Abstract

Slurry abrasion test equipment is used to evaluate the abrasive wear behaviour of these composites in a slurry environment (ASTM G105). The hardfacing for the PTA is now complete. The base metal is AISI 316L stainless steel, and the hardfaced material is tungsten carbide powder. To progress an empirical relationship to forecast the wear loss of the deposits at the 95 percent confidence level, statistical procedures such as analysis of variance are applied (ANOVA) and design of experiments (DoE). The response surface methodology (RSM) idea is used to create response graphs and contour plots. PTA process parameters including travel speed (TS), transferred arc current (TC), stand-off distance (SD), and powder feed rate (PF) were all optimized in this study. The effect of different processing variables on wear rate is studied. The deposit produced with an arc current of 170.41 Amps, a PF of 30.74 g/min, TS of 185.00 mm/min, and a stand-off distance of 11.00 mm had a minimum wear rate of 0.0098mg, according to this experiment
