam kev ntawm qhov ntsuas, nws txhais tau hais tias lub thickness ntawm chrome txheej yog sib xws; txwv tsis pub, nws qhia tau hais tias lub thickness yog uneven. Qhov kom zoo dua ntawm txoj kev no yog kev sim tsis muaj kev puas tsuaj thiab ceev ceev, tab sis rau nyias chrome txheej los yog tawv chrome daim hlau nrog cov duab nyuaj, qhov ntsuas qhov tseeb yuav raug txwv rau qee yam.
Rau cov tawv chrome daim hlau uas tsis yog sib nqus substrates, eddy tam sim no thickness gauges yuav siv tau. Thaum qhov kev sojntsuam nyob ze rau saum npoo ntawm cov tawv chrome plated pas nrig, qhov ntsuas yuav tsim ib qho chaw sib nqus sib nqus kom tsim cov eddy tam sim no hauv chrome txheej thiab cov substrate. Vim muaj cov yam ntxwv sib txawv ntawm chrome-plated txheej thiab cov substrate, lub thickness ntawm chrome-plated txheej yog txiav txim los ntawm kev kuaj xyuas qhov hloov ntawm eddy tam sim no. Ib yam li ntawd, kev ntsuas tau raug coj los ntawm ntau qhov chaw ntawm lub zog chrome-plated pas nrig, thiab cov ntaub ntawv raug muab piv rau kev txiav txim siab thickness uniformity ntawm chrome-plated txheej. Txoj kev no kuj yog ib qho kev sim uas tsis muaj kev puas tsuaj, thiab cov txheej txheem ntawm lub xeev ntawm chrome-plated txheej yog qhov tsawg, tab sis kev ntsuas qhov tseeb kuj tseem yuav cuam tshuam los ntawm cov khoom xws li conductivity ntawm chrome-plated txheej thiab cov yam ntxwv ntawm cov txheej txheem. cov khoom siv substrate.
Xaiv cov tshuaj reagent tsim nyog uas tuaj yeem xaiv cov txheej txheem chrome-plated yam tsis muaj kev cuam tshuam rau cov khoom siv substrate.
Raus ib feem me me ntawm lub zog chrome-plated pas nrig hauv cov tshuaj reagent thiab nqa tawm cov tshuaj tiv thaiv dissolution nyob rau hauv tej yam kub thiab lub sij hawm tej yam kev mob. Los ntawm kev tswj xyuas lub sijhawm cov tshuaj tiv thaiv thiab cov concentration ntawm cov tshuaj reagent, chrome-plated txheej yuav maj mam yaj. Thaum lub sij hawm dissolution txheej txheem, tshem tawm cov tawv chrome-plated pas nrig ntawm ib ntus, yaug nws nrog dej huv, thiab siv ib tug micrometer los yog lwm yam ntsuas los ntsuas qhov seem thickness ntawm chrome-plated txheej. Txoj kev no tuaj yeem ntsuas qhov kev hloov pauv ntawm cov thickness ntawm chrome-plated txheej ntawm lub sijhawm sib txawv, yog li ntsuas nws cov thickness uniformity. Txawm li cas los xij, txoj kev no yog kev puas tsuaj thiab yuav ua rau qee yam kev puas tsuaj rau lub zog chrome-plated pas nrig, yog li nws feem ntau tsuas yog siv rau cov qauv me me lossis kev kuaj xyuas ntawm cov tawv chrome-plated rods.
Yog hais tias koj xav paub yuav ua li cas los txiav txim seb lub thickness ntawm hard chrome plated rods yog ib yam, koj muaj peev xwm sab laj nrog peb cov neeg ua hauj lwm pab neeg, peb yuav ua hauj lwm rau koj tag nrho 24 teev ib hnub twg!
