Abstract

Gas turbines play a key role in industries such as aeronautics, maritime, and power
generation, but high operating temperatures in these settings would expose critical
components, particularly turbine blades, to significant wear. Among the multiple
failure modes, erosion induced by high-velocity particle impacts is identified as
one of the primary causes of turbine blade degradation. This review provides a
comprehensive analysis of erosion-induced failure mechanisms in gas turbine blades,
emphasizing recent advancements in understanding erosion processes, material
degradation, and mitigation strategies. Key areas covered include the impacts of
solid particle erosion, the effectiveness of erosion-resistant coatings, and the role
of superalloys designed for high-temperature resilience. Furthermore, this review
explores how computational models, such as machine learning, computational fluid
dynamics, and finite element analysis, contribute to predicting erosion patterns and
