Chemical processes
Chemical and electrochemical treatments for defined surface properties.

Surface means function.
Hard chrome, Tenifer QPQ, Metcoloy 2 and ceramic coatings complement precision manufacturing with wear and corrosion protection, dimensional build-up and tailored sliding properties.
The final step matters too
A precision component is only complete when its surface suits its purpose.
Functional surfaces face friction, process media, temperature and mechanical loads. Hard chrome can create hard, wear-resistant surfaces. On suitable steels and cast irons, Tenifer QPQ improves wear and corrosion resistance and sliding properties.
Metcoloy 2 provides hard, thermally sprayed build-up coatings for worn functional areas. Depending on the material and structure, ceramic coatings provide high wear resistance. Additional sealing can close pores and protect the coating against liquids and gases.
Treatment follows operating demands
We start with the required component behaviour, not a particular process.
Hard chrome plating
Electroplated hard chrome coatings for high hardness, wear protection, corrosion resistance and restoration of heavily used functional surfaces.
Tenifer QPQ
Salt bath nitrocarburising with post-treatment to improve wear and corrosion resistance and sliding properties in suitable steels and cast irons.
Ceramic coating
Hard, wear-resistant functional coatings, for example Cr2O3, tailored to the material, medium and mating surface.
Metcoloy 2
Thermally sprayed iron-chromium build-up coating for hardness, wear allowance and restoration of heavily used machine parts.
Thermal processes
Thermal and thermochemical treatments to modify surface layer properties.
Sealing and finishing
Pores in thermally sprayed coatings can be sealed and functional surfaces subsequently machined to specification.
Coordinated partner processes
Specialist processes are coordinated through long-standing partners and planned as part of the overall manufacturing solution.
Starting with the objective
Protect, harden and support service life.
Surface treatment is integrated into the manufacturing solution. Base material, dimensional requirements, coating structure, sealing and final machining remain coordinated.
Corrosion protection and sliding performanceTenifer QPQ or another matched system suited to the material and application
Hardness and dimensional build-upHard chrome or Metcoloy 2 for heavily loaded functional surfaces and targeted restoration
Wear protectionCeramic functional coatings for areas subject to abrasion and sliding wear

Function you can see.
What demands must your component withstand?
Enquire about surface treatments Let’s define its surface through its function.
Tell us the material, medium, mating surface and required properties. We will assess whether hard chrome, Tenifer QPQ, Metcoloy 2, ceramics, sealing or another coating system makes sense.
