Hauv ntiaj teb kev lag luam, pob zeb diamond tsis yog tsuas yog lub cim ntawm kev nplua nuj thiab kev nplua nuj xwb tab sis kuj yog ib qho tseem ceeb hauv kev tsim cov cuab yeej txiav thiab sib tsoo. Tam sim no, ua tsaug rau cov txheej txheem electroplating pob zeb diamond, nws yooj yim dua thiab ua haujlwm tau zoo dua los siv cov khoom muaj nqis no rau hauv cov cuab yeej. Pob zeb diamond paub txog lawv qhov nyuaj thiab tiv taus khawb, ua rau lawv yog cov khoom muaj nqis hauv kev tsim cov cuab yeej.
Ib txwm muaj, cov chaw tsim khoom yuav tsum tau muab cov pob zeb diamond tso rau hauv cov cuab yeej tes, uas yog ib qho txheej txheem nyuaj thiab kim heev. Txawm li cas los xij, nrog rau kev tshwm sim ntawm cov txheej txheem electroplating pob zeb diamond, cov chaw tsim khoom tau tsimcov cuab yeej pob zeb diamond electroplatedsai thiab yooj yim.
Electroplating yog ib qho txheej txheem uas khi cov hlau nyias nyias rau cov nplaim hluav taws xob. Hauv cov ntaub ntawv ntawm kev tsim cov cuab yeej pob zeb diamond, ib txheej hlau raug siv rau ntawm cov cuab yeej substrate, thiab cov pob zeb diamond me me tom qab ntawd raug electroplated rau ntawm cov hlau. Txoj hauv kev no tsis yog tsuas yog tsim kom muaj kev sib txuas ntawm cov pob zeb diamond me me thiab cov cuab yeej matrix xwb tab sis kuj ua kom muaj kev faib tawm ntawm cov pob zeb diamond thoob plaws hauv cov cuab yeej.
Lub hauv paus ntsiab lus tom qab kev plating pob zeb diamond yog tias thaum cov tshuaj electroplating raug energized nrog cov khoom ua haujlwm, cov pob zeb diamond me me raug tso rau ntawm cov khoom ua ntej plated. Lub zog hluav taws xob tom qab ntawd ua rau cov nickel tawg, tso cov nickel atoms uas tau tso rau ntawm qhov chaw nrog rau cov pob zeb diamond me me. Raws li lub sijhawm, cov pob zeb diamond ntawm qhov chaw maj mam encased, tsim ib lub pob zeb diamond txheej.
Raws li kev faib cov txheej txheem, kev npaj cov cuab yeej pob zeb diamond electroplated yuav tsum tau dhau los ntawm kev ua ntej, ua ntej plated, xuab zeb sab saud, tshem tawm xuab zeb, ua kom tuab, thiab tom qab ua tiav.
Kev ua ua ntej
Kev kho ua ntej yog ib kauj ruam tseem ceeb hauv cov txheej txheem electroplating kom ntseeg tau tias muaj txiaj ntsig zoo tshaj plaws thiab cov khoom zoo. Hauv kev ua hlau plating, ob kauj ruam tseem ceeb ntawm kev kho ua ntej yog kev kho ua ntej substrate thiab kev kho ua ntej pob zeb diamond. Kev kho ua ntej matrix muaj ntau kauj ruam los xyuas kom meej tias lub matrix huv si thiab tsis muaj cov khoom tsis xav tau. Cov txheej txheem suav nrog kev sib tsoo, kev ntxuav caustic, pickling, kev ua kom muaj zog, kev ntxuav, thiab kev ziab. Cov kauj ruam no ua haujlwm ua ke los tshem tawm cov oxides, qaug zog, lossis cov roj ntawm qhov chaw ntawm lub substrate. Qhov no ua kom muaj kev sib npaug ntawm cov txheej nickel thiab txhim kho kev nplaum rau lub substrate. Kev kho ua ntej ntawm cov pob zeb diamond kuj tseem ceeb ib yam li kom tau txais cov txiaj ntsig zoo plating. Yuav kom ua tiav kev kho ua ntej zoo tshaj plaws ntawm cov pob zeb diamond, kev sib xyaw ua ke ntawm kev sib cais sib nqus thiab kev kho acid-base sib xyaw tau txais yuav. Qhov no tshem tawm cov khoom hlau thiab cov khoom sib xyaw ua ke uas tuaj yeem sib xyaw thiab ua rau cov khoom sib nqus tsis muaj zog ntawm cov pob zeb diamond tsis muaj zog. Tib lub sijhawm, roj uas yuav tau sau rau ntawm qhov chaw ntawm cov pob zeb diamond raug tshem tawm, txhim kho lawv cov khoom ntub.
Ua ntej-plated
Kev plating ua ntej yog muab ib txheej nickel yooj yim rau ntawm qhov chaw ntawm lub substrate los ua ib txheej hloov pauv thiab sib txuas nrog lub substrate.
Xuab zeb sab saud
Cov txheej txheem ntawm kev kho cov pob zeb diamond rau ntawm qhov chaw ntawm lub substrate los ntawm kev siv tshuab lossis kev siv lub cev hu ua sanding. Txoj kev sanding yog muab faib ua txoj kev xuab zeb poob thiab txoj kev xuab zeb faus.
Txoj kev thawj zaug tso cai rau kev xuab zeb rau ib sab ntawm lub substrate ib zaug. Txoj kev no zoo heev rau cov khoom uas muaj pob zeb diamond plated rau ib sab. Nws tsuas yog xav tau me ntsis xuab zeb, tsim ib lub regolith nyias, thiab sab saum toj ntawm xuab zeb ua haujlwm tau zoo, ua rau nws zoo tagnrho rau kev tsim khoom loj. Txawm li cas los xij, txoj kev no tsis haum rau cov khoom cylindrical lossis cov khoom tsis sib xws.
Ntawm qhov tod tes, txoj kev xuab zeb faus tuaj yeem xuab ntau qhov chaw hauv ntau qhov kev taw qhia tib lub sijhawm. Cov txheej txheem no zoo dua rau cov khoom cylindrical lossis cov khoom tsis sib xws thiab xav tau ntau cov xuab zeb. Nws kuj ua rau cov regolith tuab thiab muaj qhov ua tau zoo xuab tsawg dua.
Tshem tawm cov xuab zeb
Tom qab ua tiav cov txheej txheem thauj xuab zeb, cov xuab zeb tuaj yeem raug tshem tawm. Tsa lub substrate thiab co me ntsis kom co cov pob zeb diamond uas tsis lo rau ntawm qhov kawg thiab tsis sib sau ua ke los ntawm cov txheej nickel.
Ua kom tuab
Cov txheej txheem ua kom tuab siv cov mis tshuaj plating zoo ib yam li cov txheej txheem ua ntej plating kom ua rau txheej nickel tuab ntxiv. Thaum lub sijhawm ua ntej plating, sanding thiab thickening plating, yuav tsum tau ua tib zoo saib xyuas cov txheej txheem xws li tam sim no, kub thiab pH.
Kev ua tiav tom qab
Muab cov cuab yeej pob zeb diamond electroplated ntub rau hauv cov kua acetone thiab yaug nrog dej distilled. Coj nws tawm, ziab nws, thiab ua kom sov me ntsis kom txhim kho lub zog sib txuas ntawm cov txheej nickel plating thiab cov substrate, thiab tib lub sijhawm ua kom cov txheej nickel plating nyuaj dua.
