Lub caij nplooj ntoos hlav hlau phaj ntawm ib lub hoobkas yog muaj mob loj heev los ntawm hydrogen tom qab chrome plating, thiab nws yog tawg nrog me ntsis quab yuam. Nws yog Ameslikas muab xav los ua ib qho teeb meem kub kub. Tom qab kev nkag siab ntxiv, nws yog tshwm sim los ntawm kev tshem tawm chromium.
Tom qab tawv chrome plating, tus neeg teb xov tooj tau pom tias chromium txheej thickness ntawm lub workpiece tsis tau raws li cov kev cai ntawm cov kos duab, tshwj xeeb tshaj yog nruab nrab ib feem ntawm lub workpiece. Siv tsis tau cov txheej txheem plating rau cov txheej txheem plating, lawv mus ntxiv chromium tom qab retreating. Vim tias qhov sib txawv ntawm qhov plaub fab ntawm lub qhov workpiece thiab qhov thickness ntawm txheej nyob hauv nruab nrab, qhov nrab ntawm cov khoom ua haujlwm raug tshem tawm vim nyias plating thiab raug tshem tawm sai sai thaum nws raug rho tawm ntawm cov hydrochloric acid . Cov plaub fab yog tuab vim qhov ntxeev tawm thaum chrome plating. Kev khiav tawm tsis huv. Nyob rau tib lub sijhawm, nws tsis pom tias cov kua qaub qoob loo tau ua rau cov kab uas siv chromium txheej uas tau muab tshem tawm, thiab cov chromium txheej nyob rau plaub lub kaum pob zeb ntawm cov khoom ua haujlwm raug tshem tawm. Tom qab kev ntxiv ntawm chromium, ib qho nyuab me me los yog so. Qhov tshwm sim.
Qhov kev tshem tawm ntawm txheej chromium txheej yog tsim rau cov anode nyob rau hauv cov kua alkaline. Qhov tshuaj tiv thaiv anode yog dawb ntawm cov atoms hydrogen thiab tsis ua rau cov hydrogen hauv daim ntawv ua haujlwm kom muaj kev ntxhov siab nyob hauv txoj hlua khi, uas tsis txhob cuam tshuam ntawm kev ntes vim yog hydrogen infiltration.
Rau qhov chaw hydrogen-permeated, kev kho hydrogen yuav tsum tau ua ntej chrome plating, thiab ces chrome plating
