Peb txhua tus paub tias cov hlau xaum yog mos heev thiab yooj yim tawg. Muaj cov khoom siv zoo li no uas kuj ua los ntawm carbon zoo li cov hlau xaum, tab sis nws yog cov khoom siv nyuaj tshaj plaws hauv ntiaj teb, uas yog pob zeb diamond.
Vim yog qhov tawv thiab tsis muaj ntau ntawm cov pob zeb diamond, tib neeg tau suav tias lawv yog cov pob zeb muaj nqis txij li thaum ub los, thiab cov pob zeb diamond tom qab txiav thiab txhuam hu ua pob zeb diamond, uas yog ib qho ntawm cov pob zeb muaj nqis tshaj plaws hauv ntiaj teb.
Qhov tawv ntawm pob zeb diamond yog siab heev. Nws tuaj yeem kos cov kab ntawm yuav luag txhua yam khoom. Pob zeb diamond yog ntse thiab tsis yooj yim rau cua sov. Yog li nws kuj siv rau hauv cov txheej txheem tsim khoom, xws li kev muab pob zeb diamond rau ntawm ntau yam cuab yeej substrates los ua qee yam cuab yeej sib tsoo thiab txiav. Cov txheej txheem tsim khoom no yog pob zeb diamond electroplated.
Pob zeb diamond electroplated
Pob zeb diamond electroplating yog raws li lub hauv paus ntsiab lus ntawm electroplating. Cov xuab zeb pob zeb diamond yog embedded rau ntawm qhov workpiece nrog nickel. Ib feem ntawm pob zeb diamond yuav raug embedded rau ntawm lub substrate, thiab lwm qhov yuav raug nthuav tawm rau ntawm qhov chaw los tsim ib txheej ua haujlwm ruaj khov thiab hnav-resistant.
Lub hom phiaj ntawm cov pob zeb diamond electroplated yog los ua kom muaj peev xwm txiav thiab sib tsoo los ntawm kev muab cov pob zeb diamond ntom ntom rau ntawm qhov chaw ntawm cov hlau ua haujlwm. Ntau yam cuab yeej sib tsoo uas tsim los ntawm cov thev naus laus zis pob zeb diamond electroplated siv dav hauv tshuab, iav, cov ntaub ntawv tsim kho thiab lwm yam lag luam.
Kev tsim cov pob zeb diamond yuav tsum tau tsim nyob rau hauv ib puag ncig tshwj xeeb, yog li ntawd cov khoom tsim cov pob zeb diamond yog qhov sib xyaw ua ke thiab cov zis yog qhov me me. Pob zeb diamond ntuj tsis tuaj yeem ua tau raws li qhov xav tau, yog li cov pob zeb diamond electroplated yog ua los ntawm cov pob zeb diamond hluavtaws.
Keeb kwm kev loj hlob ntawm kev sib tsoo
Tib neeg muaj keeb kwm ntev ntawm kev siv ntau yam cuab yeej sib tsoo los ua cov khoom. Nyob rau lub sijhawm thaum ub, cov neeg thaum ub siv cov pob zeb ntse, cov pob txha tsiaj, cov pas ntoo thiab lwm yam cuab yeej los yos hav zoov thiab txiav zaub mov, uas kuj yog cov cuab yeej sib tsoo thaum ub.
Muaj ntaub ntawv sau tseg tias nyob rau hauv lub Yuan Dynasty, muaj ib lub cuab yeej hauv Suav teb uas siv roj hmab ntuj los nplaum cov hmoov plhaub rau ntawm daim tawv yaj kom ci. Qhov no yog lub cuab yeej txhuam hniav uas tau sau tseg thaum ub.
Txij li thaum nrhiav pom ntau yam hlau xws li tooj dag, tib neeg tau pib siv lawv cov yam ntxwv tawv dua thiab yas dua los ua cov hlau no rau hauv ntau yam cuab yeej thiab siv dav hauv ntau yam txheej txheem sib tsoo. Txij thaum ntawd los, tib neeg tau nkag mus rau lub sijhawm tshiab ntawm kev siv hlau sib tsoo.
Nyob rau lub caij niaj hnub no, nrog rau kev txhim kho sai ntawm kev tsim khoom lag luam, qhov nyuaj ntawm cov ntaub ntawv ua tiav tau nce siab thiab siab dua, thiab cov cuab yeej sib tsoo hlau ib txwm tsis tuaj yeem ua tau raws li nws cov kev xav tau, yog li tib neeg pib nrhiav cov ntaub ntawv uas muaj qhov nyuaj dua li cov khoom siv abrasives.
Yog li muaj cov khoom sib tsoo xws li cov corundum ntuj, cov silicon carbide dag thiab cov pob zeb diamond dag uas muaj zog dua uas siv dav tam sim no. Tom qab sib tsoo cov khoom no ua cov khoom me me, lawv raug hlawv lossis muab tso rau ntawm lwm cov hlau substrates los ua ib daim duab ntawm cov cuab yeej sib tsoo, yog li ua tiav cov txheej txheem sib tsoo.
Cov yam ntxwv ntawm pob zeb diamond electroplated
Cov khoom ua los ntawm pob zeb diamond electroplated muaj ob ntu: workpiece thiab pob zeb diamond txheej. Yog li ntawd, cov txheej txheem electroplated pob zeb diamond deposition no tuaj yeem tsim ntau yam cuab yeej sib tsoo nrog cov qauv tsis sib xws, me me thiab nyias thiab qhov tseeb siab.
Feem ntau, cov pob zeb diamond electroplated siv nickel ua qhov sib txuas ntawm cov pob zeb diamond thiab cov substrate. Nws yuav muab 1/2 lossis 2/3 ntawm cov pob zeb diamond rau ntawm qhov workpiece, thiab cov txheej yuav tawv heev. Qhov no yuav ua rau cov pob zeb diamond plated tsis yooj yim hnav, thiab cov pob zeb diamond yuav tsis poob yooj yim.
Vim tias qhov nyuaj ntawm pob zeb diamond yog siab heev thiab qhov ntse ntawm cov pob zeb diamond tuaj yeem tswj tau ntev, kev ua haujlwm zoo ntawm ntau yam cuab yeej sib tsoo ua los ntawm pob zeb diamond electroplated kuj tseem yuav siab dua thiab hnav-resistant dua.
Hauv cov txheej txheem tsim khoom ntawm pob zeb diamond electroplated, cov txheej txheem ntawm qhov kub qis tom qab hluav taws xob tau txais yuav, yog li nws yuav tsis tsim qhov kub thiab siab siab rau pob zeb diamond, thiab yuav tsis muaj kev cuam tshuam rau pob zeb diamond nws tus kheej, uas kuj ua kom ntseeg tau tias qhov zoo ntawm pob zeb diamond yuav tsis raug txo qis, thiab zoo dua rau kev txhim kho qhov zoo ntawm kev sib tsoo.
Cov txheej txheem pob zeb diamond electroplating
Pob zeb diamond raw khoom
Xaiv tus lej sib xws ntawm cov pob zeb diamond mesh raws li qhov xav tau ntawm cov cuab yeej pob zeb diamond electroplated, thiab cov pob zeb diamond tsim yuav qhia ib lub polyhedron nrog lub kaum sab xis pob zeb diamond hauv qab lub tshuab microscope, thiab qhia xim daj-ntsuab.
Yuav kom ntseeg tau tias qhov zoo ntawm pob zeb diamond electroplated, tus kws tshaj lij sib nqus separator kuj tseem yuav siv los rho tawm ntau yam tsis huv los ntawm cov pob zeb diamond kom ntseeg tau tias lub pob zeb diamond huv.
Kev tshem roj
Siv cov alkali hauv kev lag luam kom tshem tawm cov roj, muab cov caustic soda rau hauv dej thiab rhaub rau 30 feeb, thiab tom qab ntawd ntxuav nws nrog dej distilled rau 2-3 zaug kom tshem tawm cov roj av ntawm qhov chaw pob zeb diamond.
Cov khoom siv pob zeb diamond electroplated kuj yuav tsum tau degreased. Feem ntau, cov khoom siv workpiece raug muab tso rau hauv lub tshuab ntxuav ultrasonic nrog caustic soda, thiab cov dej raug cua sov kom yaj cov caustic soda, thiab tom qab ntawd kev ntxuav ultrasonic yog nqa tawm rau 30 feeb.
Ua ntej plating
Yuav kom ua rau lub pob zeb diamond thiab lub substrate tuaj yeem sib xyaw ua ke, nws yog qhov tsim nyog los qhwv lub electroplated txheej rau ntawm qhov chaw ntawm lub workpiece ua ntej electroplating lub pob zeb diamond.
Cov electrolyte raug cua sov rau 50 ℃, thiab cov khoom ua haujlwm raug muab tso rau hauv lub dab dej plating uas muaj zog. Tom qab cov hlau nickel thiab cov tshuaj plating ua ke, cov nickel ion yuav tso rau ntawm qhov chaw ntawm cov khoom ua haujlwm, tsim ib txheej plating nyias.
hluav taws xob
Yuav kom muab cov pob zeb diamond tso rau ntawm txheej electroplated ntawm cov khoom ua haujlwm, feem ntau muaj ob txoj hauv kev: txoj kev xuab zeb thiab txoj kev xuab zeb poob. Txoj kev xuab zeb poob tsuas yog ua tiav cov xuab zeb ntawm ib qho chaw ib zaug, yog li nws tsim nyog dua rau cov khoom pob zeb diamond electroplated ib sab; Txoj kev xuab zeb embedding yog embed cov khoom uas xav tau pob zeb diamond electroplated rau hauv cov xuab zeb pob zeb diamond, yog li nws tsim nyog dua rau cov khoom cylindrical lossis cov khoom tsis sib xws.
Txawm li cas los xij, lawv cov hauv paus ntsiab lus zoo ib yam. Tom qab cov tshuaj electroplating thiab cov khoom ua haujlwm raug hluav taws xob, cov pob zeb diamond me me yuav raug muab tso rau ntawm cov khoom ua ntej plated. Nyob rau hauv qhov kev ua ntawm lub zog hluav taws xob, cov nickel yuav lwj thiab tso cov nickel atoms, uas yuav raug tso rau ntawm cov khoom ua haujlwm nrog cov pob zeb diamond me me. Cov pob zeb diamond ntawm qhov chaw yuav maj mam qhwv los ua ib txheej pob zeb diamond.
Ntxuav thiab ziab
Tom qab electroplating, ntxuav cov khoom nrog dej huv, vim tias yuav muaj qee cov kua electroplating thiab pob zeb diamond grit tshuav ntawm cov pob zeb diamond grit; Thaum kawg, cov dej ntawm qhov chaw ntawm cov khoom tuaj yeem ua pa los ntawm cua kub, thiab cov khoom pob zeb diamond electroplated tiav lawm.
