Examining the surface roughness and kerf quality of micro-slots cut on the surfaces of Ti-B₄C nanocomposites by WEDM: a desirability approach

Abstract Micro slots and textures are created on Titanium (Ti) composites to improve its surface characteristics. Micro-textured Ti generally recommended for bio implants, automobile, aerospace components. In the current research, Ti-B 4 C nanocomposites were prepared by powder metallurgical route. cut surfaces Wire Electrical Discharge Machining (WEDM) Technology varying current, pulse-ON time, pulse-OFF time. Scanning electron microscopy XRD analysis validates uniform distribution inclusion of B nanoparticles in matrix. Response methodology was used plan experimental runs. Analysis variance desirability employed identify most suitable machining factors obtaining minimum roughness, lower kerf width higher material removal rate (MRR). Increase applied increases MRR. time from 50 μ s 60 gradually reduces MRR reduce roughness slots. Contrastingly an increase due extensive melting resolidification nanocomposites. The morphology WEDMed reveals recast layer localized zones surfaces.
