what is vacuum coating?

Vacuum coating processes are a form of physical vapor deposition, referred to in short as PVD. Using innovative processes, we apply metallic or ceramic coating materials to substrates, thus creating extremely thin (nanoscale) protective layers with convincing characteristics.

When it comes to extremely thin coatings, our vacuum technique achieves the best possible results. Our atomically anchored nanoscale coatings emerge from two sophisticated finishing processes: cathodic arc deposition and plasma-enhanced chemical vapor deposition.

cathodic arc deposition

This physical vapor deposition technique involves the vaporization and ionization of metal to subsequently accelerate it onto the workpiece in the electric field. Reactive gases allow for the trouble-free creation of ceramic surface finishes, such as carbide, oxide or nitride.

plasma-Enhanced Chemical Vapor Deposition (PECVD)

Using this technique, gaseous substances can be deposited onto the substrate at temperatures below 200°C. With common chemical vapor deposition methods, reactions will not take place until a temperature of approx. 1,000°C has been reached. PECVD is ideal for extremely hard, diamond-like carbon coatings.

Our processes: cerid® V-TEC and cerid® duplex V-TEC

Backed by almost 60 years of experience in the area of surface coatings, Aalberts surface technologies relies on progressive research and classic processes. We take full advantage of the capabilities of vacuum coatings and offer two central processes: cerid® V-TEC and cerid® duplex V-TEC.

fields of application of vacuum coating

cerid® V-TEC

cerid® V-TEC coatings by Aalberts surface treatment are high-performance multi-layer coatings consisting of titanium aluminum nitride (TiAlN) and titanium carbon nitride (TiCN). Despite low coating thicknesses between 3 and 6 µm, both materials ensure finishes with a high degree of hardness and good tenacity. Consisting of TiCN, the top layer has a low coefficient of friction, thus offering ideal protection against cold welding. These hard coatings are also recommended for the reduction of lubricants.

cerid® V-TEC is a very robust and wear-resistant coating solution which scores in the area of metal forming as well as in other applications. This surface finish also ensures long service lives in the areas of plastics processing, punching tools and machine components.

cerid® duplex V-TEC

When combining plasma nitriding without compound layers with our tried and tested cerid® V-TEC coatings, it is possible to create a particularly strong bond between the coating and the hardened surface. The wear resistance and life expectancy of the surface coating can thus be increased to a significant extent, which becomes particular apparent when it comes to highly stressed tools. Offering innovative custom coating systems and precision manufacturing, we contribute to your success.

properties and fields of use

Covering a wide range of applications, our vacuum coatings can be found in many different sectors. Offering excellent protection against corrosion, our contour-replicating non-stick coatings conform to the standards of the automotive industry. They are applied, for instance, to pistons, connecting rods or valve drives. Our cerid® 5N coating, which is unique in the world, prevents soot deposits in V12 engines. Besides, our biocompatible, allergy-reducing vacuum coatings have been used in the area of medical engineering for more than 20 years. To ensure good healing results, we finish, for example, dental, knee and hip implants.

Depending on the type of process and the individual application-related requirements, our vacuum coatings come with different characteristics:

  • Reduction of allergens
  • Non-stick effect
  • Biocompatibility
  • Protection against cold welding
  • Contour replication
  • Corrosion protection
  • Wear protection

frequently asked questions - vacuum coatings

WHAT ARE PVD COATINGS?

PVD stands for Physical Vapor Deposition. This process creates hard ceramic layers which are only a few µm thick. These coatings are created in a plasma vacuum process.

WHY IS IT THAT VACUUM COATING TECHNIQUES ACHIEVE THE BEST RESULTS WHEN IT COMES TO THIN COATING THICKNESSES?

Thin coatings are true surface finishes which do not require any rework.

WHY DO VACUUM COATINGS PLAY A PARTICULARLY IMPORTANT ROLE IN THE AREA OF MEDICAL TECHNOLOGY?

When it comes to medical devices, vacuum coatings offer advantages like accurate contours and allergy-reducing surfaces. They are applied, for example, to dental, knee and hip implants.

ARE VACUUM COATINGS SUITABLE FOR TOOLS SUBJECT TO HEAVY LOADS?

Highly stressed forming tools and molds used in the areas of metal forming and plastic injection molding as well as all kinds of components are protected against wear, adhesion and corrosion. The tools’ service life is thus increased by factors between 3 and 10.

WHAT ARE THE STRENGTHS OF VACUUM COATING PROCESSES?

Vacuum coating processes create extremely pure and very thin layers. Thanks to these properties, vacuum coatings can also be used in sensitive areas, such as medical technology.
