What do 14.4 million aircraft seats have to do with surface engineering?

👉 In 2025, 9 of the 10 busiest international flight routes were in Asia. Hong Kong–Taipei topped the ranking with around 6.8 million seats offered.

👍 Even more impressive is the Seoul–Jeju route (often described as the Korean equivalent of Mallorca): around 14.4 million seats were offered on this route in 2025.

This makes it one of the busiest flight routes in the world.

This trend also shows how much the demands on modern aviation are changing—in terms of efficiency, weight, wear, and corrosion protection.

Surface properties play an important role in many components.

Depending on the application, Cerakote® offers solutions for a wide range of requirements—from corrosion and wear protection to high-temperature and tribological applications.

It’s not simply a matter of coating a component.

🤝 It’s about matching the material, surface, and coating to the specific application.

This is becoming increasingly important as modern aviation systems grow more capable and complex.
