SPECIFIC MATERIALS USED IN MANUFACTURING
HYDRAULIC TURBINES AND THEIR BEHAVIOR TO EROSION
The goal of the paper is regarding the alloy materials used in the
manufacturing of hydraulic machines and how the process of corrosion has
influenced these materials. The mechanism of silt erosion is discussed and are
compared the effects of erosion and cavitational phenomena.
