Analyze one by one: the reasons for the blooming and fogging of the chrome-plated layer!
There are many reasons for the blooming or fogging of the chrome layer, most of which are caused by the underplating layer or other external reasons. For example, there is too much saccharin in the nickel plating solution; the linear velocity of the nickel layer is polished; the polished part chrome plating has oil on…
Chrome plating: find the reason why the deep recess of the part cannot be plated with chrome layer, and the brightness is poor and it is easy to burn
The chrome plating ability is poor, and the deep recesses of the parts cannot be plated with chrome There are many reasons for this type of failure, such as the roughness of the blank or the rough bottom plating; the temperature of the bright nickel is too high or the pH value is too high,…
Analysis of chromium plating failure: high plating voltage, no bubbles at the cathode, cracks and hook marks on the plating layer
1 During electroplating, the voltage is high, but there are no bubbles on the cathode Chromium plating During production, sometimes after stopping plating for a period of time, when the power is turned on again, the voltage will be very high, the current will be very small or even no current, and there will be…
