Solid Particle Erosion as Influenced by Tensile Axial Loads

Abstract

In this study, the effects of external loads and impingement angle on erosive wear of AISI 1010 steels were investigated. Tensile axial loads corresponding to 0, 20, 40, and 60% of the specimen material's yield strength were applied on specimens attached to a specially designed specimen holder. The erosion tests were conducted at impact angles of 15, 30, 45, 60, 75, and 90° for each loading. Particles with angular geometry were used as abrasive steel grits and their impact velocities were adjusted by changing air pressure. The impact velocity of the particles was set at 30 m/s. Graphs of erosion rates as a function of stress and impact angles were constructed based on specimens’ weight loss obtained at the end of the tests. It was found that there was a slightly increase in erosion rate as a result of increased tensile stress. It was also found that the erosion rate increased between 0 and 30°, whereas between 30 and 90° impingement angles, the erosion rate was seen to fall.
