Amagnetic electroless nickel (wt%P >10,5)
Amagnetic electroless nickel is a technical layer composed of nickel (Ni) and phosphorus (P: >10,5 wt%). It is applied using the Kanigen ® process (electroless and autocatalytic) by immersion in an aqueous environment.
The phosphor content can be guaranteed with a tolerance of +/- 0,5 wt% P and is measured conform the ISO4527 standard.
This type of deposit is generally used in solenoid applications (valves) and chosen for its electromechanical properties : non-magnetic behaviour, hard and resistant to wear.
The higher the phosphor content, the higher the corrosion resistance. This is why this type of deposit is also used for on-& off-shore , as well for subsea applications. For subsea applications this treatment is often combined with a diffusion heat treatment.
Treated materials The electroless nickel process makes it possible to treat a broad spectrum of metals that are used in industry. The most common that are found at Kanigen Group are: construction steel, alloyed steel, cast iron, stainless steel, aluminium alloys, copper alloys, ...
We also treat more uncommon metals as : silver (Ag), INVAR, 17-4 PH, … .
The strenghts of Kanigen Group
- This deposit is validated by 2 automotive suppliers of VW.
- We are equipped to produce this kind of parts on a fully automated production line in both plants : Genk (B) and Bonneville (F).
- We are also equipped to plate parts requiring a high phosphorous deposit and with large dimensions in our production plant in Genk (B) : the bath dimensions of this production line are 3100 x2200 x2000 mm.
Guarantee a phosphor content >10,5 wt% P
To answer the requirements of our customer, we adapted our Kanigen® formulation to guarantee a phosphor content > 10,5 wt% P, while maintaining a for production interesting (economical) plating deposit rate.
There were 3 challenges in this project :
- enhance the phosphor content to obtain a non-magnetic deposit,
- guarantee the regularity and precision of the deposit on parts mounted on racks (5 000/plating tool) while applying a layer thickness of 60 +/- 3 µm,
- develop feasible and repeatable measurement methods applicable in production. "
The expertise gained during this project in our plant in Genk (B), made it possible to develop another project for another client. This new part is produced at the plant in Bonneville (F) where we meet layer thickness requirements of 80 +/- 2,5 µm.
