Abstract
The slurry handling industrial pumps, pipes carrying minerals, and slurry processing equipment are prone to worn out by particulate flow. The relative motion of abrasive particles suspended in slurries induces the wear of mining components in such applications. Wear by slurry abrasion is dependent on several parameters such as hardness of abrasive and the surface and service conditions. The work reported here aims at the effect of these parameters on the slurry abrasion of hardened and tempered En 24 steel. The microstructural characterization of specimens was carried out by Scanning electron microscopy, and X-ray diffraction analysis. A slurry abrasion test rig was used to evaluate the wear rate, in which slurries of silica sand, iron ore, and limestone were used as a slurry medium. The wear loss increased with the trend with an increase in abrasive hardness. The observations of worn surfaces have been explained using electron scanning electron microscopy.
