I. Txheej Txheem Teeb meem
Ntau dhau tam sim no: Ua rau cov ntxhib, granular txheej.
Tsis txaus tam sim no: Tus nqi qis qis, ua rau thaj chaw tsis muaj txheej txheej.
Tsis zoo Anode-Cathode Distance: Anodes uas nyob ze dhau los yog sib nrug heev cuam tshuam rau kev faib tawm tam sim no.
II. Plating Solution Composition Teeb meem
Imbalanced Chromium Anhydride rau Sulfuric Acid Ratio: Qhov piv yuav tsum yog 100: 1. Qhov tsis sib xws yuav ua rau cov txheej tsis sib xws lossis tsaus nti.
Cov ntsiab lus tsis zoo Trivalent Chromium: Cov ntsiab lus tsawg dhau yuav ua rau xim av me ntsis, thaum cov ntsiab lus siab dhau lawm yuav txo qhov kaj.
Impurity Contamination: Hlau, tooj liab, txhuas, thiab lwm yam hlau ions paug cov tshuaj plating, cuam tshuam rau txheej txheej zoo.
III. Cov teeb meem ua ntej
Kev kho deg tsis zoo: Tsis tiav degreasing thiab xeb tshem tawm ua rau tsis zoo txheej adhesion.
Cov teeb meem ntawm substrate: Kev tshem tawm tsis tiav ntawm cov oxide zaj duab xis ntawm cov hlau tsis xeb cuam tshuam rau txheej adhesion.
IV. Cov Teeb Meem Kev Ua Haujlwm
Kev dai tsis zoo: Cov khoom sib tshooj sib tshooj lossis roj stagnation ua rau thaj chaw tsis muaj txheej txheej. Fais fab tuag los yog ntxiv dej txias thaum lub sij hawm txheej txheem: Ua rau txheej txheej txheej.
Tsis txaus preheating: Tsis txaus preheating ntawm lub workpiece cuam tshuam rau txheej uniformity.
V. Cov khoom siv thiab kev tu vaj tse
Cov teeb meem anode: Cov ntaub ntawv tsis zoo ntawm cov hlau lead chromate rau ntawm qhov chaw anode, cuam tshuam rau txheej zoo.
Kev saib xyuas tsis zoo plating: Kev tsis ua haujlwm tsis tu ncua lossis kho cov tshuaj plating muaj pes tsawg leeg ua rau impurity tsub zuj zuj.
