Controlled testing throughout the turbine-blade development process is critical to selecting materials and manufacturing processes to limit leading-edge and water-droplet erosion damage and to predict their success in the field.

Water droplet erosion (WDE) is the loss of solid material from a surface due to repeated small-scale, high-intensity pressure pulses produced by the impact of high-speed water droplets. Damage from WDE is seen in many applications including steam-turbine blades, aircraft, and missiles, as well as wind-turbine blades. Turbine blades are particularly susceptible to roughening of […]

In today’s environment, companies need to be able to also make high confidence asset integrity decisions, enabling them to increase the profitability and productivity of the asset base while minimizing the exposure to the risk of catastrophic events.
