Study of Surface Parameters of Inconel 600 by Extrusion Honing Process

Abstract

Extrusion Honing (EH) is also known as Abrasive flow machining (AFM) is an effective method that is used to deburr, clean, polish, remove recast layer and micro cracks by flowing pressurized semisolid abrasive laden visco-elastic media over those surfaces. Inconel 600 is one of the most difficult-to-cut materials because of its low thermal diffusive property, high hardness and high strength at elevated temperature. In this paper, the influence of the process parameters on surface roughness is investigated on Inconel 600 material. The processed surfaces were measured and analyzed with the help of surface roughness tester and Scanning Electron Microscope (SEM). Results show a significant improvement in surface finish and EH/AFM is capable of removing the micro cracks and recast layer.
