Experimental Investigation of Slurry Erosion Behaviour of Hard Faced AISI 316L Stainless Steel

Abstract

The slurry Erosion behaviour of AISI 316L stainless steel has been investigated in this research work. The samples hard faced with cobalt based (stellite-6) and titanium based alloys specimens were used during the experimentation. Erosion test was performed on a Slurry Erosion test rig fabricated as per ASTM standards G73. Three variables which were used in the experimentation are concentration level of the Slurry, nozzle diameter of the jet and average particle size of erodent. After a fix time, weight loss of samples was compared. It was found that the samples hard faced with titanium based alloy are more hard than hard faced with cobalt based alloy and substrate material.
