| Abstract Scope |
This study investigated the high-cycle fatigue (HCF) behaviour of a polycrystalline nickel superalloy exposed to type II hot corrosion, replicating service-induced damage in high-temperature applications like aircraft engines. Specimens underwent pre-corrosion under service-like conditions, followed by commercial overhaul cleaning. Fatigue tests were conducted to assess the impact of corrosion on material performance, and the results were used to develop a Kitagawa-Takahashi diagram. The findings provide insights into the possible life reduction caused by hot corrosion, guiding the design and maintenance of components in corrosive, high-stress environments. |
