“…Tyagi R et al [16] developed a solid lubricant coating by EDC process with WS 2 : Cu green compact electrode and observed a reduction in microhardness, and material loss during wear performance. Rao SS et al [17] evaluated the adhesion strength of the coating surface by scratch test and reported better adhesion strength at higher current values.…”

This paper reports solid lubricant coating on the M2 high-speed steel substrate with MoS2:Cu (50:50) green compact electrode by electric discharge coating (EDC) process. The influence of input parameters (peak current(I) and pulse duration(ton)) on the coating responses (thickness, microhardness, and surface roughness) have been investigated. The coated materials atomic weight percentage and chemical compounds are examined through EDS and XRD analysis. The maximum coating thickness (695.3µm) reported at ton - 750 µs and I- 5A. The coated samples microhardness exhibit between 217.8 HV – 669.43 HV, which is lesser than the substrate (750 HV). The adhesive strength of the coating surface was examined using scratch test with progressive load. The result shows, adhesive strength increased at higher current level.

This research explores the efficiency of Electrical Discharge Coating (EDC) as an advanced surface modification technique using powder suspension, conventional electrodes, and 3D printed electrodes (3DPE), focusing on Ti6Al4V alloys. Conventional Ti electrodes resulted in 100% titanium content with a thickness of 110 µm, while the powder suspension coating was inadequate. The use of 3D printed electrodes showed promising results, with uniform deposition of 61.20 µm thickness and enhanced surface properties under 10 A current. Further analysis of 3D printed Ti6Al4V EDC revealed a higher Ti percentage of 44.20%, TiC formation of 84.17%, and enhanced microhardness with lower surface roughness. Thorough optimization of 3D printed electrode EDC has been undertaken. The study suggests the potential replacement of traditional electrodes such as powder metallurgy with 3D printed counterparts, advancing surface modification techniques and opening new avenues for materials engineering and manufacturing processes.
