The Aerospace industry is one of the first industries that have completely accepted thermal sprayed coatings. In an aircraft engine, there are hundreds of key components that are supplied with thermal sprayed coatings. Without the use of these thermal sprayed coatings, a turbine will not operate at optimum levels.
A variety of degradation problems exist in aircraft engines as a result of metal to metal wear, fretting, hot corrosion, particle erosion plus others. This degradation is accelerated due to the high-temperature conditions involved. Thermal sprayed coatings impart the required surface condition required to increase the life of certain engine components
Typical thermal sprayed components in the aerospace industry:
- Turbine blades
- Flame tubes
- HPT outer stationary seal
