Process characteristics
:
Renchang semi-bright medium phosphorus electroless nickel plating has a long cycle life, up to - one cycle (r), [The meaning of cycle is that all nickel is plated out per liter of plating solution The nickel content added to the opening of the cylinder is called a cycle. The minimum plating layer can be deposited in one cycle]
The highest plating speed can reach -
The loading capacity of the plating solution is large, and it can accommodate up to square decimeters per liter. The plating solution works for a long time and has stable performance
Strong deep plating ability and strong throwing ability
High hardness and strong corrosion resistance
Low porosity and no pores in the coating
Good wear resistance , better than electroplated chromium
Good solderability and can be wetted by solder
Good electromagnetic shielding performance, can be used for electronic components and computer hard drives
Performance of electroless nickel plating
Phosphorus Content: -Resistivity:
Density: ./3 Melting point: -℃
Hardness: As plated -() Bonding force: Much higher than after electroplating heat treatment:
Internal stress: Internal stress on steel The stress is lower than
Usage
Renchang semi-bright medium phosphorus electroless nickel plating uses the internationally accepted three solutions, B and B. Open the cylinder with B and analyze the replenishment of working fluid according to the nickel ion concentration. The consumable components can be replenished in and out, which is extremely convenient:
How to open the cylinder
Take the preparation of one liter of working fluid as an example
B
The remaining amount is deionized water (the conductivity is lower than /) and 3. (Adjustment value.)
Temperature: -℃ Loading capacity:
The specific method is to first calculate the volume and draw a scale on the wall in the tank, then fill half of the volume with deionized water, and then Add B and B, use deionized water to add it to a point below the scale line, then use 3. to adjust the value to the scale line, heat it to ℃, and then plating according to the process requirements.
