Improving Cyclic Oxidation Resistance of Additively Manufactured IN939 Superalloy via Chemical Vapor Aluminizing

Advanced Engineering Materials, Volume 27, Issue 7, April 2025.
This study investigates the effect of a NiAl coating on additively manufactured (AM) IN939 to improve its cyclic oxidation resistance at 1050 °C. The coating promotes protective α‐Al2O3 formation, allowing durability for up to 240 cycles, while uncoated AM‐IN939 experiences spallation and weight loss due to nonprotective oxides.

Multiperspective Structural Integrity Investigations on the Rotor Blade of Axial Flow Compressor Under Various Rotodynamic Loading Conditions Using Enhanced Computational Analyses

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
Small gas turbine (SGT) engines power the latest generation of unmanned aerial vehicles (UAVs). This study investigates the axial flow–natured rotor blades of an SGT compressor. Rotor structures in axial flow compressors have failed due to complex stress scenarios.

Multiobjective Optimization of Fiber Laser Trepan Drilling for Stainless Steel Using Taguchi–Grey Relational Analysis

Journal of Engineering, Volume 2025, Issue 1, 2025.
The present work focuses on optimizing spatter size, taper angle, and circularity simultaneously during fiber laser trepan drilling of stainless steel thin sheet using Taguchi–grey relational analysis (GRA). The controllable process factors such as trepanning speed, average laser power, and pulse frequency with five levels are applied to conduct the ...
