Abstract
This study presents electric discharge coating of SiC-Cu on Al-6351 alloy using EDM oil as dielectric. The electrode is made by green compaction powder metallurgy process. A Taguchi design of experiments is used to study the sensitivity of EDC response parameters like Material Deposition Rate (MDR) and Surface Roughness (SR) by changing process parameters such as pulse-on time, peak current, compaction load and composition. A Taguchi L16 orthogonal array with mixed levels is used as a DOE (Design of Experiment) in this present study. To explore the effect of significant process parameters, the Analysis of Variance (ANOVA) is used. Moreover, SEM and EDX analysis has been carried out to characterize the deposited layer and also to confirm the ubiquity of electrode materials on the substrate surface.
