STUDY ON SLURRY EROSION OF DIFFERENT HEAT-TREATED STEEL

Abstract

The objective of this dissertation is to study the slurry erosion behaviour of Low Carbon alloy steel treated under different heat treatments.Applications of this particular alloy steel includes in earthmoving, mining, and ore processing which are subjected to high erosion. An experimental study was conducted to assess the erosion in wet environments on normalized, annealed and quenched samples of the particular alloy steel. A testing apparatus was constructed based on the slurry pot erosion test method followed by Knuutila.Keeping the same conditions tests were repeated for all samples. This study is focussed on review and testing of wear behaviour for varying hardness and phase. Various wear mechanisms were assessed through scanning electron microscopy analysis. Results were found to be consistent with the inverse relation between Hardness and wear rate.
