EVALUATION OF EROSION WEAR OF A CERAMIC COATING WITH TAGUCHI APPROACH

Abstract

Solid particle erosion is a complex surface damage process influenced by a number of control parameters that collectively determine the erosion rate. The present piece of work investigates the significant process parameters which affect the solid particle erosion wear behaviour of fly ash – quartz coatings, using Taguchi analysis technique. It is found that the impact angle is the most powerful influencing factor for the erosion wear of the coatings. Further, when erosive wear behavior of the coating was investigated at three impact angles (i.e. at 30 0 , 60 0 , 90 0 ), revealed that maximum erosion takes place at 90 0 impact angle .
