Experimental investigations on erosion of carbon steels involving textured surfaces

Abstract

The paper aims to report the comparative of erosion on conventional vis a vis textured carbon steel surfaces wherein alumina particles have been used as erodent. Shaping and stamping processes were employed to prepare textured surfaces on carbon steel that comprised of trapezoidal and rasp shapes. Experiments were performed employing alumina particles as erodent striking the carbon steel plates at the impact angles of 15°, 30°and 45°. With due consideration to the particle aspect during exploration, the erodent was made to strike the surface with two impact velocities of 30m s −1 and 60 m s −1 . With the aforesaid parameters and surface condition, experiment was performed for both unhardened and hardened surfaces (total 36 test specimen were used). Textured carbon steel (comprising trapezoidal shape) yielded significant reductions (40%-50%) in erosion in comparison to the conventional case. The reduction in erosion for rasp shape specimen was in a range of 15%-17%. It is worth noting here that the presence of texture has immensely contributed in erosion reduction of unhardened samples as compared to the hardened conventional samples.

Erosion characteristics on surface texture of additively manufactured AlSi10Mg alloy in SiO2 quartz added slurry environment

“…There are many types of wear, and one of the most common problems is an erosive wear (Bansal et al , 2020; Fouad et al , 2011; Venter et al , 2020). About erosive wear, there are also many different wear types (Raadnui, 2021; Saleh et al , 2021; Verma, 2020). Slurry erosive wear is one of these wear types and occurs especially in liquid environments containing a certain quantity of solid particles (Heshmat and Abdelrhman, 2021; Kumar et al , 2020).…”
