Abstract
"The proposed Corrosion/Erosion Resistant (C/ER) coating is amulti-layered "Titanium-Nitride" coating that is applied todifferent compressor airfoils via a Cathodic-Arc PhysicalVapor Deposition process.The C/ER coating has been applied to over 2000 Russianmanufactured TV2-117 turboshaft engines and demonstratedsignificant operational savings due to decreasedrejection of compressor airfoils, decreased fuelconsumption and increased operational hours beforeengine overhaul. In addition, the C/ER coatingrecently completed a successful Foreign Comparative Test(FCT) test & evaluation program for application on aGE T64-419 turboshaft engine.The C/ER Coating process and composition can be optimizedfor different gas turbine engine compressor systems andsubsystems. For example, the coating composition can beenhanced to provide greater corrosion protection and maintainerosion protection, and the coating application can beoptimized for application on single compressor airfoils, vanesegments, blisk rotors and centrifugal compressors. The anticipated benefits of the C/ER Caoting includes decreased totalownership cost to the operator via: a reduced number of compressor airfoilsubsystems rejected due to corrosion or erosion; increased engineperformance due to decreased compressor degradation, increased mean-timebetween engine repair and increased engine time-on-wing.These anticipated benefits can be realized for gas turbine compressionsystems and s
