|Abstract:||In this paper a systematic study has been undertaken to study the erosive wear analysis of 2.25Cr-1Mo steel in normalised and thermally aged conditions. The design of experimental technique using Taguchi’s orthogonal array is used to carry out experiments in an air jet erosion tester. The L9 orthogonal array is used to study the effect of erodent size, impact angle, impact velocity and erodent temperature on erosive wear of 2.25Cr-1Mo steel both in normalised and thermally aged conditions. The results indicate that in case of normalised condition, impact velocity is found to be the significant factor which results in maximum erosion and in case of thermally aged condition erodent size is the most powerful factor influencing the wear response. The confirmation test is carried out by taking an arbitrary set of parameters. The existing model predicts the erosion rate with reasonable accuracy. The contour plots are used to analyze the interaction of various design parameters with the significant controlling factor and erosion rate.|
