Optimization and Erosion Wear Response of HVOF Coated Pipeline Material at Different Impingement Angles


Background/Objectives: Erosion wear characteristic of pipeline material namely stainless steel SS-317L has been investigated with the help of a pot tester under various concentrations and fly ash as erodent was used. Methods/Statistical Analysis: In this paper, erosion wear response of slurry pipeline material is optimized by utilizing Taguchi’s experimental technique. Findings: The phenomenon of erosion wear response is too complex and the behavior has been studied. In this paper, the attempt has been made to expand a methodology to optimize the erosion wear response of pipeline material at various impingement angles 30, 45, 60 and 90 degree with the help of a mixture of slurry with water under various concentrations i.e. 30%, 40%, 50% and 60%. Fly ash and water was used as erodent to prepare the slurry mixture under various concentrations at different rotational were 600, 850, 1100 and 1350 rpm and time period of 60, 120, 180 and 210 min. Improvements/Applications: Erosion wear response is investigated with HVOF spayed coatings. It is also observed that the erosion wear response of WC-12Co-4Cr and Stellite-6 coated pipeline material SS-317L increase with the increase in the impingement angle till 30 degree observe maximum value and decreases with the impingement angle 90 degree.
