Chrome plated steel tubesyog coated nrog ib txheej ntawm hlau nyob rau saum npoo ntawm cov yeeb nkab steel hlau los ntawm electroplating.Lub hom phiaj tseem ceeb tshaj plaws ntawm chromium plated steel kav yog kev tiv thaiv.Chromium plated steel kav muaj tshuaj ruaj khov thiab tsis hnov mob hauv alkali, sulfides, nitric acid, thiab feem ntau cov organic acids.Chromium plated steel kav tuaj yeem yaj hauv hydrochloride acid (xws li hydrochloride acid) thiab kub sulfuric acid.Qhov thib ob, chromium plating muaj cov cua kub zoo, thiab cov kav dej chromium plated tsuas yog oxidize thiab discolor thaum kub siab tshaj 500 degrees Celsius.Ntxiv mus, nws kev sib txhuam coefficient, tshwj xeeb tshaj yog qhuav txhuam coefficient, yog qhov qis tshaj ntawm tag nrho cov hlau, thiab chrome plated steel kav muaj kev hnav zoo heev.Hauv qhov pom lub teeb pom kev zoo, lub peev xwm rov qab ntawm chromium yog li 65%, nruab nrab ntawm cov nyiaj (88%) thiab npib tsib xee (55%).Chromium tsis hloov xim, thiab chrome plated steel kav tuaj yeem tswj lawv lub peev xwm xav tau ntev ntev thaum siv, uas zoo dua li nyiaj thiab npib tsib xee.Muaj peb hom chrome plated txheej txheem.
1. Kev Tiv Thaiv - Decorative Chromium Plating Protection - Kho kom zoo nkauj Chromium Plating, feem ntau hu ua Decorative Chromium, muaj txheej nyias thiab ci uas feem ntau yog siv los ua txheej txheej ntawm ntau txheej electroplating.Yuav kom ua tiav cov hom phiaj kev tiv thaiv, cov txheej txheem tuab txaus yuav tsum tau ua ntej plated ntawm zinc raws li los yog steel substrate, thiab tom qab ntawd ib txheej ci nruab nrab ntawm 0.25-0.5 yuav tsum tau plated rau saum nws μ Thin txheej chromium ntawm m.Feem ntau siv cov txheej txheem suav nrog Cu / Ni / Cr, Ni / Cu / Ni / Cr, Cu Sn / Cr, thiab lwm yam. Tom qab polishing cov khoom nto nrog cov hniav chromium plating, cov nyiaj xiav iav luster tuaj yeem tau txais.Tsis hloov xim tom qab lub sij hawm raug rau cov cua.Hom txheej no yog siv dav rau kev tiv thaiv thiab kho kom zoo nkauj ntawm cov khoom xws li tsheb, tsheb kauj vab, tshuab xaws, watches, twj paj nruag, thiab khoom siv niaj hnub.Cov polished hniav chromium txheej muaj qhov muaj peev xwm ua kom pom kev zoo rau lub teeb thiab tuaj yeem siv los ua lub teeb pom kev zoo.Plating micro pores lossis microcracks ntawm chromium ntawm ntau txheej npib tsib xee yog ib txoj hauv kev tseem ceeb los txo tag nrho cov tuab ntawm txheej thiab tau txais cov txheej txheem zoo nkauj nrog kev tiv thaiv corrosion siab.Nws tseem yog txoj kev loj hlob ntawm cov txheej txheem electroplating niaj hnub.
2. Nyuaj chromium (hnav-resistant chromium) plating muaj qhov hardness siab heev thiab hnav tsis kam, uas tuaj yeem ua rau lub neej ua haujlwm ntev, xws li cov cuab yeej txiav thiab kos duab, nias thiab casting pwm ntawm ntau yam ntaub ntawv, bearings, shafts, gauges, zog. , thiab lwm yam, thiab tseem tuaj yeem siv los kho qhov ntev ntev ntawm qhov hnav.Lub thickness ntawm hard chromium plating feem ntau yog 5-50 μ m.Nws tseem tuaj yeem txiav txim siab raws li qhov xav tau, qee qhov siab li 200-800 μ M. Hard chromium plating ntawm cov hlau tsis tas yuav tsum muaj txheej txheej nruab nrab.Yog tias muaj cov kev cai tshwj xeeb rau kev tiv thaiv corrosion, sib txawv nruab nrab txheej kuj siv tau.
3. Cov mis nyuj dawb chromium plating txheej yog milky dawb, tsis tshua muaj glossiness, zoo toughness, tsis muaj porosity, thiab xim mos.Nws hardness yog qis dua qhov nyuaj chromium thiab hniav chromium, tab sis nws muaj corrosion kuj siab, yog li nws yog feem ntau siv los ntsuas cov cuab yeej thiab ntsuas vaj huam sib luag.Txhawm rau txhim kho nws cov hardness, ib txheej ntawm cov tawv chromium, tseem hu ua ob txheej chromium txheej, tuaj yeem pleev xim rau saum npoo ntawm cov xim dawb, uas sib txuas cov yam ntxwv ntawm ob lub mis dawb chromium txheej thiab tawv chromium txheej.Nws yog feem ntau siv rau txheej txheej uas yuav tsum tau hnav tsis kam thiab corrosion kuj.
4. Porous chromium plating (porous chromium) siv cov yam ntxwv ntawm cov kab nrib pleb zoo hauv cov txheej chromium nws tus kheej.Tom qab plating nyuaj chromium, txhua yam, tshuaj, los yog electrochemical porosity kev kho mob yog nqa tawm mus ntxiv ntxaum thiab nthuav cov kab nrib pleb.Qhov saum npoo ntawm chromium txheej yog npog nrog dav grooves, uas tsis yog tsuas yog muaj cov yam ntxwv ntawm hnav-resistant chromium, tab sis kuj zoo khaws cov ntaub ntawv lubricating, tiv thaiv kev ua haujlwm tsis yog lubricated, thiab txhim kho kev sib txhuam thiab hnav tsis kam ntawm workpiece nto.Nws yog feem ntau siv rau plating qhov chaw ntawm zawv zawg kev sib txhuam qhov chaw nyob rau hauv lub siab hnyav, xws li lub puab chamber ntawm sab hauv combustion cav cylinder chim, piston nplhaib, thiab lwm yam.
⑤ Plating dub chromium dub chromium txheej muaj cov luster zoo ib yam, kho kom zoo nkauj, thiab zoo ploj mus;Lub hardness kuj yog siab (130-350HV), thiab hnav tsis kam yog 2-3 zaug siab dua li cov xim npib tsib xee nyob rau hauv tib lub thickness;Nws cov corrosion kuj yog tib yam li zoo tib yam chromium plating, feem ntau nyob ntawm lub thickness ntawm nruab nrab txheej.Cov cua kub zoo, tsis muaj xim tsis zoo hauv qab 300 ℃.Cov txheej dub chromium tuaj yeem raug coated ncaj qha rau saum npoo ntawm hlau, tooj liab, npib tsib xee, thiab stainless hlau.Txhawm rau txhim kho corrosion kuj thiab cov nyhuv zoo nkauj, tooj liab, npib tsib xee, lossis tooj liab tin alloy tseem tuaj yeem siv los ua cov txheej hauv qab, thiab cov xim dub chromium tuaj yeem plated ntawm nws qhov chaw.Dub chromium txheej feem ntau yog siv los tiv thaiv thiab kho kom zoo nkauj ntawm qhov chaw ntawm cov cuab yeej aviation thiab cov cuab yeej kho qhov muag, lub hnub ci zog nqus vaj huam sib luag thiab cov khoom siv niaj hnub.
