What are the strong points of this process?

The strong points of the vacuum coating processes is extreme purity and thinness of the layers produced. Among other things, these properties allow use in sensitive areas such as medical technology.

The processes

When the coating to be applied is especially thin, the best results are achieved in the vacuum. We control the chemical reactions and reduce impurities to a minimum. After all, extremely fine coatings can reach their potential only with a high degree of purity. Our atomically anchored nanolayers are based on two advanced vacuum coating processes:

  • Cathodic arc evaporation: Physical vapour deposition (PVD) vapourises metal, ionises it and then hurls it onto the workpiece in an electric field. Reactive gases make it easy to create surfaces such as carbides, oxides or nitrides.
  • Plasma Enhanced Chemical Vapour Deposition (PECVD): This application enables gaseous substances to be deposited on the substrate at less than 200 °C. Unlike conventional chemical vapour deposition, reactions occur at significantly less than 1000 °C. This technology is ideal for extremely hard "diamond-like carbon" coatings.

At Aalberts surface treatment, we capitalise on progressive research and classic processes accumulated over the course of more than 35 years of experience in surface treatment. This is why we not only know which treatment is needed, we can also develop targeted solutions to meet individual needs. Our technical consultants would be happy to tell you more about our proven surface refining applications or to work with you to find an innovation solution.

  • Properties

    The layers produced in the vacuum have different characteristics depending on the type of process:

    • hypoallergenic
    • non-stick property
    • biocompatible
    • protection from cold welding
    • contour-true
    • excellent corrosion protection
    • very high wear protection
  • base material

    PVD:

    • steels with tempering temperatures > 450°C
    • hard metals


    PECVD:

    • steels
    • hard metals
    • Al-, Ti-, Ni- or Cr- base materials
    • non-metallic ceramics
    • glass
    • miscellaneous plastics
  • Application

    We cover a wide range of potential uses. This is why our vacuum coatings are used in so many industries:

    • Non-stick surfaces that follow the natural contour of the workpiece and offer excellent protection from corrosion meet the specifications of the standards applicable to the German automotive industry. They are used for motor components such as pistons, connecting rods and valve trains. Our one-of-a-kind cerid® 5N surface prevents soot residue in 12-cylinder engines.
    • Calibration tools for hollow-chamber profiles in window production are subjected to a high degree of wear and HCl corrosion. Our experts in Lübeck, Germany, have developed a special PVD chrome coating for this purpose - and it has the longest serviceable life of any coating of its kind.
    • The high dimensional stability and the excellent wear and corrosion protection of our nanofine non-stick coatings are a significant factor contributing to long uninterrupted production times in machinery and tool manufacturing.
    • With the development of our cerid® 66NM we have created reliable protection from cold welding. It has significantly increased the serviceable life of tools used to form aluminium and stainless steel.
    • Our biocompatible hypoallergenic vacuum coatings have been in use in the medical field for over 20 years. Our surface treatments, e.g. on dental, knee and hip implants, are conducive to healing.
