Abstract

© 2019 Elsevier B.V. Solid particle erosion (SPE) has been extensively studied in engineering materials due to the frequent failure of components in rotating machinery, such as: solid blades, channel walls of a gas turbine also in oil pipelines, among others. The effect of temperature, speed, angle of impact and the geometry of the erosive particles have been studied as well. In recent works, it has been reported that erosion can be considerably increased by the effect of a swirling impact jet, which occurs in real operating situations. However, the effect of swirling flows on erosion of materials at high temperature has not been widely explored yet. Basically, this work analyzes the effect of swirling jet erosion on AISI 310 Stainless steel at 450 °C. Three angles of incidence were tested (30° 60° and 90°) under impact speed of 30 m/s. Abrasive particles of silicon carbide (SiC) with angular morphology and size of 350 µm were employed. The total exposure time for the tests was 360 s. The results show similar tendency of erosive wear rates in swirling and non-swirling conditions being higher at high temperature. Finally, plastic deformation, ploughing action and cracking wear mechanisms were the predominant.
