“…This deposition technique is classified into two categories: a powder mixed in the dielectric medium called a powder mixed electrical discharge machining (PMEDM). Another one is the compaction of powder in the form of tool electrode by powder metallurgy (P/M) process to enhance the surface characteristics with suitable microstructural modification for improved mechanical properties [9,10]. In general, the above-mentioned deposition method broadens the sparking distance with the high-density electric field.…”

In this present work, an attempt has been made to deposit the WS 2 layer on the Al 6061-T6 alloy surface through the electrical discharge deposition (EDD) technique. Specified deposition parameters, namely powder concentration (C p ), pulse-on time (P on ), and gap voltage (V g ) with various levels considered during the EDD process. The experimentation was performed for analysing the results of deposition parameters on material deposition rate (MDR), surface roughness (SR), microhardness (MH), layer thickness (LT), and surface characteristics of the WS 2 layer were examined. The results addressed the various intermetallic compounds formed on the deposited surface. A multi-objective optimisation using Box-Behnken design of response surface methodology was utilised to conduct the deposition process. To predict and optimise the appropriate MDR, SR, MH, and LT, the quadratic model was developed using regression analysis and analysis of variance. Based on the developed model, the interaction effects of deposition parameters on the EDD process were explored. The optimal depositing parameters are determined by maximising the MDR and MH and minimising the SR and LT. The validation test results confirm that experimental data are good in agreement with the predicted results, and hence, the model is feasible to predict the responses adequately. The tribological study was carried out for the optimised condition, and surface characteristics on the worn-out surface were analysed. When compared to the base material, the obtained results show a lower coefficient of friction and specific wear rate.

Alloying was conducted on Al 7075 alloy by reinforcement of the metallic portion of molybdenum (Mo) in po wder blended with dielectric fluid to strengthen wear resistance a nd investigate the lubing features of this woven surface. The present work features alloying of Al 7075 with Mo as a vital material. Mechanical attributes along with powder frustration and layered coating size and shape were investigated by scanning electron microscope (SEM), energy dispersive X-ray analysis (EDXA), optical microscope (OM), surface texture with roughness tester and wear vision using pin on disc device. The effect of Peak current (A), Pulse on time (Pon) and Pulse off time (Poff) on the wear execution of an alloyed discharge, Al 7075 auxiliary materials have also been considered using Response Surface Methodology (RSM). Analysis of Variance (ANOVA) was interpreted to add to the effectiveness of material variables on the performance characteristics. Confirmation tests were performed to compare the predicted values with the experimental values and it was found that the results matched well with the experimental results.
