Several cases relating the damage mechanisms associated with blades failures, e.g., corrosion-erosion, carbides precipitation, oxidation, coating degradation, high and low cycle fatigue, and creep, are discussed. To converge the topic, the work focuses on gas and wind turbine blades only.

Can rough surface damage a wind turbine blade?

The damaged, rough surface can reduce the aerodynamic performance of blades and energy generation. It does not prevent the wind turbine from functioning, but the surface defects grow and develop and can lead to structural damage of the blade. Generally, failure mechanisms of wind turbine blades are analyzed using the following main methods:

Do wind turbine blades erode?
