SLURRY EROSION OF ULTRA HIGH STRENGTH BAINITIC STEEL

Abstract

Newly developed ultra-high strength bainitic steels have very good mechanical properties and potential materials for heavy wear applications. In the current work, an effort has been made to determine erosion behaviour of ultra-high strength bainitic steel in slurry environment. The erosion wear tests were carried out on slurry pot erosion tester with different impact angles and time. 5 wt% slurry concentration is used for the test. The weight loss of the material measured after the erosion tests and worn surfaces were analysed by scanning electron microscopy. Surface roughness of the samples were also analysed before the tests so that initial condition remain same. This dissertation includes six chapters in which Chapter 1 gives the brief introduction of the ultra-high strength bainitic steel. Chapter 2 gives the general description of the theoretical background of erosion. Chapter 3 discusses about objective of present work. Chapter 4 gives the description about the experimental methodology employed for this dissertation work. Chapter 5 discusses about the results obtained for various experiments conducted. Chapter 6 gives the conclusions of the overall dissertation work. Suggestions for future work and references are given at the end of the dissertation
