Xaws xaim hluav taws xob yuav tsum raug rov qab yog tias muaj teeb meem xws li kev sib dhos, kev kub nyhiab, roughness, tsis loj, thiab hardness ua tsis tau raws li qhov yuav tsum tau ua. Cov tshuaj nickel plating txheej tau muab tshem tawm los ntawm txhua yam khoom siv, roj ntsha electrolytic thiab non-electrolytic plating. Cov neeg ua hauj lwm txiav thiab cov twj tawm ntawm cov hlau electrolytic kuj yoojyim, tab sis lawv tsis haum rau cov kev siv rau qhov chaw ua hauj lwm hauv geometry yog qhov nyuaj thiab qhov tseeb qhov tseeb. Cov chemical deplating txoj kev tsis muaj kev cuam tshuam ntawm cov khoom faib tsis sib luag ntawm hluav taws xob, thiab qhov kev lag luam yog qhov yooj yim, thiab nws yog txoj hau kev rau kev tshaj tawm. Hauv kev xaiv ntawm cov khoom siv tshuaj lom neeg, kev xav yuav tsum raug muab rau cov yam xws li kev ua kom tiav, qhov nqi ntawm qhov kev tiv thaiv, kev tiv thaiv ib puag ncig, thiab qhov txhuam ntawm lub hauv paus hlau.
(1) Tshuaj Alkaline cov tshuaj kua xaim xim kua xaum
Alkaline tshuaj lom neeg raug tshem tawm cov tshuaj muaj peev xwm nyob hauv ntau qhov uas lawv muaj cov nitro compounds, thiab lawv siv ntau dua vim tias lawv muaj ntau dua solubility thiab zoo dua tawm cov khoom xaws, kub, thiab lwm yam hlau, tab sis dawb hauv paus. Qhov concentration ntawm tus nickel complexing tus neeg sawv cev yuav tsum tsis txhob siab dhau, txwv tsis pub nws yuav muaj ib daim ntawv pov thawj ntawm qhov hlau ntawm cov hlau. Qhov no yog siv rau electroless nickel plating rau cov pa carbon feem ntau.
Ntawd yog xim dub thiab tom qab ntxuav tas, daim phuam tau muab tshem tawm nrog NaCN kua.
2 Lub xauv yas ntawm lub npoo hlau uas tsis muaj lub plhaub raug tshem tawm nrog rau kev siv tshuaj HNO3.
(3) Electrolesses nickel plating ntawm txhuas thiab aluminium alloy qhov yuav tsum tau muab tshem tawm los ntawm kev siv cov concentrated nitric acid solution (nrog rau qhov uas tsis pub tsawg tshaj 1.42 g / cm3 thiab ib yam ntsiab lus tsis tsawg tshaj 72%).
Cov khoom ua ntej yuav tsum tau qhuav los tiv thaiv kev qhia txog kev ya raws thiab txo qhov concentration ntawm nitric acid, ua rau corrosion ntawm matrix hlau.
