The DIAFIN®-Nickel and nickel-phosphorus-based dispersion layers are characterized by the fact that they have several important properties or that the properties can be adapted to the application requirements depending on the composition and/or heat treatment. This can be illustrated using a network diagram for qualitative evaluation, on the basis of which the user can select the required properties.

APPLICATIONS
Tools for the mechanical processing of metallic and non-metallic substrates must have good resistance to friction and wear, combined with a certain degree of corrosion resistance to various environmental influences. Nickel and nickel alloys in particular meet these challenges to a high degree.
The coating system DIAFIN® ist die Lösung zur Erzeugung von Oberflächen auf Werkzeugen für die Zerspanung und das Finishen von Werkstoffen. Depending on the surface requirements, the DIAFIN®-coating is based on a chemical or galvanic nickel-phosphorus alloy or galvanic nickel.
The hardness and, above all, the friction and wear properties can be adapted to a wide range of applications by incorporating dispersion materials or heat treatment.
The hardness of a DIAFIN®-coating can be adjusted to values between around 550 HV and 1,100 HV when using electroless nickel-phosphorus, depending on the phosphorus content and post-treatment. Cubic boron nitride (cBN) or diamond are mainly used as embedded particles for the DIAFIN®-dispersion layers.
Typical applications for DIAFIN® coatings are:
> Honing or dressing tools for measuring gauges for threads or fits, limit plug gauges
> Drills, reaming or honing tools
> Tools for sanding, finishing and superfinishing
> Tapes for sanding or peeling.
DIAFIN® coatings are suitable for further conditioning. The application of an additional DIASHIELD® layer with a thickness of between 3 μm and 20 μm reduces the surface roughness and optimizes the running-in behaviour.

CHARACTERISTIC VALUES FOR DIAFIN LAYERS:
In the case of a DIAFIN® dispersion layer, the thickness of the nickel layer is selected so that the particles (e.g. cBN and diamond) are reliably and homogeneously incorporated into the layer.
The required layer thicknesses are listed in the following table.
Functional properties | Friction-enhancing diamond coating DIAFIN® |
Designation | DIAFIN® | DIAFIN® | DIAFIN® |
Average particle size | 2-10 μm | 11-250 μm | 250-500 μm |
Storage rate | 15 % and 30 % | 15 % and 30 % | 15 % and 30 % |
Layer material | Electroless nickel-phosphorus or electroplated nickel or nickel-phosphorus |
Hardness Layer matrix | 550 – 1.100 HV0,1 |
Layer thickness of the matrix (electroless nickel) | 5 – 50 μm | 11 – 250 μm | 250 – 500 μm |
Layer thickness of the matrix (galvanic nickel) | up to several hundred micrometers |
A characteristic value for the properties of the coating is provided by chemically deposited nickel (if used) with phosphorus contents between 1 % and up to 13 %, available in three state forms:
> Low phosphorus content – 2 % to 5 % / high deposition hardness / lower corrosion resistance
> Medium phosphorus content – 5 % to 10 % / medium deposition hardness / higher corrosion resistance
> High phosphorus content – 10 % to 13 % / lower deposition hardness / high corrosion resistance
The phosphorus content determines the basic hardness of the nickel layer, the maximum hardness that can be achieved using heat treatment and the corrosion resistance.

REQUIREMENTS FOR DIAFIN COATINGS:
The substrate material must be suitable for electroplating in order to achieve very good adhesion of the coating to the substrate. The suitability for electroplating with DIAFIN® must be clarified with the client. In addition, the substrate must have sufficient load-bearing capacity to prevent excessive deformation and the resulting high mechanical stress (in extreme cases up to mechanical destruction) of the coating.
When using a DIAFIN® dispersion coating, the interlocking between the hard materials (e.g. cBN and diamond) of the coating (nickel or nickel-phosphorus) and the surface of the component is determined by the surface hardness of the substrate. A higher surface hardness may make it more difficult to nucleate the substrate surface (i.e. to produce an even and well-adhering nickel dispersion layer). A lower surface hardness increases the shearing (in the form of material wear) of the component material and thus the occurrence of (friction) wear.
