WebIn addition, the erosion rate increased with impact velocity. The surface roughness increased with either increasing testing time or impact velocity. Hloch et al. observed the effects of hydrodynamic ductile erosion on aluminum through a pulsed water jet moving in an inclined trajectory. Different erosion regimes were obtained by moving the ... WebWater can be either static during shutdown periods or have movement. At low movement speed, the cathode reactants affect the rate of the erosion corrosion process. This most usually brings about higher rates of deterioration, but there are some cases – in the case of passive alloys, that this results in decreased rates.
