Surface roughness assessments and comparative study of Inconel 625 and Inconel 718 alloys after micro electrochemical machining

Abstract

Conventional boring is not yet suitable for dealing with Inconel and Inconel super-alloys because these materials are harder to eliminate contaminants. The purpose of this paper is to assess the two distinct alloys based on experimental results from the micro electro-chemical machining method on surface roughness. While metals have been removed during milling operation, the alloys were kept within an electrolyte concentration, owing to this surface roughness was a major problem. This study aimed to compare the surface roughness attributes of Inconel 625 and 718 alloys from empirical results done by existing literature. Only when the investigators utilize the identical devices to investigate the same process factors, empirical data are used for comparative study. Inconel 625 alloy attained the best achievable result of a surface roughness value of 0.3853 μm. The significances of surface roughness on Inconel alloys are contrasted.
