Parametric optimization of slurry erosion behaviour of brass (original) (raw)

This paper deals with experimental study conducted on slurry erosion pot tester to examine the effect of different parameters on erosion wear. Bottom ash is taken as the erodent material with varying concentration. The Taguchi's approach with L 9 (3 2) orthogonal array is used to assess test data. By using the Taguchi's DOE (Design of Experimentation) influence of test parameters such as rotational speed (N), solid concentration (C W) and testing time duration (T) on erosion wear could be estimated by computing signal-to-noise ratio and analysis of variance. From analysis of test results, erosion wear in brass has been found in order of N > C W > (T). Based on experimental data it is clearly revealed that erosion wear have strong dependence on parameters like N, CW and T.
