Powder Metallurgy Route

Electrical discharge machining (EDM), a thermo-mechanical machining process, is used in producing complicated intrinsic cavity in difficult-to- machine materials with excellent surface finish. One of the major disadvantage of EDM process is the tool wear, which can be used advantageously for coating purpose. Coating is a unique method of EDM process by the use of electrode prepared via powder metallurgy route. Copper and tungsten powders in weight percentage of 30 and 70 respectively are used for the preparation of the tool electrode by varying the PM process parameters like compaction pressure and sintering temperature. The substrate on which coating is made is chosen as AISI 1040 stainless steel with EDM oil as the dielectric fluid. During coating, influence of parameters like discharge current, duty cycle and pulse-on-time on material deposition rate, tool wear rate and radial under deposition are studied. To find out the best parametric combination Grey Relational Analysis method combined with Harmony Search algorithm has been employed.
