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.
Highlights
Erosion is the degradation of the solid target surface due to impingement of solid and/or liquid particles
Material is removed from the target surface due to impingement of solid particles entrained in liquid medium [1]
The maximum erosion takes place for bare material specimens and minimum erosion is for hard facing alloy 2
Summary
Erosion is the degradation of the solid target surface due to impingement of solid and/or liquid particles. Keywords Slurry Erosion, Hard Facing, Coating, Impact, Particle Size Three parameters namely average particle size, speed(rpm), and slurry erosion were studied. The base material i.e. AISI 316L stainless steel was Hard Faced with Cobalt based (stellite 6) and Titanium based electrodes.
