Cov cuab yeej pob zeb diamond electroplated muaj ntau yam txheej txheem hauv cov txheej txheem tsim khoom, txhua txoj kev tsis txaus, yuav ua rau lub txheej txheej poob tawm.
Cov nyhuv ntawm kev kho ua ntej plating
Cov txheej txheem kho cov hlau matrix ua ntej nkag mus rau hauv lub tank plating hu ua kev kho ua ntej plating. Kev kho ua ntej plating suav nrog: kev txhuam tshuab, tshem tawm roj, yaig thiab cov kauj ruam ua kom muaj zog. Lub hom phiaj ntawm kev kho ua ntej plating yog tshem tawm cov burr, roj, zaj duab xis oxide, xeb thiab daim tawv nqaij oxidation ntawm qhov chaw ntawm lub matrix, yog li ua rau cov hlau matrix loj hlob tuaj thiab tsim lub zog sib txuas ntawm cov molecular.
Yog tias kev kho ua ntej plating tsis zoo, qhov chaw ntawm lub matrix muaj cov roj zaj duab xis thiab cov oxide zaj duab xis nyias heev, cov hlau ntawm cov hlau matrix tsis tuaj yeem raug nthuav tawm tag nrho, uas yuav cuam tshuam kev tsim ntawm cov hlau txheej thiab cov hlau matrix, uas tsuas yog ib qho kev kho tshuab inlay, lub zog khi tsis zoo. Yog li ntawd, kev kho ua ntej tsis zoo ua ntej plating yog qhov ua rau txheej txheej poob.
Cov nyhuv ntawm plating
Cov mis ntawm cov tshuaj plating cuam tshuam ncaj qha rau hom, qhov nyuaj thiab kev hnav tsis kam ntawm cov hlau txheej. Nrog cov txheej txheem sib txawv, qhov tuab, qhov ceev thiab kev ntxhov siab ntawm cov hlau txheej crystallization kuj tseem tuaj yeem tswj tau.
Rau kev tsim cov cuab yeej electroplating pob zeb diamond, feem ntau cov neeg siv nickel lossis nickel-cobalt alloy. Yog tsis muaj kev cuam tshuam ntawm cov khoom tsis huv plating, cov yam ntxwv cuam tshuam rau kev poob txheej yog:
(1) Qhov cuam tshuam ntawm kev ntxhov siab sab hauv Kev ntxhov siab sab hauv ntawm cov txheej txheem yog tsim tawm hauv cov txheej txheem ntawm electrodeposition, thiab cov khoom ntxiv hauv cov nthwv dej yaj thiab lawv cov khoom lwj thiab hydroxide yuav ua rau muaj kev ntxhov siab sab hauv.
Kev ntxhov siab loj heev tuaj yeem ua rau muaj npuas, tawg thiab poob ntawm lub txheej thaum lub sijhawm khaws cia thiab siv.
Rau nickel plating lossis nickel-cobalt alloy, qhov kev ntxhov siab sab hauv yog txawv heev, qhov siab dua cov chloride cov ntsiab lus, qhov ntau dua qhov kev ntxhov siab sab hauv. Rau cov ntsev tseem ceeb ntawm nickel sulfate txheej kua, qhov kev ntxhov siab sab hauv ntawm watt txheej kua yog tsawg dua li ntawm lwm cov txheej txheej kua. Los ntawm kev ntxiv cov organic luminent lossis kev ntxhov siab tshem tawm tus neeg sawv cev, qhov kev ntxhov siab sab hauv macro ntawm txheej tuaj yeem txo qis thiab qhov kev ntxhov siab sab hauv me me tuaj yeem nce ntxiv.
(2) Qhov cuam tshuam ntawm kev hloov pauv hydrogen hauv txhua qhov kev daws teeb meem plating, tsis hais nws tus nqi PH, yeej ib txwm muaj qee qhov ntawm cov hydrogen ions vim yog kev sib cais ntawm cov dej molecules. Yog li ntawd, nyob rau hauv cov xwm txheej tsim nyog, tsis hais txog plating hauv acidic, neutral, lossis alkaline electrolyte, feem ntau muaj hydrogen precipitation hauv cathode nrog rau cov hlau precipitation. Tom qab hydrogen ions txo qis ntawm cathode, ib feem ntawm hydrogen dim, thiab ib feem seeps rau hauv matrix hlau thiab txheej hauv lub xeev ntawm atomic hydrogen. Nws distort lub lattice, ua rau muaj kev ntxhov siab sab hauv, thiab tseem ua rau txheej deformed tseem ceeb.
Cov teebmeem ntawm cov txheej txheem plating
Yog tias tsis suav nrog cov khoom sib xyaw ntawm cov tshuaj electroplating thiab lwm yam kev tswj hwm cov txheej txheem, qhov tsis ua haujlwm ntawm lub zog hauv cov txheej txheem electroplating yog qhov tseem ceeb ua rau poob txheej. Cov txheej txheem tsim khoom electroplating ntawm cov cuab yeej pob zeb diamond electroplating txawv ntawm lwm hom electroplating. Cov txheej txheem plating ntawm cov cuab yeej pob zeb diamond electroplating suav nrog plating khoob (hauv paus), txheej xuab zeb thiab txheej txheem tuab. Hauv txhua txheej txheem, muaj qhov ua tau tias lub matrix tawm hauv cov tshuaj plating, uas yog, lub zog tawm ntev lossis luv luv. Yog li ntawd, kev siv cov txheej txheem tsim nyog dua, cov txheej txheem kuj tseem tuaj yeem txo qhov tshwm sim ntawm cov txheej txheem shedding.
