Investigation of the WEDM Parameters’ Influence on the Recast Layer Thickness of Spark Plasma Sintered SiC-TiB2-TiC Ceramic

Coatings, 2023
The influence of WEDM parameters (Spark gap voltage, Pulse-on time, Spark frequency, and Wire speed) on the recast layer thickness and surface roughness of Spark Plasma Sintered SiC-TiB2-TiC ceramic composite was investigated. For this, an orthogonal L9 Taguchi design was used, and grey relational analysis was carried out for multi-response WEDM ...
