Purpose: This work deals with solid particle erosion behavior of Inconel 718 at elevated temperatures. Design/methodology/approach: Samples with 3 mm thickness, 25 mm diameter were tested at 3 different temperatures (20°C, 400°C and 600°C); at 4 impingement angles (30°, 45°, 60°, 90°) in a specially designed erosion test rig by using 120 mesh (90-125 μm) Al2O3 abrasive particles. Solid particle erosion damage characterization was achieved by evaluating the erosion rates after tests. Damage mechanisms were discussed by using scanning electron microscope (SEM) analysis. Surface topographies were analyzed in order to evaluate the effects of experimental parameters on solid particle erosion. Findings: Although the conclusion of this work is crucial for understanding the solid particle erosion behavior of Inconel 718 alloy used in turbine blades of aircraft gas turbine engines. Practical implications: This work may contribute to develop next generation alloys to be utilized in manufacturing of compressor blades exhibiting longer service durations. Originality/value: More detailed study about erosive wear performance of Inconel 718 as an aviation engineering material is crucial for future work.
