Field Evaluation of Six Protective Coatings Applied to T-56 Turbine Blades After 2500 Hours of Engine Use
Abstract
This report outlines an assessment of the performance of six different aluminide coatings applied to Allison T-56 high-pressure turbine blades after 2500 hours of engine operation. The results confirm the superior resistance of the precious metal (platinum and platinum/rhodium) modified aluminide coatings to high temperature oxidation and hot-corrosion, as previously indicated by the earlier progressive evaluations at 500, 1500 and 2000 hour intervals.
