Kanigen® electroless nickel with PTFE (NiPtef)
NiPtef is a co-deposition layer of electroless Kanigen® nickel as a substrate and a composite layer of electroless Kanigen® nickel with PTFE. This process gives the treated parts specific and functional characteristics: hard, self-lubricating and hydrophobic.
In the dispersion process of NiPtef layer, PTFE particles with a diameter of 0.2 to 0.3 μm, are incorporated homogeneously into the electroless nickel matrix.
Properties of electroless nickel nickel deposits with PTFE
Low friction coefficient and good wear resistance
By incorporating a dry lubricant, PTFE, combined with hard electroless nickel matrix, electroless nickel with PTFE is an excellent alternative to the problem of wear and friction between two surfaces. With values of order of magnitude of 0.05, PTFE offers a low coefficient of friction.
The wear and friction properties of NiPtef surface layers are determined by the properties of the two coatings :
- hardness by the nickel - phosphorus matrix
- low friction coefficient and self-lubricating effect due to the PTFE particles
The bottom layer of electroless nickel, is applied for corrosion protection. The thickness of this layer is determined depending on the customers’ specifications. The hydrophobic character of the NiPtef plating contributes to the corrosion resistance of the layer as a whole.
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 materials like : silver (Ag), INVAR, 17-4 PH, … .
- dry lubrication,
- reducing the friction coefficient,
- anti-stick layer,
- improvement of wear resistance,
- repel water and dirt,
The strengths of the Kanigen Group
The proportion (V%) of built in PTFE particles in a NiPtef plating is very high: PTFE V% > 20%.
Co-development with the customer and a third party (competence centre)
To be able to penetrate the German OEM market, our client wanted to develop a retractable towbar system. After studying different plating options on the different parts of this innovative towbar system and with the expertise of Sirris (Competence centre in surface treatment) our NiPtef plating was tested with succes !
"Next to the cost of this process, which was a lot higher than the plating usualy used in this kind of systems, the main challenge of the Kanigen team was to quadruple the capacity within the first year, this seen the unexpected success and much higher ramp up of the product. Thanks to the efforts of cost reduction and capacity enhancements we have made, our client was able to supply its clients on time and the project was a success."
Today, Kanigen is again giving technical support to reduce costs even more without compromising on quality, making it possible for our client to open new markets.
