NIPHOS® Nickel-Phosphorus Electrolyte
NIPHOS® Nickel-Phosphorus Electrolyte
Electrolytic process for the deposition of Nickel-phosphorus
With NIPHOS® nickel-phosphorus alloy layers in barrel-, rack- and reel-to-reel lines can be plated electrolytically. The electrolytes are free from halides and contain, besides nickel, no other heavy metals such as lead or cadmium.
It is possible to work with soluble anodes (nickel), insoluble anodes (platinum-plated titanium or MMO) or a combination of both. The lifetime is almost unlimited and corresponds to the one of bright nickel electrolytes. Nickel-phosphorus layers are amorphous, diamagnetic, abrasion and corrosion resistant. The layers are applied as intermediate layers (prior to e.g. tin, chromium or gold) or as final layer.
Actions
Advantages
- Electrolytic deposition of nickel-phosphorus alloy layers
- Simple electrolyte maintenance at temperatures of 60°C
- Long lifetime of the electrolyte
- Does not contain halides, ammonia or heavy metals such as lead or cadmium
- For rack-, barrel- or reel-to-reel operation
- High hardness (up to 1,200 HV after heat treatment)
- Very good abrasion resistance
- Corrosion resistant
- Suitable as final or intermediate layer
Applications
- Replacement of electroless nickel
- Alternative or addition to technical chromium-plating
- Weldable and bondable surface finish
- Decorative, stainless steel coloured surface finish
- Diamagnetic coating of RF connectors
- Intermediate layer prior to gold-plating of connectors
- Electroforming, e.g. of matrices
