Electric Discharge Machining of an Aluminium Alloy Silicon Carbide Reinforced Metal Matrix Composite

Electric discharge machining of Al–10%SiCP as-cast metal matrix composites

“…Despite the low electrical conductivity and high thermal resistance of the SiC reinforced particles, which ultimately reduces the electrical conductivity of the work material, the results obtained indicate that Al-10%SiC P can be machined effectively using EDM. These results are in good agreement with the observations of many researchers [9,15,16,19,20].…”

“…At higher ratings, it is more pronounced and hence the SiC particles could have been deposited below the recast layer. De Silva and Ranke [19] have reported similar trend on machining Al-Li/SiC composites and also by Le Roux et al [20] on machining 2618/SiC composites. Further, random voids are seen which may be due to imperfect joining of the molten droplets or would have been resulted from the trapped gas during resolidification similar to that of Hung et al [13].…”

Fabrication and electrical discharge machining of metal–matrix composites: A review

“…It was also observed that the reinforced particles were flushed away or deposited below the recast layer with the melted portion of matrix at higher rating of discharge energy. 11,28,58,59…”
