Stainless steel shrapnel nickel plating layer what problem should note?
To ensure that the product surface quality and performance.
One, the surface film layer must remove, or coating roughness is not easy to light.
Second, the stainless steel plating shall not directly back into nitric acid, and should be electrolytic removal of chromium layer, add fine in dilute nitric acid, is conducive to return when plating coating binding force.
Third, in addition to the oil must be thoroughly, or it will cause poor bonding strength.
Four, preparing nickel plating solution iron ions must not exceed 10 g/L, copper ions must not exceed 1 g/L.
After five, plating nickel electroplating copper, cyanide copper plating not too thick, the sodium cyanide free not too low, current density is not easy to too much, otherwise may cause poor bonding force.
Six, precoated with low PH nickel chloride solution, hydrochloric acid after washing for electroplating nickel.
Stainless steel shrapnel processing nickel plating, pay attention to the above six o 'clock.
To be sure that the product surface quality and performance.
