AbstractThis article presents the theoretical modeling and computation of liquid impingement erosion of solid metallic surface and the response mechanisms, with special interest in study of the liquid impingement erosion behavior of NiAl alloy. Particular attention is paid to investigating the effects of drop velocity and drop size on the damage of the target surface and to predicting and simulating the erosive failures. The models of impact stress wave, mean depth of penetration, and maximum depth of erosion rate (Max DER) are employed to develop various maps for NiAl alloy, including target thickness vs. drop size (diameter), rate of mean depth of penetration (MDRP) vs. drop impact velocity, and damage threshold velocity (DTV) vs. drop size. For comparison, pure Ni target and steel ball erodent are also studied. The computational results are analyzed and discussed. © 2014 Elsevier B.V.
