APPLICATION
As a rule, there are movements between parts of equipment or sliding and friction processes between equipment and the products to be machined in a wide variety of equipment and systems. In the majority of cases, this results in more or less pronounced wear on parts of the equipment. Such wear loads can occur, for example, in equipment for the extraction of raw materials in the petroleum industry, but also in the manufacture of textile products.
To maintain the functionality of equipment and systems, wear on such contact surfaces must be effectively prevented or reduced. Electroless and electroplated nickel and nickel-phosphorus coatings are very suitable as surface protection.
DIAPROTECT®-coatings were specially developed to protect against heavy abrasive and chemical wear.
The hardness of a DIAPROTECT®-coating can be adjusted to values between approx. 500 HV and 1,100 HV depending on the phosphorus content and after-treatment. This means that surfaces can be adapted to the respective type of load, e.g. different frictional stresses or different mechanical loads or chemical resistance. DIAPROTECT® achieves the highest wear resistance primarily through its dispersion coating design, in which diamond is predominantly used as embedded particles. The layers are deposited in thicknesses from about 10 µm to several hundred micrometres.
In addition to the good wear resistance, DIAPROTECT®coatings are also characterised by a very high level of corrosion resistance, whereby excellent durability is achieved for many technical applications.
Typical applications for DIAPROTECT®-coatings:
> Pump bodies and rotors in the chemical industry
> Parts in the textile industry subject to heavy wear
> Components used in crude oil and natural gas delivery and the chemical industry
Optimisation through combination: A combination coating with a thickness of up to 10 μm with DIASHIELD® can be used to reduce surface roughness. This can be attributed to a substrate that is too rough or to the deposition of DIAPROTECT®-coatings with thicknesses significantly greater than 20 µm.
PRODUCT
SYSTEMSHEET
The coatings for increasing wear resistance are available in variants with different compositions, different types of deposition and in combination with dispersion coatings with different types of dispersion materials. The type of coating to be used depends on the load at the place of use and can consist of both wear load and corrosion load.
| Functional properties | Friction-enhancingDIAPROTECT® diamond coating |
| Designation | DIAPROTECT NANO | DIAPROTECT 2D | DIAPROTECT 10D |
| Average particle size | 0,5 μm | 2 μm | 10 μm |
| Coating rate | 15 % and 60 % | 15 % and 60 % | 15 % and 60 % |
| Layer material | Electroless nickel-phosphorus or electroplated nickel or nickel-phosphorus. |
| Hardness of coating matrix | 550 – 1.000 HV0,1 |
| Layer thickness of the matrix (electroless nickel) | 10 – 300 μm | 10 – 300 μm | 10 – 300 μm |
| Layer thickness of the matrix (electroplated nickel) | up to several hundred microns |
The thickness of the nickel layer is chosen so that the particles (e.g. diamond) are homogeneously incorporated into the layer.
Another characteristic value of the coating is provided by the electroless nickel coating (as far as it is used for the coating) with phosphorus contents between 2 % and up to 13 %, available in three state 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
The phosphorous content determines the basic hardness of the nickel layer, the maximum hardness that can be achieved using temperature treatment, and the corrosion resistance.

REQUIREMENTS FOR WEAR-ENHANCING COATINGS
The characteristic of enhancing the wear-resistance of a surface is linked to certain design requirements:
> Suitability for electroplating – the substrate material must be suitable for electroplating, which is primarily reflected by very good adhesion of the coating to the substrate. The suitability for electroplating with DIAPROTECT® must be clarified with the client in advance.
> Sufficient load-bearing capacity of the substrate – the substrate must have sufficient load-bearing capacity to prevent excessive deformation with the associated collapse of the coating.
> Hardness of the surface of the contact surfaces – when using a DIAPROTECT®-dispersion coating, the interlocking between the hard materials (e.g. diamond) of the dispersion coating (usually a nickel or nickel-phosphorus layer) and the surface of the component is determined by the surface hardness of the component. A higher surface hardness makes it more difficult for the diamonds to penetrate the component surface. A lower surface hardness increases the shearing (in the form of material wear) of material of the component due to (friction) wear.
