Background / Objectives: In this paper, erosion wear response of slurry pipeline material is optimized by utilizing Taguchi’s experimental technique. Methods / Statistical Analysis: The investigation of erosion wear due to solid–liquid mixture flow took place with the assistance of a slurry erosion pot tester. The pipe material namely stainless steel SS-317L is utilized to lead the erosion tests. This erosion test is set up to impact the rotational speed, solid concentration and time with multi sized slurry. Fly ash was utilized as the erodent material. Findings: In these erosion tests, four experiments were performed. These four tests are performed at four different speeds 600, 850, 1100 & 1350 rpm and the concentration of solid-liquid mixture is 30%, 40%, 50 & 60% with time duration of these experiments are 60, 120, 180 and 240 min. Improvements / Applications: For protective coating, High-velocity oxygen-fuel (HVOF) spray process is used for depositing to coating powders Stellite-6 and WC - 12Co - 4Cr on the material namely stainless steel SS-317L. The S/N ratio of with and without HVOF coating of SS-317L varies from 44.88 to 29.77 (Uncoated), 64.43 to 37.09 (Stellite-6) and 80.00 to 49.25 (WC-12Co-4Cr) respectively. Rotational speed was resolved as one of the predominant factor which impacts the erosion wear response of SS-317L.
