Nickel-plating
Nickel plating is a versatile surface treatment that offers protection against corrosion, wear, and friction. It is applied both as a top coat and as an undercoat for hard chrome, with the aim of increasing the durability and performance of the component. At Plasmajet, we are experts in both electrolytic nickel plating and chemical nickel plating (autocatalytic).
How Does the Process Work?
Electrolytic nickel plating
This process works according to the same principle as hard chrome plating: a nickel layer is deposited on the part by means of electrolysis.
Features:
- Precise control of coating thickness
- Post-processing usually required for dimensional accuracy
- Most commonly used as an undercoat for hard chrome
Chemical nickel plating (nickel-phosphorus alloy)
An autocatalytic process in which nickel is deposited without an external power source. This ensures a completely uniform layer thickness, even on complex shapes.
Features:
- High phosphorus nickel coating: excellent corrosion resistance
- Can be hardened to 850 HV
Ideal for parts with tight tolerances - Can be applied without post-processing
For applications where low friction and water repellency are important, PTFE particles can be used. (Teflon) are embedded in the nickel layer. This creates a surface with self-lubricating properties.
