Microstructural and Erosive Wear Characteristics of a High Chromium Cast Iron

Surface material loss due to erosive wear is responsible for the increased cost of maintenance and downtime in industries. Hence, hardfacing one most valuable effective techniques employed improve resistance heavy-duty components. The present paper investigates microstructural characteristics a hypereutectic high-chromium cast iron, considering erosion resistance, resulting from impact micro-sized particles, both as-received heat-treated conditions. Micro-sized particles involve erosion-resistant carbide matrix, contemporary. Due this, enhancement matrix strength could mechanical support withstand cracking deformation spalling. Accordingly, effect destabilization heat treatment on microstructure was firstly investigated by hardness tests, X-ray diffraction analyses, optical scanning electron microscopy. Specifically designed tests were carried out using raw meal powder at an impingement angle 90°. superior samples relayed improved microstructure: consistent with observed eroded surfaces, reduced matrix/carbides difference pivotal enhancing hardfacing. results contribute better understanding microstructure–property relationships concerning resistance.
