Niaj hnub nimno electrochemistry yog tsim los ntawm Italian chemist Luigi V. Brugnatelli nyob rau hauv 1805. Brugnatelli siv ib tug invention los ntawm nws cov npoj yaig AlessandroVolta tsib xyoos dhau los ua thawj electrodeposition siv electrodes. Tab sis Brugnatelli qhov kev tsim kho tau raug txwv los ntawm Fab Kis Academy ntawm Kev Tshawb Fawb thiab tsis tau siv rau hauv kev lag luam dav dav rau peb caug xyoo tom ntej.

Xyoo 1839, cov kws tshawb fawb Askiv thiab Lavxias tau tsim cov txheej txheem hlau electrodeposition, zoo ib yam li Brugnatelli's invention, rau tooj liab plating ntawm cov ntawv luam tawm. Tsis ntev tom qab ntawd, John Wright ntawm Birmingham, Askiv, pom tias potassium cyanide yog ib qho khoom siv electrolyte rau electroplating kub thiab nyiaj. Xyoo 1840, Wright cov npoj yaig, George Elkington thiab Henry Elkington, tau txais thawj electroplating patent. Lawv nrhiav tau lub Hoobkas electroplating nyob rau hauv Birmingham, thiab cov tshuab tau pib kis thoob ntiaj teb.

Nrog rau kev loj hlob ntawm electrochemical science, nws txoj kev sib raug zoo nrog cov txheej txheem electroplating tau maj mam nkag siab, thiab lwm yam txheej txheem tsis zoo nkauj hlau electroplating tau tsim. Los ntawm xyoo 1850, kev lag luam electroplating ntawm nickel, tooj liab, tin, thiab zinc kuj tau tsim. Raws li ob Elkington invention patents, electroplating tso tsheb hlau luam thiab lwm yam khoom siv tau nthuav dav kom tso cai rau electroplating ntawm ntau yam khoom loj thiab cov khoom tshwj xeeb.

Txoj kev rov ua dua tshiab ntawm electroplated pob zeb diamond laum khoom yog tus cwj pwm los ntawm kev siv ua ntej siv cov cua kub cua txias kev co kos duab kom cais cov txheej abrasive thiab substrate ntawm electroplated pob zeb diamond laum ntsis. Tom qab ntawd, cov txheej txheem abrasive sib cais yog electrolyzed los cais cov pob zeb diamond abrasive hais thiab khi, thiab tau txais pob zeb diamond abrasive hais thiab npib tsib xee hlau los yog npib tsib xee cobalt hlau coatings, ntsig txog; Qhov kom zoo dua yog tias txoj kev rov ua kom sov thiab txias ntawm cov pob zeb diamond laum cov khoom siv, nrog rau kev co duab kos, cais cov substrate los ntawm cov txheej abrasive, tiv thaiv lub substrate los ntawm corrosion los yog electrolysis, tso cai rau nws rov qab siv ntau zaus, thaum tseem tiv thaiv ib puag ncig thiab tib neeg kev noj qab haus huv.
