Coatings in the Aerospace Industry
- Perfectly Prepared for Takeoff

Qualified and certified: For decades, the aerospace industry has relied on the sophisticated and highly developed coating processes implemented by Aalberts surface treatment. Numerous OEM and customer approvals speak for themselves. Not only is the perfect surface of measur-ably high quality, but it is tailored to your individual needs.

Coatings in the Aerospace Industry- Perfectly Prepared for Takeoff

Corrosion protection in the aviation industry: light, robust and durable

In our search for new technologies, we cooperate closely with our long-standing customers.When doing so, we make use of our expert knowledge and certified methods.Our engineers focus on corrosion protection in the aerospace and defence sectors: Our surface finishes provide components with long-term protection against damages caused by environmental influences.Maintenance and repair costs can thus be reduced to a significant extent.Examples include components for cargo loading systems of passenger and cargo planes.

Together we are strong

Aalberts surface treatment, with its 19 factories, is the surface technology specialist within Aalberts Industries, a global player with 15,000 employees at 150 plants in more than 20 countries. The Aalberts surface treatment Group works closely with aerospace experienced French coating companies DEC and SGi, which also part of Aalberts Industries. All companies see themselves as quality service providers and ensure the highly functional finishing of components and component groups used worldwide by leading manufacturers of aircraft, helicopters, satellites, rockets and space stations.

... 3, 2, 1, Zero – When Every Gram Counts

Satellites, probes and space shuttles must function reliably under the extreme conditions in space.That is why coatings used in the aerospace industry are subject to specific requirements.Apart from that, repairs and the procurement of spare parts are far more complicated in space than on Earth.Failures in the aerospace industry often result in high costs.

  •  As is the case with the construction materials, the coatings used in the aerospace industry must be as lightweight as possible in order to save fuel and allow for reserves.
  • Collisions with small meteorites or asteroids can damage the components, which is why the surface coating must offer extreme impact protection.
  • The coatings' resistance to corrosion has a positive effect on the components' durability, and thus on their economic efficiency.

IVD Aluminium Coating: Efficient against Corrosion

Apart from anodising, hard anodising, plasma coating and varnishing processes, ion-assisted aluminium coatings have become well established in the aerospace industry.

After degreasing and sandblasting, the workpiece is transferred into a chamber for vacuum coating, where its surface is cleaned by means of plasma glow discharge. Immediately afterwards, it is vaporised with electrically charged aluminium powder.The result: efficient corrosion protection at temperatures between 0 and 300°C.

IVD aluminium by Aalberts surface treatment is available in three coating classes:

  • >25 µm for very high corrosion resistance (at least 504 h in the salt spray test)
  • 13 to 25 µm for close tolerances
  • 8 to 13 µm for fasteners and particularly narrow tolerances and/or delicate surfaces

IVD aluminium coatings are applied, for example, to titanium fasteners which are used to join aluminium assembly groups.Aalberts surface treatment implements this specific coating process using drum systems and large coating plants.Thus, we are able to vaporise bulk goods and large components in dimensions of up to 200 x 30 cm.Thanks to movable holders, top-quality surface finishes can also be easily applied to complex parts, such as chassis components, airframe parts or plug connectors

Innovative. Punctual. Responsible.

Together we are strong: more than 1,000 highly qualified specialists, certified and fully documented production processes, modern plant technology, technology development partnership and, not least, on-time delivery (OTD) for optimal production scheduling of our market partners.

  • Light, sturdy and extremely wear-resistant: This base plate from a helicopter was coated with HART-COAT®

  • The IVD aluminium coating was originally developed by McDonnell Douglas as a replacement for the cadmium treatment of steel and titanium components. The IVD aluminium is used primarily for corrosion protection typically in the temperature range from 0 to 300° C. The coating can also serve to prevent bimetallic or galvanic corrosion. One aviation example is the coating of titanium fasteners with IVD aluminium to which aluminium assemblies are connected.
