Erosion–corrosion of Al-Mg-Si aluminum alloy in NaCl–water solutions were studied by weight-loss measurements through an impingement jet system. The effect of sand concentration and fluid impingement angle, were investigated. The sand used is Iraqi silica sand from Al-ardhimah .The result showed that, increasing erosion time, will increase the erosion rate of alloy samples for all sand concentration and impact angels. When the sand concentration is increased the erosion-corrosion rate of alloy samples will increase, and the maximum value of erosion –corrosion rates occur when the impact angle is about( 45◦).The surface morphologies of eroded surface after abrasive water-jetting, show that erosion rather than corrosion, controls the total Erosion-Corrosion rate of Al-Mg-Si alloy in sand-containing NaCl–water solutions.
