Kev cuam tshuam ntawm Cov Txheej Txheem ntawm Nqus Nyiaj Plating Substrate ntawm Masking Ability

Kev cuam tshuam ntawm Cov Txheej Txheem ntawm Nqus Nyiaj Plating Substrate ntawm Masking Ability

Cov tsos ntawm cov khoom siv hauv paus yog ib qho ntawm cov ntsiab lus tseem ceeb uas cuam tshuam rau lub peev xwm npog. Kev xyaum qhia tau hais tias thaum cov hlau yog electro-deposited ntawm cov khoom sib txawv substrate, lub peev xwm npog ntawm tib plating tov yog txawv thiab zoo heev. Piv txwv li, thaum chromic acid tov yog siv rau chrome plating, thaum hlau chrome accumulates ntawm tooj liab, npib tsib xee, tooj dag thiab hlau, cov kev pab them nqi ntawm cov tshuaj plating yuav txo qis sequentially. Qhov no yog vim hais tias thaum cov hlau ions rov qab los thiab sau rau ntawm cov khoom sib txawv matrix, qhov tseem ceeb ntawm lawv cov khoom muaj peev xwm sib txawv heev. Lub peev xwm poob nrog me me overpotential yog qhov zoo dua, thiab tus nqi ntawm nws lub peev xwm poob tuaj yeem ncav cuag txawm tias nyob rau hauv ib feem nrog qis dua tam sim no, yog li nws lub peev xwm npog qhov zoo dua. Kev cuam tshuam ntawm qhov chaw ntawm cov khoom siv matrix ntawm lub peev xwm npog ntsej muag yog qhov nyuaj dua

Kev cuam tshuam ntawm Cov Txheej Txheem ntawm Nqus Nyiaj Plating Substrate ntawm Bonding Force

Cohesive force feem ntau yog hais txog qhov ntsuas thiab qib uas ib qho khoom txuas mus rau lwm qhov. Yog hais tias lub txheej ntog tawm vim yog mechanical quab yuam los yog deformation, los yog cua tshuab los ntawm cov pa, los yog tev tawm los ntawm corrosion, lub txheej tsis muaj kev sib cuag quab yuam. Kev sib cuag quab yuam yog ib qho tseem ceeb Performance index ntawm electro-deposition. Nws muaj kev sib raug zoo heev thiab tseem ceeb nrog cov tsos ntawm cov khoom siv substrate ua ntej electroplating, thiab qhov zoo ntawm kev sib cuag quab yuam cuam tshuam ncaj qha rau qhov zoo ntawm txheej.

Yog hais tias muaj ntau cov roj stains, rusted khoom thiab lwm yam kab mob nyob rau saum npoo ntawm lub hauv paus cov ntaub ntawv, lub electroplating txheej tsis tuaj yeem txuas ncaj qha nrog rau saum npoo ntawm cov khoom siv hauv paus, uas yuav ua rau cov txheej txheem maj mam tev tawm thiab poob, uas kuj yog cov neeg pluag kev sib cuag ntawm cov txheej thiab nto ntawm lub hauv paus khoom. vim li cas. Ntawm qhov tsis sib xws, yog tias qhov saum npoo ntawm cov khoom siv hauv cov khoom siv hluav taws xob tau raug ntxuav kom zoo ua ntej electroplating, cov txheej electroplating yuav ncaj qha hu rau saum npoo ntawm cov khoom siv hauv paus thiab ruaj khov rau nws.
