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.
