surface quality for energy and power plant technology

In all of our core processes, hard chrome plating, electroless nickel plating and precision grinding, we process plant components for the energy industry. We regenerate wearing parts for hydropower plants, hard chrome plate machine components of gas turbines and grind shafts for wind turbines using the precision cylindrical grinding process. And this is just a small selection of the diverse process solutions in surface technology for the energy sector.


For various operators and maintenance companies of hydropower plants, we coat machine components such as shaft bushings, winding mandrels, spherical valves, drive cylinders, pistons and spindles with hard chrome. In addition to the surface coating of new parts, we also offer the regeneration of worn components. The repair solution of Betz-Chrom is an inexpensive and time-saving alternative to the new acquisition of wear parts. Shrunk bearing seats from turbine rotors or drive cylinders are being regenerated for example.

Gas turbines

We can apply the desired layer thickness partially where the technical use of the machine parts requires it. We use our hard chrome process for example for the inner coating of serrated washers on gas turbines in order to protect them from wear and tear. Furthermore, one of our special strengths is the precision hard chrome plating or excess hard chrome plating of inner bores. In addition to the surface treatment of new parts, we also regenerate repair parts. The Regeneration of machine components is an inexpensive and time-saving alternative to new acquisitions.

Wind power

In all of our core processes we have already worked for wind power plants. The hard chrome and electroless nickel coating processes protect system components from corrosion and wear. In regard to mechanical processing precision cylindrical grinding of machine components is particularly worth mentioning. In our grinding center, we use modern CNC technology to produce the required surface roughness.

Regeneration processing for the energy industry

In the event of signs of wear or damage, our individual surface treatment enables us to offer high-quality repair solutions that can be implemented at short notice. The components are inspected by our quality management department, stripped, ground clean (e.g. if there are signs of wear on pivots), hard chrome-plated and finally ground to the original dimensions. To enable you to make a well-founded decision between a new purchase or repair of the components, you will of course receive an itemized quotation.

Our core processes

Alt Text

Electroless nickel

For hardness, wear resistance and very high corrosion protection with even layer thickness distribution.

Alt Text

Hard chrome

For corrosion protection, tribological properties and a particularly high wear resistance against mechanical stress.

Alt Text

Precision grinding

For dimensional accuracy, roughness depth and bearing ratio depending on the requested surface quality.
