Surface finishing in
aviation

Lightweight, resilient, certified
Coating solutions for the highest demands

Technical surfaces
for safety above the clouds

In aviation, quality, precision and safety are crucial to every detail. Components must be able to withstand extreme loads, but at the same time must not weigh too much. Surface finishing is more than just protection. It is a functional part of the system. Metalux offers certified processes that have proven themselves in aviation for years.

The requirements for surfaces in aviation are high: corrosion resistance, dimensional accuracy, insulation or conductivity, all while minimising weight. Each coating must also be documented, traceable and standard-compliant.

Surface finishing in aviation

Our processes are certified in accordance with EN 9100 and fulfil the requirements of Nadcap, a globally recognised standard in the aviation industry.

With our in-house laboratory, we ensure seamless monitoring of all quality parameters, from bath analysis to coating testing. This results in surfaces that our customers in the civil and military aviation sector have relied on for years.

Metalux delivers surfaces that fly, safely, easily and tested.

FAQ about surface finishing in aviation

Why is surface finishing so important in aviation?
In aviation, safety, lightweight construction and durability take centre stage. Surface finishes protect components against corrosion, wear and material fatigue without adding weight – and thus make a decisive contribution to the reliability of the overall system.
Which processes are typically used in aviation?

Proven methods are:

  • Chromic acid anodising – ideal for bonded joints and paint structures
  • Hard anodising – for wear-resistant and electrically insulating surfaces
  • Electroless nickel plating – for dimensionally stable, corrosion-protected components
  • Chromating of aluminium – as a conductive conversion layer, also Cr(VI)-free
Are the processes at Metalux certified?
Yes, our processes are certified in accordance with EN 9100 and meet the requirements of the Nadcap programme – internationally recognised for aerospace quality. In addition, all processes are monitored and documented in our in-house laboratory.
What advantages do coated components offer in aircraft construction?
They are lighter, more durable and functionally more reliable. Depending on the process, components become conductive, insulating, particularly abrasion-resistant or resistant to chemical influences such as fuels, de-icing agents or humidity.
Can Metalux also provide support during the development phase?
Yes, we can advise you as early as the design or pre-series phase in order to select the optimum coating at an early stage and integrate it reliably into your product development process.
How is the quality of the coatings ensured?
Through regular testing, modern measurement technology and the documentation of all parameters in our own laboratory – for absolute process reliability and traceability.
