Wear Analysis of Manganese Steel in Order to Develop Mathematical Model

Manganese steel, commonly known as Hadfield steel, offers exceptional strength, toughness, corrosion resistance, and durability against heavy impact and abrasion, making it suitable for a wide range of industrial applications. However, the limited research on wear phenomena during operation hinders its broader application. Therefore, this study extensively examines the factors contributing to wear in manganese steel, with a focus on raw coal as abrasive particles. The work begins by selecting two coal particle sizes (500 µm and 710 µm) as abrasives, which are positioned between the disc and the manganese steel pin. The experiments also investigate the effect of load, ranging from 20 to 35 N, on the wear behavior of manganese steel. Additionally, SEM images of all wear tracks are captured at the same magnification to analyze changes in wear patterns. The study found that larger abrasive particles have a more detrimental impact on wear compared to smaller ones. Furthermore, a mathematical model is developed to predict theoretical wear losses based on experimental results. The findings demonstrate that the mathematical model aligns well with the experimental data, supporting its applicability in real-world scenarios.
