Abradable coatings are specially formulated for clearance control applications in gas turbines. By allowing the tips of rotor blades or labyrinth seals to machine a path in the relatively soft but erosion resistant coating deposited in this case, housing or shroud, a close tolerance seal is produced.
The coating applied to the seal rings shown opposite is a plasma sprayed Aluminum-graphite composite for use at 315°-425°C
Abradable coatings are designed to wear preferentially when in contact with another surface in order to reduce rubbing & frictional effects and minimise the damaged experience by the contact surfaces. Abradable coatings are frequently used in rotating applications including aerospace and industrial gas turbines to reduce wear, vibration, noise achieving improved fuel efficiency and reduced exhaust gas temperatures.
