Hardware terminal plating have mechanical ability to ascend, anticorrosive, improvement the action such as electrical performance, if the hardware terminal plating color, these functions will not stable and appearance will also greatly.
So what makes a change?
1, the structure shape: hardware terminal compared with strip, its structure is complex, concave and convex place change is big, which can lead to current distribution on the surface of the parts in the electroplating process.
So the current many parts protruding parts distribution, coating is very thick;
Current little sag area distribution, coating is very thin.
So thin coating, thickness is not enough, protection ability, this is hardware terminal concave color first, after the other parts of the cause of the discoloration.
2 and plating solution properties: there are two indicators to measure the performance of the plating solution, a solution is throwing ability, namely the plating solution for uniform coating thickness on the parts distribution;
Another is the depth of the plating solution ability, namely the plating solution in parts deep concave deposit metal coating.
These two kinds of ability is bad, coating is thin, hardware terminal plating would be easy to change color.
3, walking speed, the crystallization of metal ions on hardware terminal process must involve a time factor.
If the same machine, plating solution, process, plating parts for a long time, then the coating thickness, shorter time, thin coating.
The electroplating time actual electroplating speed problem, is refers to the parts go fast time is short, the coating is thin, hardware terminal would be easy to change color, on the other hand, on the other hand.
