It has been shown that the surface finish of the airfoils can be satisfactorily restored by using suitable compressor coatings. Recent developments in such coatings have been made to improve upon the ...

Industrial gas turbine (IGT) manufacturers and maintenance, repair, and overhaul (MRO) personnel are continually seeking new ways to improve the performance and longevity of critical components.

Elevated temperatures take a big toll on gas turbine components risking cracks, corrosion, wall thickness, and material condition. Repair enhancements can extend a part’s life by slowing its ...

Thermal barrier coatings can be applied using different processes. They can be wet-sprayed or applied using an air plasma spray gun, as pictured here. Photo courtesy: GE Power & Water The quest for ...

Gas turbines are used for the production of electricity and in aircraft engines. To increase the life-span of the turbines, they are sprayed with a surface coating. The coating consists of two layers ...

Ytterbium silicide (Yb-Si) is a promising coating material for the high-temperature sections of aircraft gas turbine engines. Although Yb-Si is heat-resistant and prevents formation of structurally ...

Siemens has finished its first full-load engine tests for gas turbine blades completely produced using Additive Manufacturing (AM) technology. The company successfully validated multiple AM printed ...
