DIAFIN®dispersion coatings based on nickel and nickel-phosphorous stand out for combining several important characteristics, or for making it possible to adapt their characteristics depending on their composition and/or heat treatment to the requirements of specific applications. This can be illustrated by means of a network diagram for qualitative evaluation, on the basis of which the user can select the required properties.
PRODUCT
SYSTEM SHEET
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 DIAFIN® coating system is the solution for creating surfaces on tools for machining and finishing materials. Depending on the surface requirements, the DIAFIN® coating is based on an electroless nickel-phosphorus alloy or electroplated nickel.
The hardness and, above all, the friction and wear properties can be adapted to the respective task within a wide range through the incorporation of dispersion substances or heat treatment. The hardness of a DIAFIN® coating can be adjusted to values between about 550 HV and 1,100 HV when electroless nickel is used, depending on the phosphorus content and post-treatment. Cubic boron nitride (cBN) or diamond are primarily used as the embedded particles in DIAFIN® dispersion coatings. The layers are deposited in thicknesses from about 10 µm to several hundred micrometres. In addition to a good mechanical stability, the coatings are also characterised by a very high resistance to corrosion.
Typical applications for DIAFIN® coatings:
> Extraction or dressing tools for measurement gages for threads or fittings, plug gages
> Drill bits, reamers or honing tools
> Tools for grinding, finishing and super-finishing
> Belts for grinding or extraction.
DIAFIN® coatings are suitable for further conditioning. For example, the application of an additional DIASHIELD® layer in a thickness between 3 µm and 20 µm reduces the surface roughness and optimises the running-in behaviour.
PRODUCT
SYSTEM SHEET
In the case of a DIAFIN® dispersion coating, the thickness of the nickel layer is selected in such a way that the particles (e.g. cBN and diamond) are reliably incorporated homogeneously in the coating.
The required layer thicknesses are listed in the following table.
| Functional properties | Friction-enhancing DIAFIN® diamond coating |
| Designation | DIAFIN® | DIAFIN® | DIAFIN® |
| Average particle size | 2-10 μm | 11-250 μm | 250-500 μm |
| Coating rate | 15 % and 30 % | 15 % and 30 % | 15 % and 30 % |
| Layer material | Electroless nickel-phosphorus or electroplated nickel or nickel-phosphorus. |
| Hardness of coating 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 (electroplated nickel) | up to several hundred microns |
A characteristic value for the properties of the coating is provided by electrolessly deposited nickel (if used) with phosphorus contents between 1 % and up to 13 %, available in three forms:
> Low phosphorous content – 2 % to 5 % / high deposition hardness / low corrosion resistance
> Medium phosphorous content – 5 % to 10 % / medium deposition hardness / high corrosion resistance
> High phosphorous content –10 % to 13 % / low deposition hardness / high corrosion resistance
10 % to 13 % / low deposition hardness / high corrosion resistance

PREREQUISITES FOR DIAFIN COATINGS:
The substrate material must be suitable for electroplating to achieve the 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 seed 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 material of the component and thereby the occurrence of (friction) wear.
