Abstract

In order to simulate the water erosion process of blades in final turbine stage under the actual operating conditions, the water erosion experiment system has been designed and built in the present research. High-speed water jet was used to impact three kinds of structural steel material under three impact angle (30°, 60°, and 90°) to obtain the cumulative erosion-time curves of specimen. The incubation period and maximum erosion rate are chosen as the criterion to evaluate the erosion resistance of the testing materials. Based on the mechanical properties of testing materials, it is figured out that water erosion resistance of materials is influenced by different mechanical properties (hardness, tensile Strength, elasticity and shear modulus) at different stages. According to the characteristic size changes in width and depth of erosion craters, it is verified that the shear effect of lateral jet is greater than the impact effect of normal jet.
