Abstract
Erosion wear is recognized as an engineering problem for slurry handling equipments. It plays an important role in design and operation of slurry transportation systems. The present work reports experimental and theoretical investigations of erosion wear of carbon steel and stainless steel in sandwater mixture. However, carbon steel (AISI-CS1060) and stainless steel (AISI-SS316L). They have been chosen as target materials, and then studied the effect of various parameters that may leads to good understanding to the erosion behavior of ductile materials such as impact angle, particle velocity as well as erosion time on erosion wear. The impingement jet erosion test rig built at our laboratory in order to carry out the experimental results. Aluminum oxide (Al2O3) is used as erodent particles after it mixed with water for slurry preparation at various impact angles of 15°, 30°, 60° and 90°, the solid concentration range of (10-30) wt%, for sized ranging between of 800µm to1700µm in the velocity range of 5 m/s to 24 m/s, with periodic time of 10 minutes at room temperature. The data points that collected in this work showed that the experimental values are agreement with the ductile erosion behavior for both materials, also showed that the erosion rate increasing linearly with increases in impact velocity and erosion time, also showed scars were characterized by an elliptical shape at 15° and 30° whereas a nearly circular shape was observed at 60° and 90° due to the horizontal component of velocity at shallow angles has value more than the normal component of velocity whereas in contrast at high angles.
