“…The reason is that the thickness of the coating (3µm) is too small. The surface roughness (Ra) was also reduced as compared with uncoated tools [12]. The TiC-Cu powder tool electrode was prepared with composite coating on AISI 1020 steel by the electrodischarge coating (EDC) process.…”

“…The copper coated aluminum (Al) electrodes could significantly affects the MRR, TWR and Ra in EDM process [17]. The CNT coated electrode and TiN coated electrodes can also increase the efficiency of the EDM process compared to uncoated electrodes [18][19][20]. The study portrayed the potential of the EDM input parameters for improving the MRR and surface quality of Co-Cr alloy and DSS alloy [21].…”

The coated electrodes with high heat resistant alloy materials can considerably improve the efficiency of electrical discharge machining (EDM) process. In the present study, the influence of Aluminum Chromium Nickel Coated aluminium electrode was investigated on the quality criteria using EDM while machining Titanium alloy (Ti -6Al-4V). The peak current, gap voltage and pulse-on time were used as input parameters to analyze the material removal rate, tool wear rate and surface roughness under the L16 based Taguchi method and ANOVA method. It was observed that Aluminum Chromium Nickel (AlCrNi) coated electrode could produce higher material removal rate (MRR), lower of tool wear rate (TWR) and surface roughness (Ra) than uncoated electrode. Compared with EDM with uncoated electrodes, the quality indicators in EDM with coated electrode are better, namely 8% higher MRR, the lower TWR and Ra are 8% and 24%, respectively. The better surface finish was also observed with the coated electrode due to its thermal conductivity.
