Coating removal from the components and structures is an important process as it affects the surface quality and leads to various failures. This study deals with the study of coating removal by using abrasive jet and investigation of parameters which are affecting the coating removal rate. An experimental setup was designed and fabricated in order to investigate the effect of Standoff Distance (SOD), horizontal and vertical angel between the work piece and abrasive jet nozzle and the exit diameter of abrasive jet nozzle on coating removal rate. Experiments were conducted by varying the striking angle of abrasive jet from 0 to 70°, SOD from 150 to 200 mm and the nozzle diameter as 8 and 10 mm to evaluate the effect of various parameters on coating removal rate. The results of the experiments revealed that the time taken for removing the coating form the work piece is found to be reducing and which enhances the coating removal rate when the horizontal striking angle is between 0 to 50°, SOD is 160 mm and the nozzle diameter is 8 mm.
