Erosive wear is material removal due to the impingement of granular flow. In the present work, the effects of influencing parameters including flow velocity, incidence angle and grain size on erosive behavior of AISI1020 subjected to a flow of SiC particles has been investigated by employing an erosion wear test machine. The experiments have been performed at the different values of impact angle, flow velocity and particle size. Two tests have been performed for every set of conditions and the average of them has been presented. Results showed that the erosive wear maximizes at the impact angles of 30° and 45°. The flow of small particles resulted in more wear contrast to the large particles. Results also indicated that the influence of flow velocity was higher than the influence of impact angle and particle size. It means that minimizing the flow velocity results in more efficient results to reduce erosion. Moreover, the experimental data were used to determine appropriate coefficients for using in an erosion equation given by literature. New factors gave erosion evaluations which had appropriate accordance with the experimental data.
Key words: Erosive wear / flow velocity / impingement angle / particle size / experiment / erosion equation coefficients
