Design of Experiments to Study Slurry Erosive Wear Behavior of Inconel-718 Coatings on Copper

Abstract

The present work is aimed at investigating the effect of speed , slurry concentration and particle size on Inconel-718 coatings on copper subjected to slurry erosion with the help of DOE (design of experiments) tool among which the Taguchi technique is well known. The coatings are subjected to slurry erosive wear tests in 3.5% NaCl solution (35 gms NaCl/ ltr of water) with sand as erodent. On application of analysis of variance, it is found that all three parameters namely speed, sand concentration of the slurry and particle size are significant with speed being the most significant one.
