Hardly any form of modern energy production has greater green potential than hydroelectric power – water is the sole driving force behind the energy. Unfortunately, that same force leads to continuous wear and tear, especially from cavitation, impact, sediment, and vibration on turbines and other components. Conventional polymer repairs like epoxy or ceramic coatings often fail under these extreme loads.
Why hydroelectric components wear out
-
High-velocity water flow causes constant pressure fluctuations and cavitation.
-
Debris and sediment strike metal surfaces at speed.
-
Vibration and fluctuating loads weaken coatings and structures over time.
-
Standard polymer or epoxy coatings often lack the elasticity and impact resistance needed.
