Tungsten carbide (WC) composites are specialized materials that have been found effective and useful for many industrial applications. This article reports the results of a research study conducted on wire electric discharge (WEDM) of WC-Co composites. Effects of WEDM parameters such as wire feed rate, voltage, pulse-on time, and pulse-off time on root mean square surface roughness of WC-Co samples have been investigated by conducting twenty-nine experiments. Process productivity in terms of material removal rate has also been investigated. It was found that the discharge energy is the key to obtain the desired surface quality during WEDM of WC-Co. Sample machined at low discharge energy parameter setting has better surface roughness and corrosion resistance as compared to one machined at high discharge energy parameter combination at a compromise with the material removal rate. Wire morphology study also confirms the suitability of low discharge energy parameter setting at which low wire erosion can be obtained.
